Menu structure

The relay's menu is arranged in a tabular structure. Each setting in the menu is referred to
as a cell, and each cell in the menu may be accessed by reference to a row and column
address. The settings are arranged so that each column contains related settings, for
example all of the disturbance recorder settings are contained within the same column. As
shown in Figure 3, the top row of each column contains the heading which describes the
settings contained within that column. Movement between the columns of the menu is only
possible at the column heading level. A complete list of all of the menu settings is given in
the manual.
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.
