Meters for Measurement of Energy

Meters for Measurement of Energy and Other Electrical Quantities, Meters are needed to be installed at several points of the Distribution System including the substation equipment and the consumer end. They are needed for correct recording of electrical quantities for operational and safety reasons as well as energy accounting. The meters installed at the interface points of generation-transmission and transmission-distribution are known as interface meters. Meters installed at consumer premises through the utility are called consumer meters.

The Central Electricity Authority regulations on Installation and Operation of Meters provide for the type, ownership, standards,  location, installation, accuracy class,  operation, testing and maintenance, sealing, access,  safety, meter reading and recording, discrepancies or meter failure anti tampering features, calibration, quality assurance or periodical testing of meters, further meters and adoption of latest technologies in respect of the following meters for correct accounting, billing and audit of electricity:

1. Interface meter,

2. Consumer meter, and

3. Energy accounting and audit meter.

It is significant to remember that these regulations make the use of static meters mandatory for new consumers.
