GENERAL :<br />
The Receiver :<br />
<strong>TIT</strong> <strong>Installation</strong> <strong>Conception</strong><br />
The types of power receivers can be very varied. The parameters below are used to characterize them. Some are<br />
directly associated with the type of power receiver and so do not need to be recorded.<br />
The type of receiver.<br />
Power supply voltage and tolerances.<br />
Phase system (single or three phase).<br />
Power rating, start-up characteristics (overcurrent, cycle and duration).<br />
The type of use: continuous, cyclic or occasional.<br />
The conditions for simultaneous operation and simultaneous start-up of several power receivers, if<br />
necessary, both in steady state and at start-up.<br />
The degree of continuous operation requirement.<br />
NETWORK TRANSFORMER IN A PIT OR COMPACT SUBSTATION :<br />
In the chapter below, the transformers of network or mini substation will be called "step down sub-station ".<br />
The step down sub-station is used to supply a power receiver or group of power receivers.<br />
The locations of the step down sub-stations and the configuration of the power receivers are determined according to<br />
conditions in the field, relating to installation of these stations and laying of LV lines, by an economic optimization<br />
calculation that takes into account the costs of the stations and LV cables, as well as the installation costs.<br />
The step down station’s power rating is determined by adding together the power of the supplied power receivers. In<br />
addition the following factors will be taken into account :<br />
Power efficiencies and factors, accessory power consumption, and possibly an incrementation factor, to<br />
determine the theoretical current.<br />
Permissible limits for power supply voltage when operating in steady state and at start-up.<br />
Ambient temperature conditions.<br />
The current/voltage characteristics of the power consumers, the predictable deterioration in electrical<br />
efficiency due to ageing, the possible extensions, to determine a working current.<br />
The start-up characteristics to define a start-up current, possibly after application of an incrementation<br />
factor.<br />
The coupling of the step down transformer will be single or three phase, depending on the design of the LV<br />
sub-network (see below).<br />
4
There are two possible types of step down sub-station, depending on its power and installation conditions :<br />
Either a TED step down station, normally installed as infrastructure in an inspection pit (power lim-<br />
ited to 160 kVA). This is an operational complete unit, equipped with two plug-in <strong>TIT</strong> terminals to<br />
ensure line continuity to the downstream sub-station, comprising the <strong>TIT</strong>/LV transformer, the <strong>TIT</strong> and<br />
LV protection, and the LV output which can be either a 6 meters cable or a plug-in terminal.<br />
Pits of watertight transformers must offer an inside volume at least equal to four times the transformer volume. In<br />
addition, they must allow cable inputs and their connection with respect to curving radius values indicated by the<br />
cable constructor.<br />
Transformers’ pits can be prefab. They must be composed of a grill equipped with a locking device by a special<br />
screw, which forbids the access to the transformer until the <strong>TIT</strong> input is not opened at the installation origin, put<br />
in circuit breaker and on earth (according to NF C 17 200 standard for road lighting installations).<br />
Or a compact internal or external station, depending on the installation conditions, comprising a dry varnish<br />
impregnated transformer.<br />
Outdoor type compact substations are designed to be installed on a concrete base, with cable output and input<br />
from the ground, under plastic wrapping.<br />
The step down sub-stations are equipped with the following electrical protection :<br />
MV side : one or more fuses whose rating(s) is/are determined according to the characteristics of the step down<br />
transformer.<br />
However this protection will only be installed when there are several <strong>TIT</strong>/LV sub-stations linked to a step up<br />
station, because otherwise it is impossible to ensure selectivity with the step up transformer’s <strong>TIT</strong> protection.<br />
LV side : The LV circuit breaker whose rating must be greater than the working current of the supplied power<br />
receivers.<br />
In the transformer : thermal probes connected to the LV circuit breaker.<br />
THE LV SUB-NETWORK<br />
Its layout depends on the terrain’s characteristics, the road layout, the possibilities for underground crossings, the<br />
locations of natural or man-made obstacles.<br />
A ground scheme must be chosen in accordance with current legislation and the continuous operation<br />
requirements. A certain number of rules will be defined as a result of this choice.<br />
These rules will determine whether or not it is necessary to install differential protection or insulation monitoring<br />
devices on the step down station, and to determine the cross-section of the LV cables, called LV feeders.<br />
These rules are defined in a general way in the standard NF C 15-100 and when appropriate also in specialized<br />
