Title: Watt Hour Meter Assembling Plant
Keywords: Watt Hour Meter
Meter
Issue Date: Jan-1979
Publisher: United Nations Industrial Development Organization
Abstract: The watt hour meter is an instrument used in a house or plant to measure electric power. The driving force caused by the magnetic field and turning force, which are generated by electric current, is represented by revolutions of a disc. The number of revolutions is transmitted by connecting its revolving axis to a gear. Such a measuring instrument should be reliable and stable with a minimum loss of electricity as well as possibility of mass production at reasonable prices. This measuring instrument should also have excellent characteristics against possible errors due to variations in current, voltage, temperature and frequency. Its specifications include single-phase 2- wire, single-phase 3-wire, three-phase 3-wire, three phase 4-wire, etc. for use both in houses and industries.
