TEST-901 LARGE CURRENT 1000A PRIMARY CURRENT INJECTION TEST SET FOR CURRENT TRANSFORMER
LARGE CURRENT 1000A PRIMARY CURRENT INJECTION TEST SET FOR CURRENT TRANSFORMER
TEST-901 1000A 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.
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.
Primary Current Injection Test is useful for high voltage and high
current substations or circuits. It is simply flowing of rated
current in the circuit being tested.
Primary current injection test system. 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. The system consists of a control
unit and a current unit.
