With the widespread use of modern electronic equipment, demands for the stability and reliability of power networks continue to rise. As an effective device for protecting electrical equipment, surge
Both lightning arresters and surge protective device are designed to shield electrical equipment from sudden voltage fluctuations, but they differ in several key ways: Working Principle Lightning arre
Power cables should implement multi-level protection. This multi-level approach uses each lightning protection zone as a tier, progressively attenuating lightning energy (energy distribution) to ensur
The selection of other parameters for surge protective device depends on the level of the lightning protection zone where each protected object is located, and its operating voltage is based on the ra
The subsequent evaluation model is used to assess the lightning current distribution at the boundary of protection zones after LPZ1. Since the user-side insulation impedance is much greater than the i
The distribution of lightning current among various facilities entering the building is as follows: approximately 50% of the lightning current is discharged to the ground through external lightning pr
Surge protectors, also known as equipotential bonding devices, overvoltage protectors, surge suppressors, surge absorbers, and lightning protection devices, are used for power line protection. Given t
surge protective device is generally connected in parallel in the power supply system. When lightning occurs in the middle of summer, it will induce ultra-high voltage and overcurrent on the power sup
