5.2.3 FAULT REPORT
5.2.3.1 OVERVIEW
The fault report module defines the type of fault (three-phase, phase-to-phase, phase-to-ground), and the distance to the
fault. The fault activation signal (FAULT REPORT TRIGG) is programmed at “
Setpoint > Relay Configuration >
Protection Elements
”.
The fault report provides fault date, fault type and fault location information.
Information referred to the last ten faults is stored as fault report and available to the user through the EnerVista 650 Setup
software or the web server application. Each fault report includes the following information:
• Fault date and time
• Pre-fault current and voltage in primary values
• Fault current and voltages in primary values
• Fault type
• Distance to the fault (fault location)
• Line parameters
• Recloser and breaker status information
As an option, the Relay offers the possibility to display a fault-warning message on the relay HMI (selectable by setting).
5.2.3.2 FAULT REPORT SETTINGS
Table 5–9: FAULT REPORT SETTINGS
Function permission (Function):
Enabling this setting allows to create a fault report when the FAULT REPORT TRIGG is
activated.
Positive sequence impedance module (Pos Seq Module):
Value, in ohms, of the line positive sequence
impedance module.
Positive sequence impedance Angle (Pos Seq Angle):
Value, in degrees, of the line positive sequence angle.
Zero sequence impedance module (Zero Seq Module):
Value, in ohms, of the line zero sequence impedance
module.
Zero sequence impedance Angle (Zero Seq Angle):
Value, in degrees, of the line zero sequence angle.
Line Length:
The metering element can be kilometers or miles.
Show Fault On HMI:
This setting enables or disables the option to display
faults on the Relay HMI.
Snapshot Events:
This setting enables or disables the snapshot event
generation for the fault report element.
