In spite of the high lightning risk that many PV installations are exposed to, they can be protected by the application of DC SPDs and a properly engineered lightning protection system. Effective DC SPD implementation should include the following considerations:
•Correct placement in the system
•Termination requirements
•Proper grounding and bonding of the equipment-ground system
•Discharge rating
•Voltage protection level
•Suitability for the system in question, including dc versus ac applications
•Failure mode
•Local and remote status indication
•Easily replaceable modules
•Normal system function should be unaffected, specifically on non-power systems
In lightning protection products, surge protectors and arresters are widely used. Both are important components to protect electronic equipment. There are also fundamental differences. Let us first see what these two lightning protection products are. The surge protector is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range […]
In protecting electrical equipment from power surges and other electrical disturbances, Surge protective devices play a crucial role . But with so many options available, how do you choose the right surge protective device for your needs? 1. Determine your Needs The first step in selecting an SPD is to determine your needs. What equipment […]
In today’s world, electronic devices are an integral part of our everyday lives, and their importance continues to grow. We use them for work, communication, entertainment, and even education. However, these devices are vulnerable to damage caused by power surges. Surge protective devices (SPDs) have become increasingly important to protect our electronic devices. In this article, we […]
