Why Three Phase Diesel Generator Loses Phase?

    A three-phase diesel generator is a new type of power generation equipment, with a lightweight design, reliable quality and a wide range of applications. Many customers feedback that the three-phase diesel generator sometimes lacks motor phase during its use. What is the reason for the phenomenon? The reason for the phase loss of the three-phase diesel generator motor is that the power supply line (usually a contactor or a circuit breaker) does not supply the three-phase voltage to the motor at the same time, or the line is disconnected. The phenomenon is that if the motor can rotate at no-load, it will instantly heat up and hum and the rotation will be weak; when it is overloaded, it will just hum and instantly heat up. If the power is not turned off in time, the motor will be burned. For a three-phase induction motor, the normal operation should be three proportional AC currents flow into the three proportional stator windings to produce a circular rotating magnetic field. When the three-phase current is missing one phase, the motor will appear an abnormal operation phenomenon. The main reasons for the engine to cause a phase failure are the following situations.
