Options enabled only in On-line mode are marked as (*). Options enabled only in Off-line mode are marked as (**)
4.1.8.2 SYSTEM SETUP
This section shows the settings related to the system setup definition such as shown in the following table.
Table 4–8: GENERAL OVERVIEW OF SYSTEM SETUP MENU:
Options enabled only in On-line mode are marked as (*). Options enabled only in Off-line mode are marked as (**)
4.1.8.3 PROTECTION ELEMENTS
This option shows all the protection-grouped elements available in the relay as shown in Table 4–9:. 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).
Serial Ports Baud rate and parity for COM1 and COM2 serial communication ports.
Network (Ethernet)
Ethernet communication parameters for COM3 (IP Address, Netmask,
Gateway IP)
NOTE: The ModBus Slave address used by Ethernet ports is the one set
for COM2.EnerVista 650 Setup software allows programming two
different Ethernet addresses, but the first IP has always to be set as the
second IP Address is an Alias.
ModBus Protocol
ModBus Slave Addresses for serial and Ethernet communication and the
ModBus port number used for ModBus TCP/IP
DNP3 Slave
Physical port, Slave Address for DNP, IP Addresses for Masters, TCP/
UDP Port, Unsolicited Response parameters, Analog scale factors and
deadbands, message fragment size, Binary input block.Available for
standard and IEC61850 models.
IEC 870-5-104
TCP Port, Common Addr of ASDU, Cyclic Meter Period and,
Synchronization Event settings.Available for standard and IEC61850
models.

SYSTEM
SETUP
General Settings
This screen describes and enables the settings of the power system
where the relay will operate. Some of these settings will be 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 so that
they fit the system settings.
Flex Curves
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 settings
Breaker settings, maintenance and switchgear selection of the device
configured as breaker in the G650. The selected switchgear will be used
in recloser, breaker failure and synchronism functions. The settings are
Number of Switchgear, Maximum KI
2
t, KI
2
t 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.
Switchgear Configuration of snapshot events for each switchgear (enable or disable)
