Monitor surge events through an impulse counter for discharges on surge protection devices.
A surge counter is an intelligent device that detects and records the quantity of voltage spikes during surge protection device operation. Surge counters that use inductive probes to estimate the number of surges are required for safety technology. If a surge occurs on the electrical system at or above 150V line-to-ground or line-to-neutral, a surge counter will count it. Every timeline noise emitted from a 120V sine wave exceeds the line noise threshold, a surge counter will increase. The noise is most likely a result of equipment operating in the facility and not the utility.
