Observing Surges in the Field

Practical notes on surge counters, failure indicators, and logging.

Many SPDs show green/red mechanical flags when a cartridge reaches end of life. Train maintenance teams to check them during rounds.

A floating changeover contact can feed BMS/SCADA so a failed SPD is replaced before the next storm season.

Counters help justify protection upgrades by showing how often the site is stressed—especially useful for coastal and tropical facilities.
