TEST-902 primary current injection test set 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.
