Primary Injection Relay Test Equipment LET-1000-RD
The LET-1000-RD is designed to perform most of the primary tests that are necessary in substations commissioning. It allows to perform with sufficient power, all the primary current injections to test the proper function and wiring of all the elements that compose the protection and measuring section in a substation. The regulation system is based on a continuously variable autotransformer (Variac) that supplies to a power transformer that delivers the high current outputs and isolate the main supply from the load. A built-in ammeter and a timer gives the information about the current value and the operation time of the relay or breaker under test. APPLICATIONS Direct and motor overload relay test. In general, primary tests including the complete loop, i.e., current transformer, leads, protective relay and circuit breaker. CHARACTERISTICS Permanent current up to 1000 A, 2 KVA in 3 Ranges. Built in digital ammeter 0.5% accuracy. Built in digital timer resolution 1 ms. Thermal and shortcircuit protection.
