A new watt-hour meter

To meet the demand for sustained accuracy in watt-hour meters and for adaptability to service requirements, the meter described in this paper has been produced. It offers simplicity and interchangeability, light weight, high accuracy over a wide range of load, and convenience of adjustment, and features an improved overload compensator, a new form of full load adjustment, and a new form of combined open-potential-coil indicator and balance adjustment for polyphase meters.
