Introduction
The operation of industrial, commercial, and infrastructure facilities is dependent on delicate electrical devices including control panels, PLCs, computers, transformers, communications networks, and automated devices. In the event of lightning strike and switching events, electrical surges are produced, resulting in damages to great extent of the equipment, downtime, safety concerns, and disruptions.
What Is Nominal Discharge Current?
Nominal discharge current, commonly represented as In, is the peak current that a surge protection device can safely discharge several times under standardized test conditions. It is generally measured using an 8/20 microsecond current waveform and expressed in kiloamperes.
A higher nominal discharge current does not automatically mean that a device is suitable for every application. Selection should consider the facility location, lightning exposure, electrical distribution system, equipment sensitivity, and coordinated protection requirements.
