When inverse time overcurrent characteristic is selected, the operate 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.
The parameters for the four step residual overcurrent 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 (
IBase ), primary voltage ( UBase ) and primary
power (
SBase ) are set in global base values for settings function GBASVAL.
GlobalBaseSel : Selects the global base value group used by the function to define IBase , UBase
and SBase . Note that this function will only use IBase value.
SeqTypeUPol : This is used to select the type of voltage polarising quantity i.e. Zero seq or Neg
seq for direction detection.
SeqTypeIPol : This is used to select the type of current polarising quantity i.e. Zero seq or Neg
seq for direction detection.
SeqTypeIDir : This is used to select the type of operating current quantity i.e. Zero seq or Neg
seq for direction detection.

AngleRCA : Relay characteristic angle given in degree. This angle is defined as shown in
Figure 94. The angle is defined positive when the residual current lags the reference voltage
