Flash Facts About Lightning. A moving thunderstorm also gathers positively charged particles along the ground that travel with the storm. As the differences in charges continue to increase, positively charged particles rise up tall objects such as trees, houses, and telephone poles—and people. When the charge gets close to the ground, it is attracted by all the positively charged objects, and a channel develops. The subsequent electrical transfer in the channel is lightning. That's not a good sign! Your best bet is to get yourself immediately indoors. Since light travels faster than sound, the thunder is heard after the lightning. If you see lightning and hear thunder at the same time, that lightning is in your neighborhood. Lightning conductor definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. MATA et al.: EMTP MODELING OF A TRIGGERED-LIGHTNING STRIKE TO THE PHASE CONDUCTOR OF AN OVERHEAD DISTRIBUTION LINE 1177 Fig. Transmission line sections used in the model. Arresters Non-linear resistor type-92 is used to. If you see successive strokes of lightning in the same place on the horizon then you are in line with the storm, and it may be moving toward you. Some lightning originates in the top of the thunderstorm, the area carrying a large positive charge. Lightning from this area is called positive lightning. It can strike as far as 5 or 1. The determining factor on whether a particular flash could be deadly depends on whether a person is in the path of the lightning discharge. Although some victims are struck directly by the main lightning stroke, many victims are struck as the current moves in and along the ground. Seek shelter and avoid situations in which you may be vulnerable. When you see lightning, count the time until you hear thunder. If that time is 3. Seek shelter immediately. Wait at least 3. 0 minutes after the last clap of thunder before leaving shelter. Full line of Lightning Protection Equipment, Surge Arresters and Directions for Self Installation. We carry residential and commercial lightning equipment.What is the minimum size of down conductor for lightning protection? What is the individual resistance and combine resistance of electrode? What is the resistance of grounding network? Don't be fooled by sunshine or blue sky! People involved in activities such as boating, swimming, fishing, bicycling, golfing, jogging, walking, hiking, camping, or working outdoors all need to take the appropriate actions in a timely manner when thunderstorms approach. In summer, especially on a holiday, more people are outside, on the beach, golf course, mountains, or ball fields. Outdoor jobs such as construction and agriculture, and outdoor chores such as lawn mowing or house painting are at their peak, putting people involved in danger. Swimming is particularly dangerous, as not only do swimmers protrude from the water, presenting a potential channel for electrical discharge, but also because water is a good conductor of electricity. As with the outdoor activities, these activities should be avoided before, during, and after storms. Most people hurt by lightning while inside their homes are talking on the telephone at the time.

Lightning Protection – Introduction Structural lightning protection design considerations BS 6651 (Protection of structures against lightning) clearly advises strict adherence to the provision of a conventional Lightning. Lightning Conductor Cable’s. Class 1—Standard of the industry for buildings under 75’ high (Other sizes available). Copper Conductor Cable: Catalog #C-1 Copper $2.35 per ft. Lightning is caused by the build up of electrostatic charge in clouds. One region within the cloud builds up a positive charge and the other a negative charge. The process is not completely understood as to why. Cardiac arrest and irregularities, burns, and nerve damage are common in cases where people are struck by lightning. However, with proper treatment, including CPR if necessary, most victims survive a lightning strike, although the long- term effects on their lives and the lives of family members can be devastating. For a shelter to provide protection from lightning, it must contain a mechanism for conducting the electrical current from the point of contact to the ground. These mechanisms may be on the outside of the structure, may be contained within the walls of the structure, or may be a combination of the two. Inside a structure, lightning can follow conductors such as the electrical wiring, plumbing, and telephone lines to the ground. Many small open shelters on athletic fields, on golf courses, in parks, at roadside picnic areas, in school yards, and elsewhere are designed to protect people from rain and sun, but not lightning. Small wooden, vinyl, or metal sheds offer little or no protection from lightning and should be avoided during thunderstorms. Regardless of the method of entrance, once in a structure, the lightning can travel through the electrical, phone, plumbing, and radio or television reception systems. Lightning can also travel through any metal wires or bars in concrete walls or flooring. Lightning can travel long distances in both phone and electrical wires, particularly in rural areas. In general, basements are a safe place to go during thunderstorms. However, avoid contact with concrete walls, which may contain metal reinforcing bars. If you plan to unplug any electronic equipment, do so well before the storm arrives. Do not wash your hands, do not take a shower, do not wash dishes, and do not do laundry. Tall buildings and monuments are frequently hit by lightning. Avoid being near a lightning rod or standing near metal objects such as a fence or underground pipes.
