Default setting: 180 s 0 Forced search delay: s A shorter response time can set for changes that not have take the history the grid's state into account, for example, switching from manual automatic site or through the SCADA system.2) for longer than the set search delay. the zero sequence voltage returns the tolerance range before the end the delay, the counter reset its maximum predefined time. During the delay time, the time remaining until the search starts displayed the status bar. Evaluation the absolute value the zero sequence voltage search process started when the zero sequence voltage either outside the biggest circuit (1) inside the small- est circuit (2) during the total delay time after the grid switches. The circuit defined relative value the last saved zero sequence voltage.1.8) (Uref 1.Page 100 Detailed description REG-DP/ REG-DPA parameters We take care it. 1 The parameter 'Une angle measurement' must enabled and the Usync voltage (refer- ence voltage) must connected. Evaluation the absolute value and angle the zero sequence voltage search process is started when the zero sequence voltage outside the circuit (3) during the total delay time after the grid switches.3. 0 Delay search by: s The zero sequence voltage must outside the tolerance range during the delay order for search start. The factory setting reduce the waiting times during commissioning. 1 Evaluating the absolute value and angle reveals that considerably more grid switches were performed. 0 Une tolerance: A value 20% (default value) means that search process started when the zero se- quence voltage outside the set tolerance range (Uref 0.2 Tuning point 0 Target tuning type This parameter determines how tuning determined .
