Grounded Grid

How is a 3-phase power grid grounded?

Obviously a 3-phase (or other mult-phase) power system needs to be grounded, but I am curious as to how this is done? Where are the ground wire(s) attached and where do they end up? Does a ground wire go to the ground actually or somewhere else? It seems like if it went to the ground it could be dangerous… I don’t know much about electrical power or high voltage, but I think it is interesting. So, if you can answer this please do! -Thanks!

Ultimately the ground is literally the ground. The earth is a good conductor and is so absolutely massive that there is no problem with grounding this way – it’s not dangerous.

Of course, if a power line with 60000 volts is laying on the ground it’s dangerous, because the ground near it will be live to some extent.

But, as an example, here in Australia where the mains voltage in homes is 240V, 3-phase power is 430V. It is a lot, but not when it comes to being put into the ground.

We've all heard a bit of talk, speculation, argument and the proposal for a solution to the energy problems of our country. Moreover desperate our dependence on foreign oil, U.S. also contributes a large portion of greenhouse gases that pollute our planet, so clearly a solution is eminent. The beacon of hope has been placed on the shoulders of a network of the future 'smart' – an energy efficient and eco-friendly network that can feed our country and perhaps save our economy.

A lot of critics have argued that the viability of such a network of high-energy high technology-a network that can seamlessly integrate renewable energy sources like solar and wind power can be connected to the main urban centers of long distance and can be regulated to depending on where the energy should be assigned. "Smart Meters" should be carried out in houses, apartments and resorts business to provide constant feedback to the network.

Despite the reaction to the initiative, President Obama's administration has continued with the stimulus money allocated towards the construction of the intelligent network. One of the first historic steps taken today proposes Miami head of the initiative with a proposed $ 200 million to create an intelligent network of Florida. The intelligent network, 'Energy Smart Miami, "will be built by Cisco Systems network powers and General Electric, among several other companies that want to put their feet wet with the new green wave of smart technologies.

Diaz, Miami Mayor described the project (energysmartmiami.com): "The Smart Energy Initiative of Miami is an investment in the future of our city, our residents and our neighborhoods, and is an important step toward creating green jobs of the future and building a clean energy economy. This initiative meets the goal of an Obama administration to invest in alternative and renewable energy, ending our addiction to foreign oil, compared the global climate crisis and create millions of new green jobs. I look forward to working with our partners in the private sector to create a model to the stimulus economic and opening action immediately. "

The central theme of "Intelligent Energy in Miami will be the installation of over 1 million smart meters for homes and businesses in Miami, which will provide immediate feedback on energy use Flordia Power and Light Company. These meters also enable the citizens of Miami and business owners to better track and manage their energy use by that provide updated statistics.

Cisco Systems, the worldwide leader in networking hardware and technology, will contribute by creating the infrastructure and network of these systems. This is business, data task to create energy management and controls for customers, as well as to implement the project safety and communications technology. In other words, Cisco hardware play an integral role in providing the column backbone of the entire network.

John Chambers, Cisco CEO, commented on the role of corporations in creating the network: "A power infrastructure intelligent leadership can accelerate the U.S., create jobs, help increase our living standards and promote sustainable growth. Cisco believes that as the U.S. build an intelligent network, secure energy for the 21st century, network technology will provide a platform and public-private partnerships will be critical to success. We are proud to be part of this important effort in Miami. "

If the city of Miami, Cisco and others can be successful in the first of the intelligent networks, establishing the President for the remainder of the country. U.S. Takes closer to the gigantic task of transition in an enlightened age of conservation energy and environmental sustainability.
