Lightning arrester: what is its purpose? A lightning arrester is used along power lines outside a housing, usually next to a transformer. Lightning If lightning strikes during a storm, a high-voltage current flows through the wires and provides relief. Lightning arresters quickly divert electrical surges from around your home to the earth or ground. Lightning arresters are also classified according to their function. Whether you need single-phase or three-phase lightning protection, there are several classes to choose from. Lightning arrester Features and Functions: Even a normally operating lightning arrester will quickly deteriorate if exposed to an abnormal voltage that exceeds its rated breakdown value. "Failure" refers to the ability of a lightning arrester to momentarily break its internal insulation, allowing a voltage surge to flow to the earth. The current must be diverted precisely when the transient voltage reaches the rated breakdown threshold. The sparkover voltage must exceed the average power frequency coming into the system for the device to operate. There should be no conductivity under normal conditions. Finally, the lightning arrester for building must conduct the discharged electrical energy without losing durability in the event of these failures. How do lightning arresters work? Lightning arresters do not protect your home or business from lightning strikes. They are typically installed between power lines and your home, substation, or circuit breaker. A lightning rod differs from a lightning arrester in that it is a passive rod that absorbs lightning strikes and conducts them to the earth through an attached cable. Even when using only lightning rods, there is a risk of a sudden power surge affecting electrical circuits. A lightning arrester for home has a high-voltage terminal and an earth terminal. Particles of electric current naturally try to flow through electrical components. This is where lightning arresters come in handy. Lightning arresters divert excess current to a designated location. Power Cable Corporation offers is a high- Lightning arrester containing equipment to regulate and distribute electrical energy. Some substations are small, consisting of only a transformer and associated switches, while others are large and complex. |
arrester has a metal spiral shape placed on railway tracks to protect nearby electrical systems.
