Features Permanent current up to 1000 A, 5KVA Max current output up to 1100A. Built-in digital ammeter 0.5% accuracy. Built-in digital timer resolution 1 ms (Optional). Made up of two units, control and power unit Thermal and short-circuit protection. With 6m length 1000A heavy current test cable With contact Applications TEST-901 primary current injection test set adopts ARM Chip to control its output process and large capacity of toroidal transformers. It is equipped with LCD display and current meter; it can show primary current value, second current value, turn ratio and the action time. Packing is used as aluminum alloy body with PC panel. TEST-901 is mainly applied to CT turn ratio testing in the power system and contact resistance test which need large current. Circuit Breaker Test Current Transformer Test Resistance Test Power Transformer Test Primary current injection test TEST-901 primary current injection test system is a necessary equipment in all walks of life in electrical commissioning needs large current place, used in power plants, substations, electrical manufacturers and scientific research, laboratory and other units, belonging to short-term or intermittent working system, It has a small size, light weight, good performance, easy to use and maintenance features.
