In general, a surge is a transient wave of current, voltage, or power in an electric circuit. In power systems in particular – and this is likely the most common context that we relate surges to – a surge, or transient, is a sub-cycle over voltage with a duration of less than a half-cycle of the normal voltage waveform. A surge can be either positive or negative polarity, can be additive or subtractive from the normal voltage waveform, and is often oscillatory and decaying over time.
Surges, or transients, are brief over voltage spikes or disturbances on a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, industrial, or manufacturing facility. Transients can reach amplitudes of tens of thousands of volts. Surges are generally measured in microseconds. For more visit www.arcimpulseinc.com
