Mode of operation
The measurement function must be connected to three-phase current and three-phase
voltage input in the configuration tool (group signals), but it is capable to measure and
calculate above mentioned quantities in nine different ways depending on the available
VT inputs connected to the IED. The end user can freely select by a parameter setting,
Y1...Y7 : Cyclic reported values, depending upon time Δt.
