| Do you Know why pump motor burns? |
| |
OVER CURRENT
Over Load, Voltage Fluctuations, Mechanical & Electrical
Malfunction, Phase Failure
UNDER CURRENT
Dry Run, Reverse Rotation, Mechanical Failure & Phase Failure
(Single Phasing) |
| |
| What Can we Do? |
| |
Now we know that the motor does not fail because of voltage but it burns because of Current.
So by monitoring and controlling the current variations, keeping them in its higher and lower allowable values, we can safeguard our motor!!! |
