at which the supply authorities deliver power to the consumer is :
240 V, 50 Hz, 4 wire
240 V, 50 Hz, 2 wire
415 V, 50 Hz, 4 wire
415 V, 50 Hz, 3 wire
415 V, 50 Hz, 4 wire
The standard voltage for three phase
at which supply authorities deliver power to the consumer is V, 50 Hz, 4 wire.
Hence, the correct option is (C).
