T&R Test Equipment is a market leader in the field of
current injection equipment. The range includes
single phase units with 50 Amp
up to 6000 Amps output capability and three-phase
systems up to 200 Amp. 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 testing 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 200
Amps. 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.
