The relay supports sending of one and receiving of four IEC 61850-9-2 SV streams. In 9-2LE mode each stream contains four currents and four voltages. In IEC 61869-9 mode stream may contain 1-24 freely selectable channels. 24 received measurements in total can be connected into the protection relay application. 

Sampled measured value data sets must be defined according to IEC 61850-9-2 LE or IEC 61869-9.

  • Data set name must be PhsMeas1 or PhsMeas2.
  • SampledValueControl name must be MSVCB01, MSVCB02 or MSVCB03.
  • In IEC 61850-9-2 LE mode the contents of PhsMeas data set must not be modified. In IEC 61869-9 mode the PhsMeas dataset content must be defined by the engineer.