standards such as C 17200 or the C 17-205 guide for public lighting.<br />
They guarantee :<br />
Feeder protection against excess current<br />
Personnel protection against indirect contacts<br />
5
Concerning short circuit protection, as described in standard NF C 15-100 (art. 435-1 and 533-3 comments), the LV<br />
circuit breaker of the step down sub-station that ensures overcharge protection is also considered to provide short<br />
circuit protection at the same time.<br />
For road lighting installations, the C 17-205 practical guide nevertheless recommends that the minimum short-circuit<br />
rule should be satisfied, and suggests possible reductions in the line cross-section without any additional protection<br />
device.<br />
The LV sub-network of a step down sub-station as we have designed it does not comprise any reduction in<br />
cross-section, and so the case described in guide C 17-205 does not concern us.<br />
Let us consider for a moment the possibility that a short-circuit is not detected by the magnetothermal tripping<br />
device, therefore creating a continuous fault.<br />
In such a case the thermal probe protection installed in our <strong>TIT</strong>/LV sub-stations is capable of eliminating the fault,<br />
regardless of whether or not it is dangerous for the LV feeders.<br />
Given these considerations, it is not necessary to satisfy the minimum short-circuit rule, concerning LV networks<br />
supplied via TED type or compact type step down transformers.<br />
THE <strong>TIT</strong> TRANSPORTATION NETWORK<br />
The number of outputs, their layout :<br />
They are determined according to the planned locations for the different <strong>TIT</strong>/LV substations, the possibilities<br />
offered by the terrain for trench excavation, road crossings and civil engineering works.<br />
As far as possible we will make every effort to achieve balanced outputs, and when appropriate we will consider the<br />
possibility of looping-in 2 outputs together, for repair purposes.<br />
Any given output can be implemented as a single antenna, or with T branches or in a cross.<br />
The <strong>TIT</strong> transmission network obtained in this way can also be linear type, star, loop or meshed, or a combination of<br />
these different types.<br />
The general output characteristics :<br />
The output phase system must be three phase, in order to power the three phase <strong>TIT</strong>/LV sub-stations.<br />
In this case, the preferred <strong>TIT</strong> voltage will be 6600 V, 5500 V or 950 V.<br />
It should be noted that single phase <strong>TIT</strong>/LV sub-stations can however be installed on this type of output. The<br />
transformers corresponding to this configuration comprise a phase selector making it possible to balance the output<br />
charge distribution on the three phases.<br />
If the <strong>TIT</strong>/LV sub-stations are all single phase, the output can be single phase or three phase.<br />
In most cases, the single phase solution with a preferential voltage of 3200 V or 950 V is the most economic and the<br />
easiest to implement. However, when the outputs are of a considerable length, the three phase solution with single<br />
phase <strong>TIT</strong>/LV sub-stations can be selected, to reduce line drop and generally satisfy all the rules stipulated in the<br />
standards.<br />
6
Earthing scheme :<br />
The scheme will be chosen from the TNRC or TNRS schemes, that in general are the most suitable (defined in<br />
conformity with standard UTE D17 200). The neutral <strong>TIT</strong> is linked directly to ground at the installation origin.<br />
When the outputs are single phase either scheme can be selected, and the only difference is that in the TNRC<br />
scheme the <strong>TIT</strong> neutral is grounded at each <strong>TIT</strong>/LV substation, and in the TNRS scheme it is not.<br />
If the outputs are three phase the ground scheme has to be TNRS, since the neutral is not distributed.<br />
The earth connections must be made :<br />
Individual earth connections.<br />
Connection to a bare copper conductor with à minimum cross section of 25 mm² which serves as both the earth<br />
connection and an equipotential link between the luminaires.<br />
Common earth point with the luminaires connected by insulated cables.<br />
The second solution, the earth network for bonding the equipment earths comprises a bare copper conductor with a<br />
minimum cross sectional area of 25 mm² burried directly in the ground corresponding to the <strong>TIT</strong> line, is the one we<br />
recommend because it allows to obtain better resistance to earth values.<br />
Since the 1 st of October 2003, the NC C 17 200 standard imposes this second solution for road lighting.<br />
The earthing circuit this way will enable to connect :<br />
The earth point of the <strong>TIT</strong>/LV transformer.<br />
The neutral of <strong>TIT</strong> winding in a generalised earth scheme (TNR-C).<br />
The safety grid in the transformer housing.<br />
One point of the low voltage.<br />
The conducting parts of any equipment that can be accessed at the same time as that of the road lighting<br />
system.<br />
