T3...-73-M..<br />
APPLICATION<br />
The three-phase three-element active energy meter with programmable<br />
electronic maximum demand indicator (MDI) is designed for<br />
measurement and registration of electric energy and power to single<br />
or double-tariff registers. It is used for direct connection or via measuring<br />
transformers to three-phase four-wire system with balanced<br />
and unbalanced load.<br />
It is suitable for direct reading or reading with using multiplying factors.<br />
All the data can be read-out visually, or automatically by means of<br />
HHU-Hand Held Unit or PC with corresponding programme software.<br />
RATINGS<br />
The measuring and technical qualities of the meter T3.. comply with<br />
the following International Electrotechnical Commission Publications<br />
(EN 60 521, IEC 521) and Germany Standard (VDE 0418). The MDI<br />
electro-technical qualities comply with IEC 211, IEC 1036. Their construction<br />
and mechanical dimensions comply with DIN 43857 and all<br />
respective DIN dimensional standards.<br />
The accuracy class is 2. The meters connected via instrument transformers<br />
can be also class 1.<br />
GENERAL CHARACTERISTICS:<br />
The meter is an electromechanical type, with incorporated electronic<br />
microprocessor - based, programmable MDI. It is designed as simply<br />
replaceable module which enables the access to testing and calibration<br />
spots of induction measuring system. The meter measuring system<br />
is provided with mechanical parts for fixing of MDI, a special version<br />
of the rotor with markers for detection of revolutions, and voltage<br />
electromagnets with additional winding for MDI power supply.<br />
Basic functions of meter:<br />
– measurement and registration of electric energy<br />
– measurement and registration of max. average demand<br />
– registration of previous maximums<br />
– registration of cumulative maximums<br />
– indication of function errors<br />
Display – 12 digit LCD - with back light<br />
Keyboard (Push-buttons)<br />
– CALL key button (call-up sequence of the meter display)<br />
– RESET key button (resetting of MDI into<br />
initial position represents the end of<br />
billing period)<br />
Communication port<br />
Optical port for meter reading, using<br />
magnetically attached optical head.<br />
Automatic read-out is performed in<br />
compliance with IEC 1107 recommendation,<br />
“Data exchange for meter-reading,<br />
tariff and load control. Direct local<br />
data exchange."<br />
Data transmission is performed via<br />
two-directional IR optical interface,<br />
which corresponds to C mode. Protection<br />
of total data block complies<br />
with DIN 66219 standard.<br />
