Single Phase Energy Measurement using Energy Meter

12 – SINGLE PHASE ENERGY MEASUREMENT USING ENERGY METER

Aim :

To measure single phase energy consumed by a load use of energy meter.

APPARATUS REQUIRED:      

THEORY:

      Let the time taken for ‘n’ revolution of the energy meter‘t’ second

         No of revolutions per hours = n/ (t/3600)

         Energy consumed by the load = (n x 3600)/ (t x k)

Where k is equal to energy meter constant in revolution per KWH

PROCEDURE:

1. Connections are made as per the connection diagram.
2. Before switch on the supply the auto transformer must be in the minimum position and the loads are in off position.
3. Now switch on the single phase AC supply adjust the auto transformer so that the voltmeter reading 230 V.
4. Now insert the lamp load take the time taken for n revolution of the energy meter disc using stop watch.
