Atec T-R-200A-3PH-ED - Manual

200A-3PH/ED
T&R Test Equipment is a market leader in the field of current
injection equipment. The range includes single phase units
with 100A-6000A output capability and three phase systems
up to 200A. All have true RMS metering, a flexible timing
system, and an easy to understand user interface.
The 200A-3PH/ED test system provides commissioning and
maintenance engineers with a compact, portable and flexible
system for the testing and timing of protective relays, circuit
breakers and thermal overloads. The unit is equally at home
testing solid state or electro-magnetic relays, and has a rating
suitable for testing thermal trips.
The 200A-3PH/ED has independent true rms digital metering
for each output with independently selectable ranges.
The outputs are isolated and independently variable and
allow the injection of currents up to 200A. The outputs are
protected by electronic over-current trips and fuses.
The timing system on the 200A-3PH/ED is flexible and
exceptionally easy to use, allowing trip times to be measured
to a high degree of accuracy. Units with auxiliary contacts
may be timed using the NC or NO timer modes, and devices
with no auxiliary contacts may be timed using the current
operated mode.
The unit is ideal for testing the following devices:
•
Over and under current relays
•
IDMT relays
•
Thermal overloads
•
Magnetic circuit breakers
The unit may also be used in conjunction with the DVS3
digital voltage source to test protection systems requiring
three voltages and three currents. Protection that may be
tested in conjunction with the DVS3 includes:
•
Directional relays
•
Distance protection
•
Power relays and transducers
