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
Surges may be caused by an indirect lightning strike but, the majority are caused by equipment being turned on or off within a facility. These surges damage components costing money to repair or replace as well as create unplanned downtime resulting in unfulfilled orders, missed deadlines, unreliable systems and/or dangerous situations. The GHX Surge Protective Device (SPD) Series for […]
GENERAL INFORMATION of Type 1-Voltage Limited Type Surge Protective Device(SPD) l Varistor surge protective device (AC SPD) l Large discharge energy. l No leakage and no follow current. l Applied to surge protection at the first stage of the power supply system. l Strong environmental resistance. l DIN rail installation.
The Importance of Surge Protection Devices The capacity of a PV array is directly related to its exposed surface area, so the potential impact of lightning events increases with system size. In the area that lighting occurrences are frequent, unprotected PV systems could suffer repeated and significant damage to key components. It results in substantial […]
