Primary Injection Test Systems
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. The objective of the test is to identify how the system operates under various levels of current load.

Primary Current Injection Sets
Protective devices such as relays, overload Coils, Circuit breakers and CTS etc. must be checked regularly to ensure that they are always ready to operate correctly, Routine current injection testing will quickly detect faulty or incorrectly adjusted protection circuits / devices & will be possible to prevent serious damage to the system. Primary injection kit is designed to operate on single phase 230/240 volts AC 50 HZ to develop smooth & continuous test current as for loading, calibrating, and testing of CTS, Bimetal Relays, Protection Relays etc. The test set gives high current output at low cost and with inherent safety. The primary current injection testing checks all parts of the protection system by injecting current down the cable / bus bars. The application of the primary current injection sets is to ascertain the current carrying capacity of any Conductor, insulator, connector or calibration of CTS / Bi-metallic relays etc.

Primary Current Injection Testers
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.
