Table 272 - Under kVAR Generated Warn Level (Parameter 397)
Over kVAR Generated Trip
The E300 Electronic Overload Relay trips with an Over kVAR Generated
indication if:
•
No trip currently exists
•
Over kVAR Generated Trip is enabled
•
Current is present
•
Voltage is present
•
Over kVAR Generated Inhibit Time has expired
•
The total reactive power (kVAR) generated is greater than the Over
•
kVAR Generated Trip Level for a time period greater than the Over kVAR
Generated Trip Delay.
If the E300 Electronic Overload Relay trips on an over reactive power (kVAR)
generated, the:
•
TRIP/WARN LED status indicator flashes a red 2-long / 6-short blink
pattern
•
Bit 5 in Power Trip Status (Parameter 6) sets to 1
•
Bit 0 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Trip Relay open
•
Any relay outputs configured as a Control Relay open
•
Any relay outputs configured as a Trip Alarm close
•
Any relay outputs configured as a Normal Relay are placed in their
Protection Fault state (if so programmed)

IMPORTANT
The Under kVAR Generated Warning function does not include a time delay
feature. Once the Under kVAR generated Inhibit Time has expired, the Under
kVAR Generated Warning indication is instantaneous.
