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

200A-3PH/ED Specification

Main Output

The units have three independently controlled outputs, one for
each phase. The output is switched on and off by illuminated
pushbuttons, and the current is set using the three control knobs
on the front panel. All ranges are continuously variable from
zero.

Range Continuous 5 minutes 1 minute

5V 50A 100A 200A
The above intermittent on times must be followed by an off time
of 15 minutes, and are based on an ambient temperature of 25°C.

Auxiliary AC Outputs

A switched, isolated auxiliary 240V 50mA AC supply is available
to power auxiliary control circuits. The output is protected by a
fuse.

Metering

The output on the 200A-3PH/ED is metered by a digital true
RMS system with a 3.5 digit LED display. The range for each
channel is independently selected for each channel by a switch
on the front panel.

Range Resolution Trip Current Accuracy

10A 0.01A 11.5A ±0.6% rdg+6d

An electronic current trip is automatically set to 115% of full scale
of the selected metering range to protect the device under test.

Timing System

The timing system on the 200A-3PH/ED is very flexible, allowing
a wide range of protective devices to be timed.

Range 0-999.999s
Resolution 1ms
Accuracy 0.01% rdg +1d (all except current operated mode)

0.01% rdg +3d (current operated mode)
The contact circuit has an open circuit voltage of 24Vdc and a

short circuit current of 300mA. The contacts may be connected
to volt-free contacts or contacts connected to a DC voltage
system (220Vdc maximum).

The following functions are provided:

Mode Timer Start Timer Stop

Normally Open Press ‘ON’ Contact closes
Normally Closed Press ‘ON’ Contact opens
Current operated Current > 20% Current < 20%
of range of range
Off Timer inoperative Timer inoperative

The output is automatically switched off at the end of the test to
safeguard the relay under test.

Protection and Safety

The 200A-3PH/ED is protected by electronic over current trips on
the outputs, fuses on the contact input, the mains input and
regulators.

The auxiliary AC output is fuse protected. An earth terminal is
provided for connection to a local earth.

The unit is designed to comply with BSEN61010, and is CE
marked.

Optional Delta-Star Supply Transformer

The optional delta-star supply transformer allows operation from
115V, 230V, 400V, and 440V 3 wire (delta) supplies. The input
voltage is selected by a switch on the unit. An auxiliary single
phase output is also provided to supply power to a DVS3 voltage
source.
