6.3.4 Analog channel configuration
HZCCxSPVC has one analog group input which must be properly configured.
Table 1253: Analog inputs
Input Description
I3P Three-phase currents
See the preprocessing function blocks in this document for the possible
signal sources.
Improper analog channel configuration causes a validation error if the analog
channels are not completely configured or they do not match with certain settings.
For troubleshooting, check the contents of this chapter and also the preprocessing
blocks in this document. The configuration can be written to the protection relay
once the mismatch is corrected.
6.3.5 Operation principle
The function can be enabled and disabled with the
Operation
setting. The
corresponding parameter values are "On" and "Off".
The operation of HZCCxSPVC can be described with a module diagram. All the
modules in the diagram are explained in the next sections.
The module diagram illustrates all the phases of the function. However, the
functionality is described only for phase A. The functionality for phase B and C is
identical.
