Electrical energy can be converted into a variety of energy. Such as: electric furnace is converted into thermal energy, by the motor into mechanical energy, is converted into light power transformers by the lamp and the like. In these transformations in energy consumption for active energy. The record of this energy meter for active energy meter.
Reactive power meter
Electrical theory tells us that some electrical equipment for energy conversion when served to establish a transition environment, such as: motors, transformers, etc. must first establish a magnetic field in order to make energy conversion, and some electrical device is first made to establish an electric field energy conversion. The establishment of magnetic and electric power are required reactive energy. The record of this power meter for reactive energy meter. Reactive energy in the electrical device itself is not consume energy, but will produce reactive current in the electrical circuit, Air circuit breaker the current will produce a certain loss in the line. Reactive power meter is specifically record this loss, usually only the larger power unit before the installation of such meters.
