TEST-901 Primary Current and Secondary Current Injection Test Seystem of
High Voltage Circuit Breaker
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.
