5.3SYSTEM SETUP
This section shows the settings related to the system setup definition.
5.3.1 GENERAL SETTINGS
This section determines the settings of the element configuration regarding its connection to the power system.
Access to these settings using the EnerVista 650 Setup software is at
Setpoint > System Setup > General settings.
The corresponding settings are shown on the table below:
Table 5–21: GENERAL SETTINGS
The system rated voltage is used as reference by the voltage restraint in the phase timed overcurrent element.
The Frequency reference marks the voltage channel to which the system Frequency is measured.
The auxiliary voltage setting can be selected between VN and VX.
VN means that all elements using neutral voltage will take the value directly from the fourth voltage input.
VX means that all elements using neutral voltage will take the value calculated from phase voltages.
5.3.2 FLEX 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”
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.
In the flex curves menu there are 120 points to define a user curve. 40 points for reset (from 0 to 0.98 times the pickup
value) and 80 for operate (from 1.03 to 20 times the pickup).
