Multiplying Factors and Monthly Electric Bills

11/30/2009 1:30 AM

I wanted to know as to whether we got to use the multiplying factors to calculate the total unit consumption if a CT meter is used. This is in case of a monthly electric bill?

Hi guest,

All digital meters are shown direct readings, hence there is no need multiply with the multiplying factor.

If the meter is anologue, the reaings are need to multiply with the multiplying factors. Hope you got the point

The multiplying factor is normally specified by the meter manufacturer and is usually displayed on the meter name plate. However, the multiplying factor may or may not be a direct reduction of the CT ratio. Sometimes, it also includes a certain number of rotations of the disc (in case of electromechanical type meters) per kWh.
