GoEna 00000000 00000000 11111111 1
GoEna (GOose ENAble) is a setting to enable GOOSE (Generic Object Orientated
Substation Event, for high-speed inter-device messaging) publisher settings. This setting
enables (“1”) or disables (“0”) GOOSE control blocks from 08 (first digit) to 01 (last digit).
Test Mode 00000000 00000000 11111111 1
The Test Mode cell allows the test pattern to be sent in the GOOSE message, for example
for testing or commissioning.
The setting enables (“1”) or disables (“0”) test mode for GOOSE control block from 08 (first
digit) to 01 (last digit).
Once testing is complete the cell must be set back to ‘Disabled’ to restore the GOOSE
scheme back to normal service.
Ignore Test Flag No No, Yes
When set to ‘Yes’, the test flag in the subscribed GOOSE message is ignored, and the
data treated as normal.
3.15 Supervision (“Supervision” menu)
The “Supervision” menu contains 3 sections:
• the Voltage Transformer Supervision (VTS) section, for analog ac voltage inputs
failures supervision,
• the Current Transformer Supervision (CTS) section, for ac phase current inputs
failures supervision,
• the Capacitive Voltage Transformer Supervision (CVT) section, for voltage dividers
capacitors supervision.

SUPERVISION – GROUP 1
VT Supervision – Group 1
VTS Time Delay 5.00 s 1.00 s 20.00 s 1.00 s
The VTS function issues an alarm signal when the Voltage Transformer is lost, when the
VTS time-delay has elapsed. If an opto input is used to detect a VT failure, the blocking
protection is instantaneous.
VTS I2 & I0 Inh 50.00 mA 0.00 A 1.00 A 10 mA
Sets negative sequence current and zero sequence current thresholds. If negative
sequence and zero sequence currents exceed the threshold, the VTS alarm is inhibited
(see section “Supervision / Loss of one or two phases voltages” below – P44x/EN AP).
Detect 3P Disabled Enabled / Disabled
Disables or enables the loss of the three phase voltages.
Threshold 3P 30.00 V 10.00 V 70.00 V 1.00 V
Sets the phase voltage level.
Delta I> 100.0 mA
