Lightning arrester - Wikipedia
A lightning arrester (alternative spelling lightning arrestor) (also called lightning diverter) is a device used on electric power systems and telecommuniion systems to protect the insulation and conductors of the system from the damaging effects of lightning.The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which
The transition from gapped silicon carbide arresters to MOV type gapless arresters was rapid. All the US manufacturers of surge arrester could see that the future of the business lay in investment in zinc oxide technology and production of this new semi-conductor. The transition was positive for some and not so for others. McGraw
IEC 61051-1:2018 is a generic specifiion and is applicable to varistors with symmetrical voltage-current characteristics for use in electronic equipment. It establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifiions for quality assessment or any other purpose.
