TEST-902 Low Voltage Circuit Breakers & Relay of 2000A Primary and Secondary Current Injection Tester

TEST-902 Primary Current Injection Tester could simultaneously display primary current, secondary current and turn ratio. It is mainly suited for CT turn ratio and contact resistance tests of power system and other occasions needed high current test.
2000A Primary Current Injection Tester of TEST-902 is applied in power system for circuit breaker test, protection system test and current transformer test. The tester generates 2000A high current from power supply to simulate the rated current or fault current in the primary circuit of power equipment.

TEST-902 is mainly applied to test CT turn ratio in the power system and the contact resistance etc, which need large current.

This powerful test system is designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the turns ratio of current transformers and for other applications that require high variable currents.

The system consists of a control unit and a current unit. The two parts are portable, and TEST-902 can be quickly assembled and connected.

The control unit has many advanced features – a powerful measurement section for example, that can display turns ratio as well as time, voltage and current. A second measurement channel can be used to test an additional current or voltage. Current transformer turns ratio, impedance, power, power factor (cos φ) and phase angle are calculated and shown in the display. Current and voltage can be presented as percentages of nominal value. The fast-acting hold function freezes short-duration readings on the digital display when the voltage or contact signal arrives at the stop input, the object under test interrupts the current or injection is stopped.

FEATURES

• Most advanced primary current injection test system to simplify all types of switchgear and CT commissioning, ground grid, circuit breaker testing and more
• Modular design to permit optimal user configuration of output current vs. unit size
• Compact transport cart facilitates portability into switchgear rooms with limited space
• Unique I/30 function allows the current to be pre-set using low current to prevent test sample heating, thus eliminating corruption of test result
