Figure 3: Menu structure
All of the settings in the menu fall into one of three categories: protection settings,
disturbance recorder settings, or control and support (C&S) settings. One of two
different methods is used to change a setting depending on which category the
setting falls into. Control and support settings are stored and used by the relay
immediately after they are entered. For either protection settings or disturbance
recorder settings, the relay stores the new setting values in a temporary ‘scratchpad’.
It activates all the new settings together, but only after it has been confirmed that the
new settings are to be adopted. This technique is employed to provide extra security,
and so that several setting changes that are made within a group of protection
settings will all take effect at the same time.
3.3.1 Protection settings
The protection settings include the following items:
−
protection element settings
− scheme logic settings
− auto-reclose and check synchronisation settings (where appropriate)*
− fault locator settings (where appropriate)*
There are four groups of protection settings, with each group containing the same
setting cells. One group of protection settings is selected as the active group, and is
used by the protection elements.
3.3.2 Disturbance recorder settings
The disturbance recorder settings include the record duration and trigger position,
selection of analogue and digital signals to record, and the signal sources that trigger
the recording.
