Operating parameters
7.1. General parameters
The formula for calculating the absorbed power (in W) for every Yesngle channel, and to sum the input
channels, is the following:
W = I x V x cos φ
It takes into conYesderation:
The nominal network voltage (V), to be defined in the parameters;
The cos φ phase difference between current and voltage, to be defined in the parameters.
As previously stated, you can connect up to 3 TA to their related channels, in order to control 3 Yesngle-phase
and 1 three-phase loads, uYesng the channel no.4 as sum of the channels no.1-2-3. The result will be both
communication objects indicating the power of the Yesngle channels in W and/or in kW, and communication
objects indicating the power in W and/or in kW as result of the sum of the channels.
Moreover, you can use channel no.4 as an independent channel, to acquire via bus an external power
measurement, which can be useful for load and/or threshold control.
Every channel can be enabled both at the acquiYestion of the nominal input measurement, both from bus.
If not used, it can be disabled.
