Description
The overvoltage trip level is entered here as a percentage of the VT rating.
The range of possible settings for the overvoltage trip setpoint is 101% to
120 %VT
125% of the VT rating in steps of 1%. The breaker must be closed for
overvoltage trips to be detected. Refer to Table 2.1 to determine how many
phases must be above the trip level to cause a trip for the VT connection
being used.
The delay on the overvoltage trip is entered here, in the range of 0.1 to
25.5 seconds in steps of 0.1 seconds. This delay prevents nuisance trips.
1.0 SEC
Should the condition persist beyond the timed period the trip will occur.
This message allows the user to select the relay which the trip signal
generated in message S 9.14, will activate.
TRIP
This message allows the overvoltage alarm to be enabled or disabled.
DISABLED
The overvoltage alarm level is entered here as a percentage of the VT
rating. The 565 Relay monitors the phase voltages and provides an alarm
115 %VT
if the level rises to the level which you enter here. The range of possible
settings for the overvoltage alarm setpoint is 101% to 125% of the VT
rating in steps of 1%. Refer to Table 2.1 to determine how many phases
must be above the alarm level to cause an alarm for the VT connection
being used.
The delay on the overvoltage alarm is entered here, in the range of 0.1 to
25.5 seconds in steps of 0.1 seconds. As for the undervoltage delay, this
1.0 SEC
delay prevents nuisance trips due to momentary high signals. Should the
overvoltage persist beyond the timed period the alarm will occur.
This message allows the user to select the relay which the alarm signal
generated in message S 9.18 will activate.
