Harmonics Recordings

Electrical equipment will often malfunction or have other abnormalities or “ghosts in the machine” when excessive harmonics are present in an electrical system if not properly designed or rated for them. Although there are standards for all electrical equipment to function adequately with some level of harmonics, the emission of voltage and current harmonics from power electronic devices causes extra stress of equipment.

Harmonics have been around since the first AC generator went online more than 100 years ago, however early equipment was not sensitive enough to be effected by them in large. If your facility is experiencing electrical malfunction that can’t be explained, Southwest Energy Systems, LLC can perform a power systems study by placing highly accurate, high speed recording instruments on your critical circuits to help assess the problem. We’ll help identify or confirm the problem, establish where the source of the problem may occur and recommend solutions to meet your needs and budget.
