Protective Trip and Warning Functions
Chapter 6
Under Power Factor Leading Trip
The E300 Electronic Overload Relay trips with an Under Power Factor Leading
indication if:
•
No trip currently exists
•
Under Power Factor Leading Trip is enabled
•
Current is present
•
Voltage is present
•
Under Power Factor Leading Inhibit Time has expired
•
The total power factor leading is less than the Under Power Factor Leading
Trip Level for a time period greater than the Under Power Factor Leading
Trip Delay.
If the E300 Electronic Overload Relay trips on an under power factor leading,
the:
•
TRIP/WARN LED status indicator flashes a red 2-long / 11-short blink
pattern
•
Bit 10 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 Over Power Factor Lagging Warning function does not include a time delay
feature. Once the Over Power Factor Lagging Inhibit Time has expired, the Over
Power Factor Lagging Warning indication is instantaneous.
