*7.2. Capacitive Switching*

An event of capacitor switching is realized at node 675 by switching off the connected capacitor banks at 4th cycle and again switching on at 8th cycle. Voltage and current signals recorded on node 650 are processed to obtain the FI using WD-index and ALN-index as illustrated in Figure 15. It is inferred from Figure 15 that FI has lower values compared to the threshold during the event of switching off and on of the capacitor bank. Hence, it is established that algorithm is effective for the discrimination of the capacitor switching event from the faulty events.
