Means of protecting electrical systems, buildings, and other property from lightning and different high-voltage surges. Lightning protection systems have changed extensively with the passage of time. New appliances, electronic and all varieties of home and other building construction equipments should be protected from lightning. Lightning can hit anywhere within the world. Every year hundreds of homes and alternative buildings are destroyed by the lightning. Lightning damages not only property and causes death than any other disasters yearly.
A lightning protector allows a guard against lightning. Lightning protection system can not stop lightning to strike but it will defend the equipment from damage. On the other side a lightning surge protector is a device that protects electronic devices from surge in electrical power. Surge protectors are also commonly referred to as power strips, surge suppressors and transient suppressors.
120 volts are a customary voltage for homes and alternative buildings in most of the countries including United State of America. Voltage over this standard can cause harm to the equipments. A surge protector channels the over voltage into the wires of outlet that forestall the extra flow of voltage through the devices and let the conventional voltage to flow in its.
Conceptually, lightning surge protection devices are switches to earth. Once a threatening surge is detected, a lightning protection equipment grounds the incoming signal association point of the equipment being sheltered. Therefore, redirecting the threatening surge on a path-of-least resistance (impedance) to ground where it is absorbed.
The essential parts used as protective switches are: gas tubes, metal oxide varistors and silicon avalanche diodes (transorbs). Each has bound advantages and disadvantages.
From studies of lightning, there are two conclusions: (1) Lightning will not strike an object if it’s placed in a grounded metal cage. (2) Lightning tends to strike, generally, the tallest objects on the horizon.
The prospect that a object will be struck by lightning is smaller if it is located in a valley. So, electric transmission lines which should cross mountain ranges often can be routed through the gaps to avoid the direct exposure of the ridges.
There are many types of protecting devices to limit or protect lightning harm to electrical power systems and equipment. The word protective is used to denote either one of two functions: the prevention of hassle or its elimination after it occurs. Different protective means that have been taken either to protect lightning from entering the system or to attenuate 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 protective devices for reducing the transient system over voltages to levels compatible with the terminal-equipment insulation.
Underwriters Laboratories Inc. (UL) has been working within the lightning protection field for the last one hundred years. Their experience in the security testing field has gain recognition worldwide. UL Mark on products 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 field 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.
