Detailed explanation-1: -A voltage spike is a sudden increase in voltage that lasts for less than three nanoseconds. A sudden increase in voltage that lasts for three nanoseconds or more is called a voltage surge. They are harmful because they cause the wires in your electronic equipment to overheat.

Detailed explanation-2: -What Is a Power Surge? Power surges are just as the name suggests: surges of electrical power that are higher than normal. Typical voltage levels for household appliances and electronics are between 110 volts and 220 volts in most countries, with the United States operating on 120 volts on average.

Detailed explanation-3: -Voltage Surge The main cause of these voltage surges in power system are due to lightning impulses and switching impulses of the system. But over voltage in the power system may also be caused by, insulation failure, arcing ground and resonance etc.

Detailed explanation-4: -But when a power surge occurs, it causes a flow of electricity that spikes above 169 volts, resulting in an arc of electrical current. This arc generates heat that is damaging to electronic components and circuit boards.

Detailed explanation-5: -Electric Power Transmission In general, switching surges occur in the vicinity of non-self-restoring insulation equipment such as generators, transformers, breakers, and cables. Overvoltages caused by switching surges are a concern since they can damage insulation or cause insulation flashover.
