Photovoltaic aluminum bracket can be used as lightning protection grounding

Can a PV power plant be protected by a lightning rod?

With the bond- overvoltage in the system. It is highly recommended to be adopted in the PV power plant protected by independent lightning rods. photovoltaic (PV) power plant. I. I NTRODUCTION tion for electric power systems. Numerous studies have systems during lightning strikes. It is found that soil stratifi-

Can a dedicated grounding grid improve lightning protection?

Installing a dedicated grounding grid, which is very costly in a large PV power plant, can reduce the amplitude of the transferred voltage and eliminate the residual voltage effectively. It is found that the arrangement using a bonding network is superior to other grounding improvement approaches in lightning protection.

Is lightning protection necessary for PV systems?

Consequently, effective lightning protection is indispensable for PV systems. Lightning transient evaluation of a PV system has been a necessary task in designing effective LPS. Such evaluation has been addressed experimentally and numerically. Stern and Karner [ 10] investigated the induced voltages of a single panel in the laboratory.

How to reduce overvoltage between DC cable & PV bracket?

overvoltage between the dc cable and the PV bracket. Much in the air. The ov ervoltage can be further reduced by placing the bonding conductors in the middle of two dc cables in the air. better lightning protection performance than a grounding mesh. does not worsen the performance of lightning protection. On when the soil resistivity is high.

Do lightning rods need a grounding grid?

grounding grid for the lightning rod is not necessary. in some standards. However, such interconnection may largely PV bracket when the soil resistivity is high. It will not improve the situation even if the soil resistivity is lo w. The connection of shock during a fault condition or a lightning strike.

How to reduce Lightning overvoltage in a PV array?

S YSTEM WITH EQUIPOTENTIAL BONDING IN THE AIR reduce the lightning overvoltage in a PV array significantly. stiff soil. On the other hand, as the prices of PV panels and PV power plants. Reducing the installation and construction PV power plants. Installing the grounding grid no matter in undoubtedly increase the total investment cost.
