Class II Lightning Protection Type 2 SPD 40Ka Surge Protective Devices Application:
• Surge protection devices (SPDs) are suitable for the TN-S power supply system of 50/60Hz
• Suitable for three phase application
• Protecting them from direct and indirect lightning impulse and other transient overvoltage.
Installation:
• The type 2 arresters must install into sub-distribution boards after main distribution boards containing type 1 arresters.
• For proper operation between type 1 and type 2 arresters at least 10- 15 m cable or wire must be otherwise a decoupling coil have to install between the two devices.
• Multiple surge diverters installed in a cascaded approach should be used to ensure adequate protection of the facility.
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.
