Energy Meter Calibration Services in Bangalore (1 service providers available)

An electricity meter or a watt-hour meter measures the electrical energy passing through the meter and may be single phase or poly phase. The calibration assures that the measurement errors can be kept within the desired limits. By the regular calibration at SP the stability of the meter will be monitored closely. The normal calibration method is to generate the desired power levels, and to compare the measured energy of the unit under test with the power measured by a reference system, usually by comparing the frequency of pulse outputs.
