Tips: What is a surge protection device?
• The surge protection device (SPD) is an electronic device that provides a protection for electrical equipment, communication network etc. from the effect of surges. When a current spike or voltage surge suddenly occurs in an electrical circuit or a communication line due to external interference, the SPD can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit.
• Surge protective devices are designed to minimize the effects of the indirect and direct lightning or other transient overvoltage surges, suitable for surge protection in residential, tertiary industrial and other industrial applications. SPD has several protection modes: L-L, L-G, L-N, N-G and its combinations.
• The SPD surge protector is an indispensable device for lightning protection in the electronic equipment. Its role is to restrict the transient overvoltage that enters the power line and signal transmission line to the voltage range that the device or system can withstand, or to discharge powerful lightning current into the ground, thus to protect the equipment or systems from shocks.
A Surge Protective Device (SPD) operation is by limiting transient overvoltages and diverting surge currents to ground, preventing damage to electrical equipment.
