SMC LET-400-RD Primary Current Injection Test Set

<p>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. <br /> 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.<br /> <br /> APPLICATIONS<br /> <br /> - Test of the I/T curve in primary current relays test.<br /> - Primary injection tests.<br /> - Test of measurement and protection transformers.<br /> - In general, primary injection tests including the complete loop, such as current transformer cables, protective relays, and circuit breakers. <br /> <br /> CHARACTERISTICS<br /> <br /> - Permanent current up to 400A 1KVA in 4 Ranges.<br /> - Built in digital ammeter 0.5% accuracy.<br /> - Built in digital timer resolution 1 ms.<br /> - Thermal and shortcircuit protection.<br /> &nbsp;</p>
