![]() ![]() This condition of Single Phasing is usually caused when:. It occurs when one of the 3 phase circuits in a three-phase motor is opened hence the remaining circuits carry excess current. Single phasing is a power supply-related electrical fault in case of an induction motor.

Related Reading: Electric Propulsion System For ShipsĪ 3 phase motor of 440V is, in general, the standard frame, squirrel cage induction type designed for AC 440v 3 phase of 60 Hz. have 3 phase motors attached to them which run one or the other main or auxiliary system for them. The critical machinery such as steering gear, main engine, generator, boiler etc. The ship is fitted with hundreds of motor,s which are responsible for running different pumps, machinery, and systems. ![]() ![]() The loss of current through one of these phase supplies is described as single phasing. Once these three-phase motors are started, they will continue to run even if one of the three-phase supply lines gets disconnected. For proper working of any 3 phase induction motor, it must be connected to a 3 phase alternating current (ac) power supply of rated voltage and load. ![]()
