lightning protection

Similarly, lightning arresters have been observed in the temples built in ancient kingdom of Anuradhapura in Sri Lanka that date back to thousands of years. Early Streamer Emission or ESE Lightning Arrester is one of the prime categories of lightning arresters. The main objective of the Earthing electrode is to link to the general mass of the earth. This device is also well known as the surge arrester having a high voltage terminal along with a ground terminal. Back-fill Compounds are another source of Earthing using an amalgamation of natural earth minerals that consist of a hydroscopic quality to retain the moisture for a reasonably long time. The Moghul Emperor, Shah Jehan would have anticipated this kind of natural calamity that prompted him to take preventive action against lightning strokes. Earth rods are metal shafts utilized for grounding. Array of Arresters There are a large number of lightning Lightning Rodarresters such as ESE Lightning Arrester, Gel Earthing, Earthing Electrodes and Earth Rods.

A Historical View Lightning Arresters go back in time to the ancient days when massive structures built by the royal kings and emperors were prone to bolts of lightning. Ever since the 1970 Coupling, Metal Oxide Varistors or MOVs have been used for power systems. A Lightning Arrester is a safety device used on electrical power systems to provide protection to # the insulation system in order to withstand the damaging effect of lightning strokes. Safety - A Primary Concern One can easily visualize the extent of havoc and damage caused to property and lives with a stroke of lightning measuring millions of volts passing down from the sky to the earth.

Gel Earthing is a chemical based lightning arrester that using metal alloys and chemical compositions to counteract the lightning strike. It was a natural catastrophe which was envisioned by them. These rods are used providing earth facility for high rise buildings. Earthing Electrodes are based on the principle considering the general mass of earth as a reference zero potential; therefore, everything linked directly to it would at this zero potential or above by the amount of the volt drop in the connection system.net. No sooner a bolt of lightning strikes a building, the surge passes down the power system to the arrester which is diverted around the protective insulation down to the earth.alfredkim.

If you have visited the Taj Mahal in Agra, one can observe a strip of copper running down from the top of the main dome on the outside the monument and passing right through into the earth, which is a lightning arrester. It is always prudent to be wise in investing in an effective Earthing system, rather than feel sorry later since the damage from lightning strokes could be irreparable. This assists in maintaining a balance and consistency of the ohm value within safety norms without any fluctuations thereby safeguarding the equipment

For instance, the buyer must consider how much power the rig has and what kind of rig they intend to use with the pipe.. It is important to make sure that the drill pipe being purchased is strong enough for a particular rig or even for the particular application one has in mind.
The above tips can help you make the right purchase and extract the most out of your purchase.

This hardy, handy tool may not get all the attention it really deserves, but one cannot deny that it plays a vital role in the success of a project, or its failure!

The drill pipe may be the unsung hero at the drilling rig but it is expensive equipment and it does cost money. Maintenance can maximize the life of the drill pipe.

It is important to use the right grade of pipe. If the pipe and the rig do not match in size, the buyer is in for a lot of headaches besides waste of money. Another important tip is to rotate the drill rods in the rod basket so that the same rod is not the first one to go into the ground always. Some contractors tend to be a little shortsighted here, but one cannot get away with low quality pipe all the time.

Since drill pipes are expensive, it is important to take good care of them. A low quality pipe leads to a lot of fatigue resistance and this factor is highly critical in the drilling industry as the torque limits of the pipe is pushed right to the edge. Even simple actions like rod inspection and regular cleaning yield good results. If the quality of the pipe is low, disaster can strike at any moment. Just as people conduct research while purchasing other products, the same must be done in the case of a drill pipe too.

For more information on drill pipe, it is recommended that you visit one of the best companies. Since the drill pipe is among the most expensive wear item for drilling jobs, buying it and maintaining it is a necessity.

So, the demand for drill pipes is pretty high, and there are some factors to keep in mind before buying a drill pipe.

When flat bar Manufacturersbuying China ground Manufacturersdrill pipes, a percentage of customers always go with the price factor. Tough conditions can test the strength of the pipe. However, buying cheap may not always be a great idea when it comes to a tool like the drill pipe.

There are different kinds of drill pipes that one may buy, ranging from the most common integral forged pipe to the press and fit type.

A drill pipe is the backbone of any directional drilling project. A string of drill pipe could be extremely expensive, sometimes costing $25,000 or more (depending on the size, of course)

Components of utility poles include: Static wire, grounding conductor, Aphase Bphase Cphase, transmission, supply space, primary, step down transformer, multi grounded neutral, distribution, secondary service drop- to load, communication worker safety zone, communication space, communication lines, utility pole, vegetation, ground rod. Certainly, it is essential that you make sure that the treated poles are sturdy and preferably made from right trees and are of accepted standards. It can also be made of steel, concrete and fiberglass compound; there are also wooden poles available in the market and its life time is about 30-40 years.
4) The standard telephone pole height was 25 feet in the year 1876
5) The 1st telegraph poles transpire because the results of trialing by Samuel Morse, whose 1st try at resting underground cable between Washington, D. This monitoring by computer ensures that the quality standards of the wood are maintained and the timber poles are endowed with greater durability and longer life. and Baltimore, failed.

The seemingly simple timber poles abundantly found everywhere takes many years of preparation- right from the initial stage of growing the trees to final treatment before becoming serviceable.
