14.6 Delta supervision of real input DELSPVC
14.6.1 Identification
Function description
Delta supervision of real input
14.6.2 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
The change over time of these quantities with respect to the old value can be supervised with
this function.
14.6.3 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.
DelSt> : This setting is used to set the start value for delta detection.
DeltaT : This setting defines the number of execution cycles of old data to be used for delta
calculation. That is, if
used to compare the change against.
tHold : This setting defines the pulse length for the start signal. A typical value of this setting is
100 ms.
