MENU TEXT
IREF> Is
Pick-up setting for the High Impedance restricted earth fault element.
VN Input
Data cell indicating the VN Input is always derived from the 3 phase voltages
VN>1 Function
Setting for the tripping characteristic of the first stage residual overvoltage element.
VN>1 Voltage Set
Pick-up setting for the first stage residual overvoltage characteristic.
VN>1 Time Delay
Operating time delay setting for the first stage definite time residual overvoltage element.
VN>1 TMS
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
Setting to determine the reset/release definite time for the first stage characteristic
VN>2 Status
Setting to enable or disable the second stage definite time residual overvoltage element.
VN>2 Voltage Set
Pick-up setting for the second stage residual overvoltage element.
VN>2 Time Delay
Operating time delay for the second stage residual overvoltage element.
GROUP 1: THERMAL
OVERLOAD
This column contains settings for Thermal Overload
Characteristic
Setting for the operating characteristic of the thermal overload element.
Thermal Trip
Sets the maximum full load current allowed and the pick-up threshold of the thermal characteristic.
Thermal Alarm
Setting for the thermal state threshold corresponding to a percentage of the trip threshold at which an alarm will be generated.
Time Constant 1
Setting for the thermal time constant for a single time constant characteristic or the first time constant for the dual time constant
characteristic.
