Primary Injection Test Set-2000A-Portable. Rs 1.6 Lakhs/ Number. Current Injection Source - 500 … WebPrimary 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 ...
WebPrimary injection testing, as opposed to the secondary injection test, is the only way to prove correct installation and operation of the whole protection chain, as the test involves the entire circuit: current transformer primary and secondary windings, relays, trip and alarm circuits, circuit breakers, and all wiring. WebInject the current to each module of the busbar protection to check the pickup value, which should be ±5% of the normal pickup setting of the relay. 2. Pickup test of the breaker failure module if it is attached to the Busbar protection system. Inject this module with current and check the pickup value is within ±5% of the nominal pickup value.
WebConnect an ammeter to the R-phase of CT to monitor the secondary current. Connect a milli-ammeter to the earth-fault relay current coil to monitor the spill current. Inject 50% and 100% of the CT ratio through the primary bars and record spill current respectively. At the same time, record the secondary current of the R-phase respectively. WebPrimary injection is not as common as secondary injection. A 3‐phase generator (typically LV) is used to energize the substation bus and then loads are placed on each circuit to …
WebThe excellent use of the primary injection test set is to observe how the system will work when you checks the equipment with variable current loads. If the output is weak, it cannot handle a massive current and will fail. If the product is strong and can handle a large current. Call Now: +91 94774-23085. View More.
