Blocking of signals during test (BST)
7.1
Application
The protection and control terminals have a complex configuration with many included func-
tions. To make the testing procedure easier, the terminals include the feature to individually
block a single, several or all functions.
This means that it is possible to see when a function is activated or trips. It also enables the user
to follow the operation of several related functions to check correct functionality and to check
parts of the configuration etc.
