Protective Trip and Warning Functions Chapter 6
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)
Default Value 0.000
Minimum Value 0.000
Maximum Value 2000000.000
Parameter Type DINT
Size (Bytes) 4
Scaling Factor 1000
Units kVAR
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.
