T&R 200A-3PH Mk4 Three Phase Current Injection Test Set
- 3 independently controlled outputs, one for each phase
- Features a digital true RMS system with a 3.5 digit LED display
- Flexible timing system, allowing a wide range of protective devices to be timed
- Protected by electronic over current trips on the outputs, fuses on the contact input, the mains input and regulators
- Designed to comply with BSEN61010 and CE marked
The T&R 200A-3PH Mk4 Secondary Current Injection 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-mechanical relays, and has a rating suitable for testing thermal trips.
The 200A-3PH Mk4 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 Mk4 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
