Over kVAR Generated Trip
The E300 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
