A word of caution, there are many interference sources, and many frequencys of emission. Don't put all your eggs in this basket. Emission sources can be continuous or random (i.e. only on windy days), an arcing source produces broadband emissions. A car radio tuned to a low noise part of the AM band when driving or an inexpensive AM radio is a good detector, the extended antenna is a safety concern but will point (null) at the source.
