What are the limitations of the power applied to my pump station ?
A. Generally the voltage applied should be + 10% of the specific design voltage. The frequency should be + 1Hz of the specific design frequency.The larger the motor the more important it is to maintain a tighter voltage and frequency tolerance especially under full load conditions with all pumps running. Remember that “soft” power can be damaging “Soft” power is such that under higher current demands, the voltage drops precipitatously low causing high current and possible damaging heat in the motor.
