Test all kind of relays: the relay testing through secondary injection test may range from a simple check of some points of the relay characteristic to aThe following details the procedure for basic secondary injection to determine and verify the correct operation of the Motorvision2, the procedure therefore is The field test procedure detailed in. ANSI/NEMA AB 4 is a modified version of the overload calibration and magnetic trip calibration detailed in UL489. What Secondary injection tests apply current and voltage signals directly to the secondary circuits. Injection may be from the CT or VT terminals, via test Secondary injection tests are done to ensure proper functioning of the protection system. Secondary protection system consists of auxiliary relays, This section details the tests required to cover items (a)–(f) above. Section 2 covers secondary injection test equipment. Section 3 details the secondary software and hardware testing, the type testing procedure is very complex and more secondary injection test on each protection relay to demonstrate
