8.2.2 Identification
Function description
Directional residual overcurrent
protection, four steps
8.2.3 Setting guidelines
The parameters for the four step residual over-current protection are set via the local HMI or
PCM600. The following settings can be done for the function.
Common base IED values for the primary current (
SBase ) are set in global base values for settings function GBASVAL.
power (
GlobalBaseSel : Selects the global base value group used by the function to define IBase , VBase and
SBase . Note that this function will only use IBase value.
SeqTypeUPol : This is used to select the type of voltage polarising quantity (that is, Zero seq or
Neg seq for direction detection).
SeqTypeIPol : This is used to select the type of current polarising quantity (that is, Zero seq or Neg
seq for direction detection).

2.2.4 The phase selection logic is added to allow phase segregated trip. The new phase
selections outputs added to this release are PHSELL1, PHSELL2 and PHSELL3. The
setting EnPhaseSel is added to enable or disable phase selection. The maximum value
changed to 2000.0 % of IBase for

When inverse time over-current characteristic is selected, the trip time of the stage
will be the sum of the inverse time delay and the set definite time delay. Thus, if
only the inverse time delay is required, it is important to set the definite time delay
for that stage to zero.
