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:
| Sl no | Name of Apparatus | Type | Specification | Qty |
| 1 | Wattmeter | |||
| 2 | Lamp | |||
| 3 | Fuse | |||
| 4 | Voltmeter | |||
| 5 | Neutral link |
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:
- Connections are made as per the connection diagram.
- Before switch on the supply the auto transformer must be in the minimum position and the loads are in off position.
- Now switch on the single phase AC supply adjust the auto transformer so that the voltmeter reading 230 V.
- Now insert the lamp load take the time taken for n revolution of the energy meter disc using stop watch.

| Sl no. | Voltage in V | Time for 5 revolves of energy meter rev. in sec | Energy consumed by the load=nx3600/t x k in KWH |
RESULT:
The given circuit is studied and single phase energy is measured using the energy meter.
