Comparison between lightning arresters and lightning rods (arrester manufacturers)
Concept difference:
A lightning arrester is an electrical appliance used to protect electrical equipment from the hazards of high transient overvoltage and to limit the freewheeling time and often the freewheeling value; the lightning rod, also known as a lightning protection rod, is a device used to protect buildings, tall trees, etc. from lightning strikes.
Type differences:
Lightning rods mainly include direct lightning rods, special lightning rods, advance pre-discharge lightning rods, etc.; lightning arresters are divided into metal oxide arresters, line-type metal oxide arresters, andGap line type metal oxide arrester,Gapless line type metal oxide arrester, fully insulated composite jacket metal oxide arrester, detachable arrester, etc.
Differences in scope of application:
Lightning arresters are suitable for overvoltage protection of transformers, transmission lines, distribution panels, switch cabinets, power metering boxes, vacuum switches, parallel compensation capacitors, rotating electrical machines and semiconductor devices.
Principle difference:
The lightning protection of a lightning rod is that it can lead lightning from above the protective object to itself and safely discharge it into the earth through itself. Therefore, its lightning inducing performance and discharge performance are crucial; the role of the lightning arrester is to protect various electrical equipment in the power system from damage caused by lightning overvoltage, operating overvoltage, and power frequency transient overvoltage impact.
