The need for reactive power compensation may change rapidly during a complete operational cycle of fast fluctuating loads such as welding machines. Conventional reactive power compensation technologies may respond too slowly. Therefore, industrial plants operating with fast fluctuating loads may face voltage variations, flicker and load unbalancing issues. Voltage variations and flicker can even disturb other facilities connected to the same bus bar. Frequent voltage variations affect productivity and product quality and the risk of machine breakdowns will rise.
The key benefits of improving power quality for industries with fast fluctuating loads include:
