Means of protecting electrical systems, buildings, and different property from lightning and different high-voltage surges. Lightning protection systems have changed extensively with the passage of time. New appliances, electronic and all the varieties of home and different building construction equipments ought to 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 different disasters annually.
A lightning protector provides a protection against lightning. Lightning protection system can not stop lightning to strike however it will defend the equipment from spoil. On the other hand a lightning surge protector may be a device that protects electronic devices from surge in electrical power. Surge protectors are commonly known as power strips, surge suppressors and transient suppressors.
One hundred twenty volts are a normal voltage for homes and alternative buildings in most of the countries including United State of America. Voltage over this customary will cause injury to the equipments. A surge protector channels the over voltage into the wires of outlet that prevent the additional flow of voltage through the devices and let the normal voltage to flow in its.
Conceptually, lightning surge protection devices are switches to earth. Once a threatening surge is detected, a lightning protector 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 components used as protecting switches are: gas tubes, metal oxide varistors and silicon avalanche diodes (transorbs). Each has bound benefits and disadvantages.
From studies of lightning, there are two conclusions: (1) Lightning won\’t strike an object if it\’s placed in a grounded metal cage. (2) Lightning tends to strike, in general, the tallest objects on the horizon.
The possibility that a object will be struck by lightning is less if it is located under a valley. Therefore, electric transmission lines that should cross mountain ranges often will be routed through the gaps to avoid the direct exposure of the ridges.
There are a variety of protecting devices to limit or prevent lightning harm to electric power systems and equipment. The word protective is used to denote either one of two functions: the prevention of trouble or its elimination once it occurs. Different protecting means that are taken either to prevent lightning from getting into the system or to minimize it\’s harmlessly if it does. Overhead ground wires and lightning rods are used to stop lightning from striking the electrical system. Lightning arresters are protective devices for reducing the transient system over voltages to levels compatible with the terminal-apparatus insulation.
Underwriters Laboratories Inc. (UL) has been operating within the lightning protection field for the last 100 years. Their expertise in the safety testing field has gain recognition worldwide. UL Mark on merchandise and systems is that the mark of level for safety. Underwriters\’ laboratories Inc. is working in the area of factory testing and inspection of the system components 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.