For the substation, the earth connection must be a bare conductor 25 mm² made of copper buried at about 50 cm<br />
from substation.<br />
This conductor will be depth of about 40 cm, the iron framework of the station concrete pedestal being, in that case,<br />
linked to this conductor.<br />
The transformer neutral must be connected to the earth connection to realise a TN scheme.<br />
The substation earth bonding must be connected to the earth connection :<br />
The earths of all circuits in the substation.<br />
The screens of the cable.<br />
The transformer tank.<br />
The switching devices.<br />
The metal pipework and ducting.<br />
However, the doors of the building and the metal ventilation slots should not intentionally be bonded.<br />
7
CALCULATION OF FEEDER CROSS SECTION :<br />
This calculation will be determined by the maximum authorized voltage drop, by adding together the values<br />
from the <strong>TIT</strong> and LV voltage drops. The total voltage drop must not exceed 6% for a road lighting installation, and<br />
8% in other cases.<br />
However it will be necessary to check that the protection fuse located at the circuit origin (at the step up station)<br />
makes it possible to satisfy the stipulated rules, i.e.:<br />
Protection against indirect contacts.<br />
Protection against over charges.<br />
Protection against excess current.<br />
If necessary a differential relay can be installed, if a TNRS scheme is used, to make it easier to satisfy the rules<br />
mentioned above.<br />
9
THE SUBSTATION :<br />
The substation will be step up or step down type.<br />
Implementation :<br />
As far as possible, the substation will be installed in the center of the installation. However, installation off-center<br />
is perfectly acceptable when an <strong>TIT</strong> transmission voltage is used.<br />
The implementation will be determined according to the possibilities for installation offered by the site.<br />
Nominal Power :<br />
Nominal power is determined by the sum of step-down sub-station powers, taking into account the extension<br />
possibility or non-project and by retaining a standardized transformer power.<br />
Step-up stations will be used for powers from 5 to 160 kVA for easy projects, with most often, only one <strong>TIT</strong> net-<br />
work departure.<br />
Step-down stations will be used for powers from 160 to 1250 kVA which intensities are compatible with the circuit<br />
breaking bearing of pluggable terminals of step-down watertight transformers.<br />
For service continuity reasons, it is possible to retain a transformation station equipped with two identical power<br />
transformers. One transformer supplies the whole installation in case of the failure of one of the transformers.<br />
Coupling:<br />
The type of step-up transformer coupling depends on which phase system is selected for the <strong>TIT</strong> outputs.<br />
In the case of three phase outputs, it will be three phase.<br />
In the case of single phase outputs, it can be three phase, three/two phase, three/single phase or single phase:<br />
Three phase can be selected if there are three outputs or a multiple of three. These outputs must be vir-<br />
tually balanced.<br />
Three/two phase will be selected if there are two outputs or a multiple of two. These outputs must be<br />
virtually balanced.<br />
Three/single phase is the only coupling that corresponds to all the possible situations and that allows<br />
looping of 2 outputs for repair. It implies that the primary currents will not be balanced.<br />
<strong>TIT</strong> networks control :<br />
For networks only composed with lamps, inputs will be temporary, off during the day, controlled by a photo<br />
electrical cell doubled with an astronomical clock. The control will also be realizable by current carrier using the<br />
STEP II system.<br />
For networks supplying receivers different from lamps, inputs will be permanent.<br />
For mixt networks, inputs will be permanentthe lighting control will be made by current carrier.<br />
Dimmer :<br />
It is better to put, in the transformer station, a dimmer regulator to reduce the power of lamps during weak traffic<br />
hours.The dimmer regulator allows, during hours when reduction happens, consumption savings.<br />

APPLICATION EXAMPLE :<br />
SUPPLY FOR A ROAD LIGHTING « LV/<strong>TIT</strong> » INSTALLATION<br />
PROJECT :<br />
In the following section, by means of an example we show how to determine rapidly the main sections constituting<br />
a preliminary study for a road lighting project using <strong>TIT</strong> transmission voltage.<br />
We draw the reader’s attention to the need to check or further specify the results obtained using the method set out<br />
below. This is because, apart from the approximate nature of this example, it is not intended to provide an answer<br />
for every situation or for every special case that may arise.<br />
The aim of the project we have used in this example is to define the power supply for road lighting of a road.<br />
Determination of the basis for calculation :<br />
The calculations are to be performed on the basis of the information to be supplied below :<br />
Number of power consumers and type : the installation comprises one lighting pole every 35 m, each<br />
