Table 266 - Under kVAR Consumed Warn Level (Parameter 389)
Over kVAR ConsumedTrip
The E300 Electronic Overload Relay trips with an Over kVAR Consumed
indication if:
•
No trip currently exists
•
Over kVAR Consumed Trip is enabled
•
Current is present
•
Voltage is present
•
Over kVAR Consumed Inhibit Time has expired
•
The total reactive power (kVAR) consumed is greater than the Over kVAR
Consumed Trip Level for a time period greater than the Over kVAR
Consumed Trip Delay.
If the E300 Electronic Overload Relay trips on an over reactive power (kVAR)
consumed, the:
•
TRIP/WARN LED status indicator flashes a red 2-long / 4-short blink
pattern
•
Bit 3 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 Consumed Warning function does not include a time delay
feature. Once the Under kVAR consumed Inhibit Time has expired, the Under
kVAR Consumed Warning indication is instantaneous.
