Chapter 6 Protective Trip and Warning Functions
Under kVAR Generated Trip
The E300 Electronic Overload Relay trips with an Under kVAR Generated
indication if:
• No trip currently exists
• Under kVAR Generated Trip is enabled
• Current is present
• Voltage is present
• Under kVAR Generated Inhibit Time has expired
• The total reactive power (kVAR) generated is less than the Under
• kVAR Generated Trip Level for a time period greater than the Under
kVAR Generated Trip Delay.
If the E300 Electronic Overload Relay trips on an under reactive power (kVAR)
generated, the:
• TRIP/WARN LED status indicator flashes a red 2-long / 5-short blink
pattern
• Bit 4 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)
The Over kVAR Consumed Warning function does not include a time delay
feature. Once the Over kVAR Consumed Inhibit Time has expired, the Over kVAR
Consumed Warning indication is instantaneous.
