TEST-905 5000A Circuit Breaker Testing Primary Current Injection Test System

primary current injection test system

TEST-905 5000A primary current injection test system adopts 32bit ARM chip to control the output process and large capacity of toroidal transformer. It can output up to 5500A, timer from 0 to 999.999s, and equipped with LCD screen display ammeter, also showed primary current value, secondary current value, current transformer turn ratio and circuit breaker of the action time. Aluminum alloy body with PC panel component the shell. TEST-905 primary current injection test equipment is mainly applied to test CT turn ratio and polarity in the power system, the contact resistance, protection relay, low voltage & high voltage circuit breaker protection test and high voltage generator test etc, which need large current on-site or in the lab. This primary injection test equipment can be used as cable temperature rise testing equipment.
