TEST-902 2000A small cart primary current injection test system for testing of protective relay equipment and circuit breakers
2000A small cart primary current injection test system for testing of protective relay equipment and circuit breakers
TEST-902 2000A small cart primary current injection test system adopts ARM chip to control the output process and large capacity of toroidal transformer. It is equipped with LCD screen display current meter, also showed primary current value, secondary current value, turn ratio and the action time. Aluminum alloy body with PC panel component the shell.
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
