What is the purpose of an SPD?
While lightning strikes often dominate the headlines regarding electrical failures, they account for a minority of actual equipment damage. Industry data suggests that nearly 65% to 80% of all transient overvoltage events originate internally within a facility. Every time a heavy motor, HVAC compressor, or elevator switches on or off, it generates a micro-spike that degrades sensitive electronics. These silent killers accumulate over time, leading to what engineers call "electronic rust" and eventual premature failure.
