DC SPD applied to the Din rail type protects the DC electric system from surge. Also, the system allows replacement of the protective element (MOV), ensuring convenience and reduced cost. However, as only the protective module is provided, other components should be added when the system is installed in accordance with the site condition.
Overvoltage may occur in electrical installations for various reasons. It may be caused by: 1. The distribution network as a result of lightning or any work carried out. 2. Lightning strikes (nearby or on buildings and PV installations, or on lightning conductors). 3. Variations in the electrical field due to lightning. Like all outdoor structures, […]
Surge protective decives, also known as lightning arresters, are electronic device that provide safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication lines due to external interference, thesurge protective decives can conduct the shunt in a very short period of […]
SPDs’ operating characteristics are defined by several technical characteristics. The following are some technical characteristics that should be considered: maximum continuous operating voltage, ac or dc application, nominal discharge current (defined by a magnitude and waveform), voltage-protection level (the terminal voltage that is present when the SPDs are discharging a specific current) and temporary overvoltage […]
