Sources, hazards and protection measures of surges
What is a surge? Surges are called transient overcurrents, which are short-term current and voltage fluctuations in circuits, usually lasting about one millionth of a second in the circuit. A voltage fluctuation of 5,000 or 10,000 volts that lasts for a moment (one millionth of a second) in a 220-volt circuit system is a surge…
