Line Incompatibility: The Other Side of EMC

When speaking of electromagnetic compatibility problems, the usual first thought goes in the direction of radio and television interference. But in the big field of electromagnetic compatibility, problems can also occur between different parts of an electrical distribution network. This article will report on a very unusual resonance phenomenon and a simple, practical solution. The reader might be advised that this case occurred in Europe, where other electrical codes apply, but this situation may also happen anytime in all installations with power factor correction capacitors within the U.S., even when all articles of the NEC have been properly observed.
