Section 13
Secondary system supervision
Imin : The minimum pickup level setting should be set as % of IBase . This setting enables the
function to start detecting delta. Typical setting is 10% of
MeasMode : This setting is used to detect the mode of measurement; phase to phase or phase to
ground .
OpMode : This setting is used to select the mode of operation. For protection applications, this
should be set to
DelI> : This setting is used to detect the pickup value for instantaneous sample, RMS, DFT mag
based delta detection. Set a typical value of 200% of
DeltaT : This setting defines the number of old cycles data to be used for delta calculation in
RMS/DFT Mag mode. Typical value is 2 cycles.
tHold : This setting defines the pulse length for supervision pickup signal. Typical value is 100 ms.
EnaHarm2Blk : This setting should be set to ON, to enable blocking for heavy inrush currents or
other sources of 2
Harm2BlkLev : This is the blocking level of 2
Typical setting is 15% of fundamental signal.
EnStValAdap : This setting should be set to ENABLE in special networks where settings in the
network are adapted with respect to 3
Harm3Level : This is the set level of 3
DelI> should be modified. Typical setting is 15% of fundamental signal.
StValGrad : This setting is used to modify the DelI> based on 3

13.6 Delta supervision of real input DELSPVC
13.6.1 Identification
Function description
Delta supervision of real input
13.6.2 Application
Delta supervision of real input DELSPVC is a general processed input delta supervision. It is used
to configure any processed inputs such as:
• Power (S)
• Active power (P)
• Reactive power (P)
• Thermal heat content (ɸ)
• Energy
