Testing for Stray Voltage
Testing for stray voltage is easy and is an un-ambiguous way of determining if the problem exists. You can determine if you have stray voltage with an inexpensive AC Voltmeter. If you do not measure a voltage using the following procedure, then you do not have a stray voltage problem. If you find that you do have a stray voltage problem, then you need to call in an engineer that to determine the cause and implement corrective action.
Use the following test procedure to verify that you have a stray voltage problem. You will need an AC Voltmeter, 2 eh 1000 ohm resistors of any wattage, a 2 prong banana jack, a long piece of insulated wire to extend the meter leads and a metal rod.. The best time to test is between 17:00 and 19:00 hours in the evening. The tests should be made with as much equipment as possible turned on to cause the maximum load on the farms electrical system.
Very low or readings less than 0.1 volt indicate that there is not a stray voltage problem. Readings between 0.1 and 0.5 may indicate a problem and need to be investigated further. Readings above 0.5 volt indicate that you definitely have a problem.
If you find that you have a Stray Voltage problem you will need a professional to perform further tests and to make a detailed evaluation of your electrical system. Call us at 952/544-6079 if you have any questions or if you would like us to assist you.
