Product Specification Primary Injection Test System – SMC LET4000 RD
AC Current Test Set up to 20 Ka. The LET-4000-RD is designed to perform most of the 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 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.
Direct and motor overload relay test
In general, primary tests including the complete loop, i.e., current transformer, leads, protective relay and circuit breaker
The LET-2000-RD / 2000-RDM / 4000-RD / 4000-RDM units are constructed in two units for easier transportation. The RDM version replaces the traditional adjustment knob with a pair of push buttons that control a motorized variac for up- and down- regulation, for applications where a greater distance between the control board and the actual power output connections is required.
