Electric Wiring Diagram
F-PM-100 series meter supports multiple measuring wiring mode, and is described respectively by graphic method as below.
When measuring voltage is less than 300V (phase) / 520V (line), three-phase four-wire system no need to use PT but direct measurement.
When measuring zero sequence current, the using secondary circuit current of zero sequence current transformer is 0.02-1A.
