At the starting of the over/under voltage events (event code 76, 77, 78, 79, 80, 81) the
following parameters are stored in the Power Quality log too
• Starting time of the Over/Under voltage
• Number of the Over/Under voltage
At the end of the over/under voltage events (event code 217, 218, 219, 220, 221, 222) the
following parameters are stored in the Power Quality log too
• End time of the Over/Under voltage
• Duration of last Over/Under voltage
• Magnitude of the last Over/Under voltage
