TEST-901 High voltage current transformer ratio primary current injection test set
Product Description
TEST-901 High Precision Large Current Generator use ARM chip to control the output process and large capacity of toroidal transformer, and equipped with LCD screen display current meter, also showed primary current value, second current value, turn ratio and the action time. Equipped with aluminum alloy chassis, PC panel, which has the advantages of beautiful appearance, large output capacity, small volume, light weight etc. High Precision Large Current Generator is mainly applied to test CT turn ratio in the power system and the contact resistance etc, which need large current.
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
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.
