Locating That Underground Cable Fault

Monday, August 24th, 2015

There are hundreds of cables buried beneath the ground. A repair on one of those buried lines used to be like finding a needle in a haystack, but not anymore. Cable faults can now be spotted very easily using modern detection technologies. Cable locators and detection technologies make the task less time-consuming and much easier than before.

When locating cable faults, one must have a certain set of skills necessary to do the job without damaging the cables. There are several methods in cable fault finding. You can sectionalize the cable or divide it into small cables and test it. Thumping (inducing a high voltage current to the cable) will cause the faulty part of the grid to make a loud noise. However this may cause degradation on the rubber insulations. Time Domain Reflectometry (TDR), sends a low-energy signal that causes no damage to the insulations but the results are not completely reliable. However the result can be used to decide whether thumping is needed in the area.

Other methods include High-voltage radar method, the surge pulse reflection method and the voltage pulse reflection method. Faulted cables produce electrical disturbances and these disturbances can be detected through these methods. Click here for the full article…

Use an underground cable locator to find buried cable

Monday, August 24th, 2015

About 40 years ago, locating used to be about finding buried waters, gas or sewer lines. Now, the telecom companies have joined in on these underground activities. Underground repairs for ripped cables can be a very difficult task. Cables can be found on top of cables and finding the right cable can be a very tricky job.

Cable locators are quite helpful as they can pinpoint the location of cables in need of repair. Cables emit some electromagnetic frequencies that are traceable. With the help of locators, there is no longer any need for backhoes to unearth buried cables.

A cable locator generally has 2 parts, a receiver and a transmitter that can be set into a specific frequency of the cable. There are different ways of transmitting signal into a cable, passive signals, direct connect general induction and inductive coupling. A receiver picks up the signal in peak, null and differential. Interpreting these signals can tell you the depths and locations of cables underground.

These cable locators make wiring repairs of buried cables and finding sewer lines, gas and water easy. New models now have screens so reading can be made easier. Read more about it here

Life Underground: Working in Tunnelling

Friday, August 21st, 2015

Tunelling is something that is most likely not among the top career choices for a lot of people since the job requires you to work underground in hot, cramped and dangerous working conditions. But tunnelling plays a very vital role in any major infrastructure construction. Maple Resourcing interviewed four men to share their experiences in tunnelling.
Frank Mimnagh has been a tunnelling engineer for the past 25 years. One of the highlights of his careers was working on the Cross Tunnel Rail Link. He is involved in giving insights and ideas on tunnel progress, assessing risks and commenting on the design.
Yoseph Ghetto is a materials engineer, and his first job was a tunnel geologist on a project in Ethiopia. He shares that safety is the most important part in tunnelling.
What Aimi Elias (a civil engineering graduate) enjoys about tunnelling is that you can go to unusual and unseen places.
While Caesar Entres, an implementation engineer, believes that tunnelling is not just a job. Even though the work is time-consuming, he finds it very rewarding. It is like building the foundation for the community.

All four agree that people in tunneling often form a community and support each other the way the tunnels they build support the infrastructures above. Click here to read their full stories…

Economic Impact of Investment in Pipeline Infrastructure

Thursday, August 13th, 2015

Natural gas is quickly overtaking the position of coal as the leading source of energy in the market with an annual consumption in 2012 totaling 25 trillion cubic feet. Approximately fifty percent of North America’s consumption is sourced locally and the remaining half is imported. This requires a system of pipeline, storage facilities and supply points to be setup domestically and has so far resulted in a network of about 305,000 miles of pipelines.

With the rise of demands from different sectors (household, commercial and industrial), the need for extensive infrastructure installations becomes more pressing. The forecast for 2025 is that investments on pipeline infrastructure will increase to $73.8 billion, which will provide employment, labor income, increased government revenues and input to GDP. This will also set a chain reaction of economic effects within the industry’s supply chain which benefits manufacturers of raw materials (like steel and machinery) as well as finished products (like pumps, compressors, reading instruments, etc.). As a whole, the increase demand results to a better job market for suppliers as they build up their work force, increased income and an increase in the demand of consumer goods and services forming a complete cycle of economic stimulation.

