standard voltage definition

standard voltage means in the case of a low-voltage single phase supply, a voltage of 240 volts between phase and neutral and, in case of a 3-phase supply, 415 volts between phases, or in the case of any high voltage supply, the voltage at which the Authority has contracted to give supply;
standard voltage means the phase voltage of 230V measured between a phase conductor and the neutral conductor, or a line voltage of √3 x 230V measured between phase conductors;
standard voltage means the voltage at which the supply is declared to be provided by the Authority at the consumer’s supply terminals;