fitted with two 250W high pressure sodium lamps.<br />
<strong>Installation</strong> of the lighting poles : The lighting poles are set up in the central reservation.<br />
Network length : The total length of the installation is 4 km.<br />
Station location : The station is located in the middle of the installation.<br />
Supplied voltage level : Three phase 400 V<br />
<strong>Installation</strong> conditions : Maximum ambient temperature 40°C<br />
Altitude less than 1000 meters<br />
Internal installation<br />
Operating principle :<br />
This substation will be supplied from a low voltage three phase 400 V power source, via the mains<br />
network, and will transform this voltage into a transmission voltage to be determined.<br />
STEP 1 : Determination of the network’s rating power :<br />
Determination of number of the lamps :<br />
The installation’s power is determined by the number and type of the lamps used, whose mean characteristics<br />
are described in guide C 17 205.<br />
Application :<br />
Number of lamps : 230<br />
Type and power : 250 W HPS<br />
Determination of the road lighting transformers’ power :<br />
Their power depends on the number of lamps powered by the network transformer.<br />
The transformers are used in conformity with standard NFC 52-410, which limits their use to 0.8x NP where<br />
NP is the nominal power.<br />
12
As a rule we will use transformers with :<br />
3 kVA in exchangers where the lamps will be distributed in all directions.<br />
5 kVA for the current sections.<br />
10 kVA for the pole power supplies.<br />
Other power supplies available according to use.<br />
The number of lamps supplied by a transformer is given in our table « Number of lamps by transformers <strong>TIT</strong>/LV »<br />

Please refer to the transformer documentation available.<br />
STEP 5 : Determination of the MV cable cross-section<br />
The choice of cable cross-section depends on the power and length of the network.<br />
The length is basically limited by the line drop.<br />
Protection is ensured by choosing a protection.<br />
The cross-section is given in appendix « MV cable cross section determination », which takes into account a<br />
maximum MV line drop of 2%, compatible with the total limit of 6% for MV and LV.<br />

The main transformer’s power must be at least equal to the sum of the nominal powers of the road lighting<br />
transformers, supplied downstream (NFC 17-200).<br />
We will choose a standard power, chosen in the range : 25, 50, 63, 80, 100, 125, or 160 kVA<br />
Application :<br />
In order to have an extension possibility, the retained power is 125 kVA.<br />
15
The substation will be equipped with :<br />
A LV counting table.<br />
A step-up set protection and control table.<br />
A power transformer, three-two phases, 400 V/3200 V with a 125 kVA power rating.<br />
The different features that constitute the protection table are determined depending on the transformer’s<br />
characteristics and dimensioned during the definitive study.<br />
Conclusion :<br />
This fore-study enables to difine the heights conforming to NFC 17-200 et NFC 52-410 standards with respect to a<br />
global voltage drop of 6% maximum.<br />
All the features of the fore-study, will have to be confirmed by a more precise calculation, in order to also precise and<br />
confirm the values obtained.<br />
Indeed, for our application, the 3200 V cable section retained would be 10+10 mm².<br />

The power rating mentioned is the sum of the network transformers power rating. In the case of the<br />
network transformers load is reduced , we can use the sum of the power rating of the supplied lamps<br />
counting a coefficient of around 15 %.<br />
26
Way of using the power supply range graph.<br />
These graphs help you to find quickly the right solution for the supply of a single load.<br />
The graph inputs are the distances of the load and its power.<br />
With these parameters, you obtain the voltage level to use and the wire section.<br />
Example :<br />
We have several receptors to supply at 3480 meters far. Their power are respectively 10,20,30 and 50 kVA.<br />
You have to report on the graph the cross between the 10 kVA line and the 3480 meters line. It is in the area for<br />
mono 3200V with a wire section of 6 mm². This is the best solution. You can also notice that it is under the<br />
non-continuous line for mono 950V 35mm² wire section. It means this solution is technically working but<br />
economically less profitable than medium voltage. It will be use only if we absolutely want to use low voltage. As<br />
for the 20 kVA receptors, the only solution is 3200V wire section 6 mm². Then for 30 kVA, we use 10 mm² as wire<br />
section and 16 mm² for the 50 kVA receiver.<br />
Comment on the graphs.<br />
The drawing represent the technical limit for each kind of solution to respect a maximal voltage drop of %.<br />
All the area under the drawing respect this condition.<br />
The colored areas correspond to domain were the use af a solution is the more accurate.<br />
For distance shorter than 500m the graph are not valid.<br />
The non-continuous drawing represent the limit for a technically working solution but not profitable.<br />
