Three Phase Secondary Current Injection Kit 200A-3PH MK2

The  Secondary Current Injection test set 200A-3PH Mk2 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-mechanical relays, and has a rating suitable for testing thermal trips.

The 200A-3PH MK2 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 Mk2 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 units 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

Main Output

The units have three independently controlled outputs, one for each phase. The output is switched on and off by illuminated push buttons, 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
0-5V 50A 50A 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.

Digital 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.

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

The unit is must be supplied by a 400V±10% 50/60Hz 3 phase 3300VA Max. The optional delta-star supply transformer allows the 400V unit to operate from other supply voltages.

A delta-star transformer is available as an optional accessory for operation from a 3 wire supply.
Temperature Range:

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

Protection and Safety

The 200A-3PH mk2 Secondary Current Injection 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 on both units. An earth terminal is provided for connection to a local earth.

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