Voltage classes and nomenclature pdf

Voltage Classification - LV, MV and EHV AC voltages have been classified in various manners. In earlier times, there were just two categories LV and HV. As the level of voltages increases, there was a need for more levels. Low Voltage - upto V Medium Voltage - V to 35kV High Voltage - 35kV to kV Extra High Voltage - above kV. System Voltage Classes. Low voltage: A class of nominal system voltages 1, V or less Medium voltage: A class of nominal system voltages greater than 1, V but less than , V High voltage: A class of nominal system voltages equal to or greater than , V and equal to or less than , V. NEMA Nomenclature P indicates plug or receptacle P is plug R is receptacle or socket 15 indicates the current rating and standard values are: 15 amps 20 amps 30 amps 5 indicates the voltage 1 indicates VAC, ungrounded for Class II connections.

Low voltage: A class of nominal system voltages 1, V or less Medium voltage: A class of nominal system voltages greater than 1, V but less than , V High voltage: A class of nominal system voltages equal to or greater than , V and equal to or less than , V. Apr 18,  · ANSI C establishes the nominal voltage ratings and operating tolerances for Hz electric power systems above volts (steady-state voltage levels only). Its latest revision, ANSI C includes preferred voltage ratings up to and including kV maximum system voltage. However, it does not include momentary disturbances, which may be the result of, but not limited to, . NEMA Nomenclature P indicates plug or receptacle P is plug R is receptacle or socket 15 indicates the current rating and standard values are: 15 amps 20 amps 30 amps 5 indicates the voltage 1 indicates VAC, ungrounded for Class II connections.
