The Way Of Lightning Protection
February 10, 2010
Meanings of protecting electrical systems, buildings, and alternative property from lightning and alternative high-voltage surges. Lightning protection systems have changed extensively with the passage of time. New appliances, electronic and all the types of home and alternative building construction equipments should be protected from lightning. Lightning will hit anywhere within the world. Every year many homes and different buildings are destroyed by the lightning. Lightning damages a lot of property and causes death than any other disasters yearly.
A lightning protector provides a shield against lightning. Lightning surge protection can not stop lightning to strike but it will protect the equipment from damage. On the other side a lightning surge protector may be a device that protects electronic devices from surge in electrical power. Surge protectors also are commonly referred to as power strips, surge suppressors and transient suppressors.
120 volts are a standard voltage for homes and different buildings in most of the countries among United State of America. Voltage over this standard will cause injury to the equipments. A surge protector channels the over voltage into the wires of outlet that forestall the additional flow of voltage through the devices and let the conventional voltage to flow in its.
Conceptually, lightning surge protection devices are switches to ground. Once a threatening surge is detected, a lightning protection equipment grounds the incoming signal affiliation point of the equipment being sheltered. Thus, redirecting the threatening surge on a path-of-least resistance (impedance) to ground where it is absorbed.
The basic elements used as protective switches are: gas tubes, metal oxide varistors and silicon avalanche diodes (transorbs). Each has certain advantages and disadvantages.
From studies of lightning, there are 2 conclusions: (1) Lightning will not strike an object if it’s placed under a grounded metal cage. (2) Lightning tends to strike, generally, the tallest objects on the horizon.
The prospect that a thing will be struck by lightning is smaller if it is located in a valley. Thus, electrical transmission lines which must cross mountain ranges usually can be routed through the gaps to avoid the direct exposure of the ridges.
There are a number of protective devices to limit or protect lightning damage to electrical power systems and equipment. The word protecting is used to denote both of two functions: the prevention of trouble or its elimination once it occurs. Different protecting means have been taken either to prevent lightning from coming into the system or to minimize it’s harmlessly if it does. Overhead ground wires and lightning rods are used to prevent lightning from striking the electrical system. Lightning arresters are protecting devices for reducing the transient system over voltages to levels compatible with the terminal-apparatus insulation.
Underwriters Laboratories Inc. (UL) has been operating in the lightning protection field for the last 100 years. Their expertise in the protection testing field has gain recognition worldwide. UL Mark on merchandise and systems is that the mark of level for safety. Underwriters’ laboratories Inc. is operating in the section of factory testing and inspection of the system elements and the sector inspection parts of completed installation.
Global Lightning Technologies (M) Sdn. Bhd. has its origin that dates back to 1986, when Lightning Protection division of DOM Industries (M) Sdn. Bhd. was first set-up. As a result of strong growth and an increasing demand in this sector it was decided that this division of DOM Industries become a separate entity to focus primarily on Lightning Protection Systems.
