How to install and apply lightning protection grids? 1. Where is the lightning protection grid installed? What determines whether a lightning protection grid needs to be installed? What is the wiring sequence for the field instruments after they come from the junction box? 2. After installing lightning protection grids, do the instruments on site still require lightning protection? 3. Which signals require lightning protection? Do the signals from the MCC supplied by electricity need lightning protection? 4. What other lightning protection measures is the system required to have in addition to the lightning protection grid?
Why isn’t anyone participating in this question? Perhaps it wasn’t seen. I’ll give it a try.
:funk: What is a lightning protection grid :sleepy:
Shenzhen Kerui Technology Co., Ltd. 13302977826 – Lightning protection grids, also known as surge protectors, are widely used in lightning protection to safeguard electrical and electronic equipment. Typically, these devices are located within the Lightning Protection Zone (LPZ), with a few being in LPZ0B. The function of a lightning protection grid is to limit surges in the circuit and, in combination with the shielding structure, to create a protective environment with a low electromagnetic field. Functions of the lightning protection grid: 1. Diverting surge currents and suppressing surge voltages. The function of the lightning protection grid is to establish a transient equipotential connection for those charged conductors in electrical and electronic systems that cannot be directly connected at equal potential using conductors. By taking advantage of the nonlinear properties of the lightning protection grid, it is possible to limit transient surge overvoltages and divert surge currents, thereby protecting electrical and electronic systems. 2. The lightning protection grid and shielding structure are used to create a lightning protection zone (LPZ); the live conductors entering and leaving the shielding structure (power lines, signal lines) are connected to each other at the same potential using the lightning protection grid. The lightning protection grid and the three-dimensional shielding structure together form the LPZ, with SPDs being important components for defining the boundaries of the LPZ. The surges in the conductors of the LPZ are diverted at the boundary, resulting in the attenuation of the electromagnetic fields within the LPZ area.
