7.3.1 Measure input settings

In the 7.1 Measure configurations menu you can set the how

connect the device to network. Here you can set the voltage

and currents transformers for inputs (if they are usable) and

other special parameters of the measurement.

The device can operate several types of measurement

setup. In the 7.1 Measure configurations menus 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

threephase voltage transformers with delta secondary

winding. The secondary winding of the transformer is

connecting to earth. The Voltage transformers ratio is

multiplied √3!

You can find the electrical wiring diagrams for each

measurement arrangement on 5. Connecting chapter.
