TEST-903 electrical 3000A primary current injection test equipment

current injection test equipment

TEST-903 3000A primary current injection test equipment adopts 32bit ARM chip to control the output process and large capacity of toroidal transformer. It can output up to 3300A, timer from 0 to 999.999s, and equipped with LCD screen display current meter, 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-903 primary 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.
