A signal surge protector is a type of surge protection devices that is linked in series on a signal line to reduce transient over-voltages and deflect surge currents away from the signal line. Signal ...

A surge protector, also called as surge diverter, surge suppressor, or surge protection device (SPD), is an appliance designed to protect electrical devices from induced lightning.1. How about the sur...

1. Type 1 lightning protectionThe aim is to prevent voltage surge from being directly conducted from LPZ0 to LPZ1 and limit the voltage surge varying from tens of thousands of volts to hundreds of tho...

1. What's a surge protection device (SPD)?A surge or spike refers to a transient over-voltage that is far larger than the specified operating voltage. In essence, it is a strong impulse with the d...

2.1.20 Reference Voltage UrefIn the area where the volt-ampere characteristics of the metal oxide resistor will transition from the weak electric field area to the strong electric field area, a suitab...

2.1 Technical Term2.1.1. Lightning electromagnetic impulse (LEMP)It is a source of interference. Refers to the effect caused by lightning directly hitting the lightning protection device of a building...

Surge Protective Device is a device designed to protect against transient overvoltages, serving as an important component of the internal lightning protection system. According to its specific usage, ...

Since the energy of lightning strikes is very huge, it is necessary to gradually discharge the energy of lightning strikes to the ground through a hierarchical discharge method. The first-level lightn...
