Got a motor driven pump. 75 HP, 3 phase, 460 V, SF 1.15. Nameplate FLA is 87A. The pump is on a constant flow system.
Amprobed it at 96, 100, 104 amps. Voltages are within 2 volts of each other.
Is this something I should be worried about? 87 X 1.15 is 100. I am not concered with the imbalance as much as the fact that the motor is running at max all the time.
I know next to nothing about pumps so is this something I should worry about? This motor/pump combo is a backup to another pump that just failed. It has not run in about 2 years .
Many thanks
