www.bharathuniv.ac.in(metal-oxide varistors). An oscillatory transient is a brief, bidirectional variation in voltage, current, or both on a power line. These can occur due to the switching of power factor correction capacitors, or transformer ferroresonance. An interruption is defined as a reduction in line-voltage or current to less than 10 percent of the
