Reclosers are electrical utility devices used to isolate faults occurring in an electrical grid. In their operation, if a fault is detected, they may disconnect and reconnect power several times. From the utility customer’s point of view they may experience voltage sags and swells during this time. These sags and swells can be easily viewed when these events are plotted on an ITIC curve, also known as a CBEMA curve. The ITIC curve simplifies these events into single points representing duration and magnitude. This whitepaper will explore why these recloser operations produce events that violate the ITIC curve.
