Calibration of energy meter can be obtained graphically by plotting the percentage error against load current I. This graphical representation of the calibration process is called a calibration error. At the initial stage, the load current I is zero, and hence no % error because the energies E and E T are zero.
Calibration of Single Phase Energy Meter. First of all reading of energy meter is brought at zero. Now the total load of 10 lamps is operated for one hour (by using a stopwatch). After 1 hour, the energy meter should show consumption of 1unit. (i.e., 1 kWh). If not so, the meter is adjusted accordingly.
%Eror = (E−ET ET) ×100 % E r o r = (E − E T E T) × 100 The energy meter calibration can be obtained by the use of a graph. This is made possible by plotting a graph of percentage errors against the current values, I. The graphical representation of the energy meter calibration is known as the calibration error.
The energy meter undergoes calibration, too. This is the process used to determine and eliminate errors during energy measurement. Some of the factors that inject errors in an energy meter are current errors caused by phase angle, voltage transformers, and errors caused by crystal oscillators.
The graphical representation of the energy meter calibration is known as the calibration error. Initially, the load current is valued at zero, and therefore, there is no percentage error because the values of the energies E and E T are zero. The figure below is an example of the energy meter calibration curve. Figure 2. The Calibration Curve Graph.
An electric energy meter is designed to have specified characteristics and parameter constants that deliver necessary information about disc revolution counts and energy measured in joules. These characteristics and parameter constants are specified by the energy meter manufacturers. Below is the setup that makes meter calibration successful.

In this topic, you study Calibration of Energy Meter – Definition, Procedure & Diagram. By calibration of the energy meter, we mean that the meter should read 1 kWh if 1000 W (1 kW) load is operated for an hour. Calibration of Single Phase Energy Meter (By Direct Loading Method)
Energy Meter Calibration Procedure. Below is a step-by-step procedure used to calibrate the energy meters. Connection your circuit as per the circuit drawn in figure 1 above. Check the meter-rated voltage and supply it to the meter that is at no load initially.
The calibration coefficients are easy to calculate, and by applying them during normal power meter operation (after the power meter is calibrated) both the active and reactive powers/energies will be measured accurately by the power meter. You can use such power meter calibration for billing purposes.
