    DETECTING TRANSIENTS
    An electrical transient is commonly defined as an instantaneous change in state leading to a burst of energy for a limited time. The causes can be either external or internal to a system. One primary cause of transient events is Lightning. Their mode of action is usually indirect and exerts it through affecting the power line. Other causes of transients include facility load switches, on/off disconnects (on energized lines), capacitor banks switching, and transformer tap changing.

    Transients can have significant adverse effects on the accuracy, efficiency, and remaining useful life of electronic equipment. The effects of transients on motors can be even more profound in the sense they can exhibit excessive heat build-up. Transients can also interfere with the timing of devices and can ultimately cause insulation to break down. Hysteresis losses are also increased and that can lead to more current drawn by the motor for the same output.
