This section shows the settings related to the Breaker definition such as shown in the following table
Table 3.9: GENERAL OVERVIEW OF BREAKER MENU
3.1.8.4 PROTECTION ELEMENTS
This option shows all the protection-grouped elements available in the relay as shown in Table 3.10: or Table 3.11: (depend
on firmware version). Each of these groups includes the specific protection units of the same type. For example phase
currents group includes TOC, IOC, directional units, etc. There are three groups available, so there are three protection
units of each function that can work in grouped mode or ungrouped (altogether). Users should take into account that
position of different Enervista 650 PC Menus could vary depending on relay firmware version.

Breaker settings
Breaker settings, maintenance and switchgear selection of the device
configured as breaker in the F650. The selected switchgear will be used
in recloser, breaker failure and synchronism functions. The settings are
Number of Switchgear, Maximum KI2t, KI2t Integ. Time, Maximum
Openings, Max.Openings 1 hour and Snapshot Events.
Breaker maintenance
These settings correspond to the initialization of (KI)
2
t counters, and the
counting of number of openings and closings of the switchgear
configured as breaker. These Counters allow the breaker Maintenance.
They are used to cumulate the breaker ageing produced by a trip or a
breaker opening. In order to incorporate the breaker historic, in case of
existing breakers, the system allows assigning an initial value to
accumulated amperes, and to the number of opening and closing
operations.
