Protective Trip and Warning Functions Chapter 5
Under kVAR Generated Trip
The E300 Electronic Overload Relay will trip with an Under kVAR Generated
indication if:
No trip currently exists
Under kVAR Generated Trip is enabled
Current is present
Voltage is present
Under kVAR Generated Inhibit Time has expired
The total reactive power (kVAR) gen
e
rated is less than the Under
kVAR Generated Trip Level for a time period greater than the Under
kV
AR Generated Trip Delay.
If the E300 Electronic Overload Relay trips on an under reactive power (kVAR)
gene
rated, the:
T
RIP/WARN LED status indicator will flash a red 2-long / 5-short blink
pa
ttern
Bit 4 in Power Trip Status (Parameter 6) will set to 1
Bit 0 in Device Status 0 (Parameter 20) will set to 1
Any relay outputs configured as a Trip Relay will open
Any relay outputs configured as a Control Relay will open
Any relay outputs configured as a Trip Alarm will close
Any relay outputs configured as a Normal Relay will be placed in their
P
r
otection Fault state (if so programmed)
IMPORTANT
The Over kVAR Consumed Warning function does not include a time delay
feature. Once the Over kVAR Consumed Inhibit Time has expired, the Over kVAR
Consumed Warning indication is instantaneous.
