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...
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...