Pipelines would ease rail freight capacity for US farmers

Thursday, August 13th, 2015

During the 2014 harvest, the average corn farmer in North Dakota received US$10,000 less than the prevailing rate for the same crop in the market and resulted in a US$570 million profit cut for the region. The main reason for this loss is that rail freight transportation in America is highly congested due to the spike in rail transportation of crude oil. According to a study by the American Farm Bureau Federation (AFBF), the expansion of North America’s pipeline infrastructure (especially in the Bakken region) would alleviate the overburdened freight rail network and in effect improve services for farmers who are very dependent upon the rail freight system to move their products to market.

Since crude oil is more flexible when it comes to methods for transportation, moving the crude oil to the market using pipeline infrastructure would be more efficient and would also enhance the American energy security. The study used mathematical simulated scenarios on how expansion of any freight method reduces the bottleneck in delivering goods and as a byproduct it presented the increase of annual volume of grains transported by around 14 percent.

All You Need To Know About Tesla’s Big Battery Announcement

Wednesday, July 15th, 2015

Exciting news came from Tesla’s design studio in Hawthorne, CA, where two products were revealed that Tesla executives say will allow people, not surprisingly, to live completely off the grid. The products are part of a new storage business called Tesla Energy and consist of a home battery and a grid battery. The first product is called the PowerWall and is a rechargeable lithium-ion battery for the home that comes in two sizes: one for back up applications and the other for daily cycling application and prices range from $3000 to $3,500 which includes installation.

The second product is called the PowerPack that can be stacked to scale up to a gigawatt-class system, and while not as much information was available about this product, production is expected sometime during 2016. Telsa is growing rapidly with many partnerships including SolarEdge and Green Mountain Power, as well as Amazon’s Web Services, Target and Southern California Edison.

Mike Rowe Gave the Perfect Response After Being Accused of “Right-Wing Propaganda”

Friday, July 10th, 2015

Mike Rowe, former Dirty Jobs host and current host of ‘Somebody’s Gotta Do It’, is also very active on Facebook promoting his foundation that provides scholarships for trade jobs, mikeroweWORKS. Rowe is a firm believer in a ‘work smart and hard’ work ethic, and he feels strongly that if a person want’s to find work they can; that there are many unfulfilled jobs in America with hiring managers expressing frustration at the lack of potential candidates for their job openings. Being outspoken about his beliefs, sometimes Rowe will get a letter criticizing him, and this time when Craig P., wrote in saying Rowe’s ‘constant harping on ‘work-ethic’ is growing tiresome’, Rowe had the perfect response.

He pointed out that as he crosses the country he has met many people that while they are hard workers most people would prefer not to work, and that today’s generation tend to not understand what it means to put in a full days work.

Hoover Dam: A Symbol of Simple Strength

Friday, June 26th, 2015

During the Great Depression, in the 1930’s, when there were no jobs available, the Hoover Dam was in the beginning stages of being built, signifying the will and determination of a nation to survive economic turmoil. This solid concrete structure, blocking the walls between the Black Canyon along the Colorado River, would prove to be the highest, most costly water project and power plant at that time, and more then ninety-six workers would die building this symbol of national strength.

To say the building of the Hoover Dam was a dangerous undertaking would be a a severe understatement, as men from all over American, including former sailors, circus acrobats and Native Americans, risked their lives scaling the rock, and using dynamite to to blow away lose rocks before the work could begin. They worked twenty-four hours a day, breaking the time up into three shifts, and were paid $1.60 a day which was considered a very good wage at the time. To read the full story of the building of the Hoover Dam, and to learn about key players in this massive project, click here…

Building Safety Month Week One: Don’t Get Burned – Build To Code

Thursday, June 25th, 2015

The need for safe and sustainable homes and structures where we live, work, and play are important factors for every community. May is Building Safety Month, and this public awareness campaign is presented by the International Code Council and it’s members of building professionals worldwide. This year’s theme is Resilient Communities Start with Building Codes, and each week a different topic is covered. For week one it was “Don’t Get Burned – Build To Code”, which focuses on smoke and carbon monoxide alarms, sprinklers, and passive fire-rated construction practices, as well as creating escape planes and avoiding careless smoking habits.

Building codes are based on science, technical knowledge and past experiences that provide buildings protection from man-made and natural disasters, they guard public health, and they reduce property losses. Building codes have been protecting communities for literally thousands of years with the earliest code dating back to circa 2200 B.C.
