TEST-901 primary current injection test system 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 such as a circuit breaker.
High-current generator 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.
