Failures could increase the chance of an arc flash hazard and require more downtime for repairs.
Motors
Motors are the most common source of power used by pumping systems. This technology is heavily regulated. Pumps by themselves are not variable speed, an option that many systems need to operate with peaks and ebbs during the run cycle, such as power generation. The addition of a variable frequency drive (VFD) gives it that capability.
Motors and drives work together in various ways.
Ground fault detectors provide economic efficiency by improving operational availability.
Early inspection revealed a winding fault in one municipal utility district.
This newer technology excels at the high duty cycle, low speed applications that can cause problems with other motors.
Use a systems approach and updated technology for better operation.
Power quality and grounding are a couple of things to consider for optimal motor and system operation.
Start with NEMA standards, then consider other conditions.
