Over Power Factor Leading Trip
The E300 relay trips with an Over Power Factor Leading indication if:
• No trip currently exists
• Over Power Factor Leading Trip is enabled
• Current is present
• Voltage is present
• Over Power Factor Leading Inhibit Time has expired
• The total power factor leading is greater than the Over Power Factor
