Single Phase Induction Type Energy Meter

Single Phase Induction Type Energy Meter Points : Single Phase Induction Type Energy Meter These metes are the most common for most common form of a.c. meters, found in every day domestic and industrial installations. These meters measure electrical energy in Kilo-Watt-hours. The working principle of these instruments is the same as that of the induction type wattmeters. The construction of two is similar except that the control spring and the pointer of the wattmeter are replaced, in the case of watt -hour meter, by a break magnet and by a spindle of the meter. The brake magnet induces eddy currents in the disc which revolves continuously instead of rotating through only a fraction of a revolution as in the case of wattmeters.
