Protective Trip and Warning Functions Chapter 6
Table 272 - Under kVAR Generated Warn Level (Parameter 397)
Over kVAR Generated Trip
The E300 Electronic Overload Relay trips with an Over kVAR Generated
indication if:
• No trip currently exists
• Over kVAR Generated Trip is enabled
• Current is present
• Voltage is present
• Over kVAR Generated Inhibit Time has expired
• The total reactive power (kVAR) generated is greater than the Over
• kVAR Generated Trip Level for a time period greater than the Over kVAR
Generated Trip Delay.
If the E300 Electronic Overload Relay trips on an over reactive power (kVAR)
generated, the:
• TRIP/WARN LED status indicator flashes a red 2-long / 6-short blink
pattern
• Bit 5 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 Generated Warning function does not include a time delay
feature. Once the Under kVAR generated Inhibit Time has expired, the Under
kVAR Generated Warning indication is instantaneous.
