The following step-by-step procedure is intended to help farmers, and others who arent necessarily experts in electricity, determine if there may be a stray voltage problem on the farm. It is desirable to make these measurements during periods when the electrical load on the farm is high (i.e., during or near time of milking cows). Establishing of an isolated reference ground and connecting the voltmeter leads to the reference ground and barn service entrance ground as described in Standardized Measurements in Chapter 18 will be needed.
