Explanation

Impulsive transients are sudden, brief spikes in voltage or current that rise and fall rapidly, often caused by lightning strikes, switching operations, or electrostatic discharge. IGBTs (Insulated Gate Bipolar Transistors) are semiconductor switching devices used in power electronics, not a power quality disturbance. Interruptions refer to a complete or near-complete loss of voltage or current for a period of time, which is the opposite of a spike. Power factor is a measure of how efficiently electrical power is consumed, describing the ratio of real to apparent power, not a type of disturbance.

Memory tip: Think of "impulsive" as something that acts on impulse -- sudden and forceful, like a lightning bolt hitting a power line and causing an instantaneous voltage surge.
