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 general, DC surge protection can provide significant benefits and advantages, especially in scenarios where the equipment is sensitive to voltage fluctuations or where there is a high risk of power surges. Benefits of DC Surge Protection Protection of Sensitive Equipment: Many electronic devices, especially those using DC power supplies, are sensitive to voltage fluctuations. Power surges […]
When it comes to electrical safety, there’s nothing more important than having the proper circuit protection in place. Whether you’re dealing with a commercial or residential application, DC Mini Circuit Breakers (DC MCBs) can provide important benefits and peace of mind. DC Mini Circuit Breakers (DC MCBs) are widely used in solar system. DC power is commonly […]
Connections of a SPD to the loads should be as short as possible in order to reduce the value of the voltage protection level (installed Up) on the terminals of the protected equipment. The total length of SPD connections to the network and the earth terminal block should not exceed 50 cm. One of the […]
