ENERGY METER

Theory

* Energy meter is an instri rument nt whic h measures
electr 1 as watt-hour
er are

and commercial

installation. Electrical energy is measured in kilo
watt-hours (kWh) by this energy meter.

Construction: Driving system

Moving system

These two forces constitute a deflecting
torque.

Braking system

The braking system consists of a permanent

magnet calle

1 brake magnet. It is placed r

the edge of the disc as the disc rotates in the
à ie Magnet on current

The ‘braking torque is | proportional to the
speed of the disc.

Registering system
