Lightning is a remarkable natural occurrence that can be both harmful and destructive at the same time as thrilling. Both the voltage and the current are quite high. Therefore, to safeguard electric power equipment, buildings, aircraft, and boats, we employ a variety of protective strategies, tactics, and tools, including ground wires, lightning rods, and lightning arresters.
Lightning strikes may do terrible harm; you may have witnessed trees burning as a result of lightning strikes. As a result, lightning protection is required for all electrical equipment in power plants, substations, and overhead power lines. You may have seen tall structures with a sharp rod fixed to the top. This is referred to as an earth rod or lightning rod. To prevent lightning from going through the structure and instead grounding itself when it strikes, the best Lightning Arrester Manufacturer in India offers the lightning arrestor to the entire facility.
Typically, towers supporting overhead transmission lines are positioned above overhead ground wires, also known as earth wires. Earth screens are typically employed to safeguard substations and power-producing facilities. All electrical equipment has many copper conductors that offer an inexpensive route toward the ground in circumstances of lightning strikes.
Lightning Arrester Types
The Lightning arrester for home comes in a variety of varieties that are employed in various contexts. Among the well-liked varieties are:
- Rod Gap Arrester (Spark Gap Arrester)
- Horn Gap Arrester
- Sphere Gap Arrester
- Multigap Arrester
- Electrolytic Type Arrester
- Expulsion Type Arrester
- Lead-Oxide Type Arrester
- Valve Type Arrester
- Thyrite Lightning Arrester
- Pellet Type Arrester
- Impulsive Protective Gap with Electrolyte Arrester
- Metal Oxide Arrester
The following qualities are excellent for a lightning arrester:
- In other words, under typical working conditions, it shouldn’t drain any current; instead, the spark-over voltage ought to be higher than the system’s potential abnormal power frequency.
- To provide a conducting channel to the ground, any transient anomalous voltage over the breakdown value must cause it to break down as soon as feasible.
- It should be able to support the discharge current that results from the breakdown without suffering damage from it or having the voltage across it go over the breakdown value.
- As soon as the transient voltage drops below the breakdown value, the power frequency current that followed the breakdown must be cut off.
A Lightning Arrester: What Is It?
Every safety mechanism that we have previously observed shields against direct lightning strikes. However, they are not very successful in stopping traveling waves. Here’s where Lightning Arresters become useful. The best Lightning Arrester Manufacturer in India offers a simple route for the lightning surge power to get to earth and is typically erected atop transmission poles and structures.
How Does Flashlight Arrestor Function?
The fundamental design of a lightning arrester consists of a spark gap and a series resistor. Non-linear resistors, or resistors whose resistance is inversely proportional to the voltage that is, declining as the voltage rises and rising as the voltage falls come to mind when we discuss resistors. So, in the case of a lightning strike, the high surge voltage will drop the voltage of this resistor, resulting in a low resistance route to the ground.
