How to Eliminate Voltage Sag in High-Power Three-Phase Motors
Voltage sag creates a nightmare for anyone running high-power three-phase motors. I've experienced this firsthand when a 250-kilowatt motor in our facility would occasionally dip below its optimal voltage level, causing all sorts of operational hiccups. To give you some context, a voltage sag typically occurs when the voltage drops to between 10% to 90% …
