Study of calibration of Single phase Energy meter of 5 A capacity with 750 revolutions / KWH with unity power factor. This consists of calibration measurement of Known energy meter with unknown energy meter. Two energy meters are supplied with this trainer. One of them is known to be calibrated and the other TO BE calibrated to determine % of deviation. By this method percentage deviation of an Unknown energy meter is studied.

(a) Energy meter ( WITH VISIBLE TRANSPARENT CASE FOR VIEWING ALL THE MOVING PARTS)– 2 Nos
(b) Digital voltmeter to monitor the incoming line voltage,
(c) Digital Ammeter to measure the amount of current passing thought the energy meter.
(d) Stopwatch used to measure duration of energy consumed per Unit time.
(e) Necessary power supplies to conduct the experiment for the measurement of energy consumption per unit time. All assembled in a cabinet with all the terminals brought out for interconnecting and for the purpose of measurement.

By connecting an external variable lamp load and using stop watch, the energy consumed per unit time (KWH) can be measured.

Lamp load capable of providing 5A OR resistive load of 10A.
