3.1.7.4 Breaker menu

Breaker settings Breaker settings, maintenance and switchgear selection of the device configured as breaker in the F650. The
selected switchgear is 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)
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.

3.1.7.5 Protection elements menu

This option shows all protection elements available in the relay as shown in the following two tables (exact menu depends
on firmware version).
For firmware versions below 7.50, each group of protection elements 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).

This screen describes and enables the settings of the power system where the relay
operates. Some of these settings are used only for metering values presentation purposes;
however, some of them apply directly to the sampling and analog-digital conversion
process (rated frequency setting). Therefore, these settings need to be adjusted to fit the
system settings.
Flex Curves – Programmable user curves: The relay incorporates 4 user curves called Flex
Curve A, B, C and D. The points for these curves are defined by the user in Setpoint >
System Setup > Flex Curves > Edit Curve menu in EnerVista 650 Setup. User defined flex
curves can be selected as an operation curve in all the time overcurrent functions in the
relay.
Breaker Configuration
Configuration of snapshot events for each switchgear (enable or disable)
This screen contains settings related with relay working mode. Out of service setting,
Local/Remote mode and Active language mode are options listed below.
All overcurrent functions for phase current.
All overcurrent functions for neutral current. (Calculated from phases, not measured)
All overcurrent functions for ground current. (Measured from 4th current input)
All overcurrent functions for sensitive ground current. (Measured from 5th current input)
All Negative sequence overcurrent functions.
All voltage functions for phases, neutral, ground and auxiliary voltage
Forward power, directional power and wattmetric ground fault (High and Low) protection
functions.
