7.4.1

Power Measurement on a Machine

For measuring power, all of the eight CAGE CLAMPS

have to be connected

according to the figure below.

Do not confuse current and voltage clamps!

When making the connections do not confuse the current and voltage paths, as

connecting the phase voltages directly to the low impedance current clamps IL1

… IL3 shall destroy the I/O module!

Figure 17: Power Measurement on a Machine

Negative power values!

If you measure negative power values, check the connection of the associated

current transformer circuit in the proper direction.

7.4.2

Power Measurement on Two Motors Regulated by

Frequency Converters

The example here illustrates power measurement on two 3-phase motors regulated

by a frequency converter (ac power converter) used e. g. in a conveyor system.

Each of these motors is monitored by a 3-phase power measurement module.
