Thanks waross. You are correct. Just to note: pumps are associated with VFD motors. Best, Filip

At one of the pumping stations PQM shows when there is no pump running: Vab = 614 V Vbc = 617 V Vca = 614 V Ia = 6 A Ib = 7 A Ic = 7 A P = 2 kW A = 8 kVA PF = 0.27 When one pump is running the PQM shows: Vab = 618 V Vbc = 616 V Vca = 612 V Ia = 35 A Ib = 35 A Ic = 34 A P = 27 kW A = 37 kVA PF...

Hi, I am looking for the Power Quality Meter with capability to calculate parameters either 3 phase, single phase, 2 phase out of 3 or single phase system with 2 hot lines and neutral grounded middle point is used. The meter should have Modbus RTU/Modbus TCP communication to be used with GE...

The application is related to the collection system and pumps are pumping out to the same discharge point.

I have two VFD pumps emptying wet well. It is defined Duty 1 and Duty 2 Start and Stop setpoint and pumps minimum and maximum speed. If we have just one (Duty 1) pump running speed is easily defined by the slope (MaxSpeed-MinSpeed)/(Duty1StartLevel-Duty1StopLevel). In case when the level is...
