Table 274 - Over kVAR Generated Trip Level (Parameter 400)
Over kVAR Generated Warning
The E300 Electronic Overload Relay indicates an Over kVAR warning if:
•
No warning currently exists
•
Over kVAR Generated Warning is enabled
•
Current is present
•
Voltage is present
•
Over kVAR Generated Inhibit Time has expired
•
The total reactive power (kVAR) generated is equal to or greater than the
Over kVAR Generated Warning Level
When the Over kVAR Generated Warning conditions are satisfied, the:
•
TRIP/WARN LED flashes a yellow 2-long / 6-short blink pattern
•
Bit 5 in Power Warning Status (Parameter 12) sets to 1
•
Bit 1 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Warning Alarm close
Over kVAR Generated Warn Level
Over kVAR Generated Warn Level (Parameter 401) allows you to define the
reactive power (kVAR) generated at which the E300 Electronic Overload Relay
indicates a warning. It is user-adjustable from 0…2,000,000 kW.

IMPORTANT
The Over kVAR Generated Inhibit Time starts after a phase voltage transitions
from 0V to 20V L-L and a phase of load current transitions from 0 A to 30% of
the minimum FLA setting of the device. The E300 Electronic Overload Relay
does not begin monitoring for an over reactive power (kVAR) generated
condition until the Over kVAR Generated Inhibit Time expires.
