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.
