Primary & Secondary Injection Test Sets

Primary Injection Test Sets for High Current applications

Testing the primary side of substation equipment requires a current/voltage injection technology that can  simulate primary loads. Primary test systems can be used for various substation testing, including circuit breaker and re-closer testing, relay testing, ground grid integrity verification, transformer saturation analysis, burden and ratio measurement, and more.

Secondary Injection Test System

The purpose of secondary injection testing is to verify that the correct operation of the protection scheme from the relay input terminals onwards is functioning correctly with the settings specified. Secondary protection system consists of auxiliary relays, protective relays, protection circuits, metering devices, communications and control systems, low-voltage devices etc.
