Electrical Test Equipment For Substation & Protection Relay Testing

Products: Primary Injection: LET-400

                                                Primary Current Injection Test Set

 

The LET-400 is designed to perform 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.
