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