The Kilowatt Hour (Kh), disk revolutions, and time in seconds are needed to calculate the Watts on an Electromechanical Meter. Compare the Source measurement to an Electromechanical Meter Note the reading on the Solid State Meter, either remotely or from a hand held device, and compare this measurement to the Watts or Kilowatts calculated from the source. Compare the Source measurement to a Solid State Meter ![]() With the calculated Kilowatts, you can now review the readings on the revenue meter for comparison. Knowing the Voltage is approximately 120V, the Kilowatts can be quickly calculated as follows: (28 + 32) x 120 = 7200 Watts To provide an example, side A of the feed is 28 Amps, and side B of the feed is 32 Amps. With this understanding, it is acceptable to assume the measurement by using the nominal voltage if it is not possible to take a direct voltage reading with a live-line Voltmeter. The ANSI C84.1 standard states voltage is to be within +/- 5%. The nominal voltage for a single phase service in North America is 240 VAC Line to Line or 120 VAC Line to Neutral. Or, for an underground service, a quick measurement taken at the pad mount transformer. On an overhead service, a quick amp measurement can be taken with a live-line ammeter on the two power leads going to the customer’s weather head. How to calculate Kilowatts: (Amps x Volts)/1000 = Kilowattsįirst, take a current reading at the service entrance. How to calculate Wattage: Amps x Volts = Watts* ![]() This conversion allows for a quick field verification to identify any inefficient loading. Because the revenue meter displays the load in either Watts or Kilowatts, the Amp reading taken at the source will need to be converted. When out in the field to investigate, utility personnel should determine if there is a discrepancy from the source to the revenue meter. Revenue protection professionals use the input of various sources to point them toward locations where there is suspicion of power diversion.
