DESCRIPTION
IREF> Is 3A 65 0.2
From 0.05*I3 to 1.0*I3 in steps of 0.01*I3
[Courier Number (current)]
Pick-up setting for the High Impedance restricted earth fault element.
VN Input 3B 01 Derived
Measured
Derived
[Indexed String]
Data cell indicating the VN Input is always derived from the 3 phase voltages
VN>1 Function 3B 02 DT
Disabled
DT
IDMT
[Indexed String]
Setting for the tripping characteristic of the first stage residual overvoltage element.
VN>1 Voltage Set 3B 03 5
From 1*V1 to 50*V1 in steps of 1*V1
[Courier Number (voltage)]
Pick-up setting for the first stage residual overvoltage characteristic.
VN>1 Time Delay 3B 04 5
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Operating time delay setting for the first stage definite time residual overvoltage element.
VN>1 TMS 3B 05 1
From 0.5 to 100 in steps of 0.5
[Courier Number (Decimal)]
Setting for the time multiplier setting to adjust the operating time of the IDMT characteristic.
The characteristic is defined as follows:
t = K / ( M – 1)
Where:
K = Time multiplier setting
t = Operating time in seconds
M = Derived residual voltage/relay setting voltage (VN> Voltage Set)
VN>1 tReset 3B 06 0
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Setting to determine the reset/release definite time for the first stage characteristic
VN>2 Status 3B 07 Disabled
Disabled
Enabled
[Indexed String]
Setting to enable or disable the second stage definite time residual overvoltage element.
VN>2 Voltage Set 3B 08 10
From 1*V1 to 50*V1 in steps of 1*V1
[Courier Number (voltage)]
Pick-up setting for the second stage residual overvoltage element.
VN>2 Time Delay 3B 09 10
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Operating time delay for the second stage residual overvoltage element.
GROUP 1: THERMAL
OVERLOAD
3C 00
This column contains settings for Thermal Overload
Characteristic 3C 01 Single
Disabled

Thermal Alarm 3C 03 70
From 50 to 100 in steps of 1
[Courier Number (percentage)]
Setting for the thermal state threshold corresponding to a percentage of the trip threshold at which an alarm will be generated.
