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, which one of the nine available
measuring modes shall be used within the function. Available options are summarized in the
following table:
