Investigation of voltage sag problem on sensitive load using ride through simulation based mitigation equipment / Azura Samrek

This report focused on voltage sag happened to industrial consumer, which Compressor proven as sensitive equipment because the load affected when voltage sag event occurred. The Ride Through Simulation tested on the 2 points at the Compressor; Control Circuit and Starter Circuit. Compressor is main equipment to the operation of manufacturing industry. By using Ride Through Simulation Technique, the Compressor (before installation Minidisc) detected and proved that the Compressor as sensitive equipment based on MS IEC 61000-4-34 standard. In this work, the Minidisc was used as mitigation equipment to Compressor to improve the Immunity Level of Compressor. This is then proving by Ride Through Simulation results. Therefore, the risk caused by voltage sags could be minimized.
