6.12. Measure layout setting
Function
The PQRM5100 11 Ux Ix xx xx device can operate several
types of measurement setup. Here you can set the
measuring arrangement.
Possible measuring modes:
3 phase, 4 wire, 3 meter:
Three phase measurement with neutral conductor
3 phase, 3 wire, 3 meter:
Three phase measurement without neutral conductor
3 phase, 3 wire, 2 measure:
Three phase measurement without neutral conductor. Using
2 meter configuration. (Aron mode)
3 phase, 4 wire, 1 meter:
Three phase measurement with neutral conductor. Using 1
meter configuration. It is assumed symmetric load system,
so you can use the measurement of rotating electrical
machines.
3 phase, 3 wire, 1 meter:
Three phase measurement without neutral conductor. Using
1 meter configuration. It is assumed symmetric load system,
so you can use the measurement of rotating electrical
machines.
3 phase, 3 wire, 3 meter, 3fmv:
Three phase measurement without neutral conductor, and
three phase voltage transformers with delta secondary
winding. The secondary winding of the transformer is
connecting to earth. The Voltage transformers ratio is
multiplied
√ 3!
