TEST-901 CIRCUIT BREAKER OF 1000A PRIMARY CURRENT INJECTION TEST KIT WITH TIMER
Manufacturer of PRIMARY INJECTION KIT - primary injection test set, AC Current Tester, Primary Current Injection Test Set and Current Transformer Test Set offered by GFUVE Electronics company in China Beijing.
TEST-901 primary current injection test kit 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.
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system.
The primary current injection method is usually the preferred test method because it includes the current sensors, wiring, and the current conduction path in the circuit breaker with the test. However, this method has one disadvantage in that it will not always detect sensor wiring and polarity problems.
