Protective Trip and Warning Functions
Under kVAR Generated Inhibit Time
Under kVAR Generated Inhibit Time (Parameter 394) allows you to inhibit an
under power factor leading trip and warning from occurring during the motor
starting sequence. It is adjustable from 0…250 seconds.
Table 262 - Under kVAR Generated Inhibit Time (Parameter 394)
Over kVAR Generated Inhibit Time
Over kVAR Generated Inhibit Time (Parameter 398) allows you to inhibit an
over reactive power (kVAR) generated trip and warning from occurring during
the motor starting sequence. It is adjustable from 0…250 seconds.
Table 263 - Over kVAR Generated Inhibit Time (Parameter 398)
Under kVAR Consumed Trip
The E300 Electronic Overload Relay trips with an Under kVAR Consumed
indication if:
•
No trip currently exists
•
Under kVAR Consumed Trip is enabled
•
Current is present
•
Voltage is present
•
Under kVAR Consumed Inhibit Time has expired
•
The total reactive power (kVAR) consumed is less than the Under kVAR
Consumed Trip Level for a time period greater than the Under kVAR
Consumed Trip Delay.
If the E300 Electronic Overload Relay trips on an under reactive power (kVAR)
consumed, the:
