EuroSMC LET-4000-RDM Primary Current Injection Test Set


The LET-4000-RDM is designed to perform most 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 motorized auto-transformer (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.
