How do you use the rolling sphere method?
In this method, the air terminals are placed by rolling an imaginary sphere around and on top of the structure to be protected in all the possible directions. The sphere should not make any contact with the structure to be protected and touches only the air termination system and the ground.
How can you protect your equipment from lightning strikes?
How to Protect Electrical Appliances From Lightning Strikes
- Install a plug-in, point-of-use electrical surge protector, advises Century Link.
- Use plug-in surge protectors for telephone and cable TV lines.
- Install a service-entrance surge protector to protect your entire house from voltage surges.
How do you determine lightning protection level?
LPL refers to the case of maximum surge current, based on the 10/350μs pulse current waveform, which is applied to the case of Type I protectors used in power entry level into a building.
What is protective angle method?
Protection Angle Method is the conventional method of providing protection to the structures. In this method the air terminals are placed at the top of the structure to be protected.
What is a rolling sphere?
The Rolling Sphere Method is an aid to identify the areas of a building or structure that needs protection using air termination rods. This method also takes into account the possibilities of strikes to the side of the building.
What is the best way to protect electronics?
There are three main strategies for preventing surge damage:
- Unplug your electronics when not in use.
- Use surge protection power strips.
- Install whole-home surge protection.
How do lightning protection systems protect structures?
A lightning protection system is designed to protect a structure from damage by intercepting such strikes and safely passing their extremely high voltage currents to “ground.” This system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground …
How does lightning protection system work?
A lightning protection system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground for potential strikes. Lightning protection systems are used to prevent lightning strike damage to structures.
Why is lightning protection needed?
There are many ways in which lightning strikes can cause damage or injury. Lightning strikes (or even electrical discharges due to nearby lightning) can cause fires, explosions, chemical release or mechanical disruption within or around a building.
