In the energy meter testing, the actual registration of energy (by the meter) is verified against known standard values at various loads and power factors. The energy meter testing helps in providing suitable adjustments in the m…
Trivector meter is used to measure the kVAh and kVA of maximum demand. It consists of two meters whose discs are coupled with a special kind of summator through a complicated gearing system. Among the two meters, one is an energy…
It is essential that the electrical energy supplied by the electrical power suppliers must be sufficient enough for operating the various equipment of their consumers. In order to achieve this, the generation and distribution sys…
Energy meter calibration is a process required to determine and reduce the error when the energy is measured. The errors in the energy meter can be caused by different sources like voltage transformers, current transformers error…
Creeping in Energy Meter : Generally, the energy meter is designed to measure the energy consumption of load connected to it i.e., the energy meter disc should rotate when there is a flow of load current in the current coil. Whe…
The various types of errors in an energy meter are caused by the driving system and braking system. Errors Caused by Driving System : Errors due to the incorrect magnitude of fluxes. These are mainly due to variations in supply…
In the last article, we have seen about single-phase induction type energy meter that can be used to measure the energy consumed in the single-phase circuit. In order to measure the energy consumption of a three-phase circuit thr…
An electrical measuring instrument used to measure the energy consumption of a load is called an Energy Meter. The measurement of electrical energy consumption by the various domestic and industrial loads is very important from t…
