Section 11
Secondary system supervision
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 IBase to use this function as fault detection.
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
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
should be modified. Typical setting is 15% of fundamental signal.
StValGrad: This setting is used to modify the DelI> based on 3
modify the DelI>.
11.5 Delta supervision of real input DELSPVC
11.5.1 Identification
Function description
Delta supervision of real input
11.5.2 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
The change over time of these quantities with respect to the old value can be supervised with this
function.
11.5.3 Setting guidelines
Operation: This setting is used to enable/disable the delta supervision function.
MinStVal: The minimum start level of the function. If the input is below this level, the function will be
blocked. It should be set depending on the input connected.
