PSC Staff Report: The Phase II Stray Voltage Testing Protocol (February 1999) A stray voltage testing protocol is presented that has been tried and proven for the documentation of comprehensive, multi-source stray voltage testing. There are suggested forms for data acquisition as well as a discussion of the methodology of data collection and interpretation. The Phase II protocol should be considered a minimum test protocol for a follow-up stray voltage investigation where the amount and all sources of stray voltage are to be determined.
