CNKA dc lightning surge arrester FAQ
Q: How does a solar surge protector work?
A: A surge protector serves as a safeguard against electronics damage by redirecting excess electricity from the "hot" power line into a grounding wire. This is accomplished using a metal oxide varistor (MOV) in most standard surge protectors, which consists of a metal oxide linked to the power and grounding lines through two semiconductors.
Q: What are surge protection devices for PV?
A: In order to ensure the safety and protection of both household and large-scale PV installations, it is important to adhere to specific design protocols. Key measures such as the installation of lightning arresters and surge protection devices (SPDs) should be implemented to proactively safeguard the system and prepare for potential power surges.
