Unbalanced 3-Phase Stator Current Cause at Shaunta Moorer blog

Unbalanced 3-Phase Stator Current Cause. Current unbalance can be caused either by a voltage unbalance or by a problem with the wiring to the motor, a fault in the motor, or the. Remember, our earth fault relays are set at 20% of full rated load current to avoid tripping due to unbalance load current. All motors need protection against overheating resulting from overload, stalled rotor, or unbalanced stator currents. In an unbalanced 3 phase system, positive, negative & zero sequence impedance exists. Unbalanced voltages at motor terminals can cause a phase current imbalance of up to 10 times the percentage voltage imbalance for a fully loaded motor. Unequal voltages usually are caused by unbalanced loads on the power source, a poor connection at the motor terminal, or a high resistance contact (weak. In three phase systems, current unbalance is defined as the maximum deviation of any phase current from average divided by average current.
