Single Phasing Motor Problem: Causes, Analysis and Prevention

1 day ago · During phase failure the current in the other two phases theoretically increases by 173% or by a factor of 1.73 of the normal running current which can go all the way up to 200% because of the power factor changes. This results in current being drawn above the safe limit which can heat the coils inside the motor leading to motor failure.

Horsepower = 275, Voltage = 460. Chart value of 1.2A/HP multiplied by 275 HP = 330A. 330A X 1.25 = 412.5A. Closest standard current transformer ratio is 400/5. For single-phase motors, determine full load current from the nameplate rating. Multiply by 1.25 to get the approximate CT rating, as shown above. Next Steps:
