WHY YOU NEED TO INVEST IN THE POWER CLOUD 1 Around 130 years ago a technical revolution took place that was to be a vital step in the development of modern society History is marked by a series of great inventions that have swept across society, acting as stepping stones in the emergence of the modern world. Most people would agree that fire, the wheel, modern transportation and communication systems, culminating with the Internet all have a place on this list. Maybe less obvious but equally pivotal is the large-scale transmission and delivery of electrical energy over long distances. This breakthrough that would not have been possible without the transformer. In the first of three posts I will take a brief tour of the history behind the transformer. A look back in time Around 130 years ago a technical revolution took place that was to be a vital step in the development of modern society. That revolution was the commercial generation, transmission and usage of electrical energy. Nobody today can imagine a world without electricity. However, I will start by taking you back to the early days when pioneers like Thomas Edison and George Westinghouse – and their ideas were competing for the transmission system of the future: Should it be DC or should it be AC? Very early electrical installations were local: The sites of generation and consumption were at most a handful of kilometers apart: Direct connections from the steam or hydro generators to the consumers were in the range of hundreds of volts. In the early 1880s, for example, the “Edison Illuminating Company” supplied 59 customers in Lower Manhattan with electricity at 110 V DC. But the energy demand of the fast growing cities and industrial centers called for an increase in power transmission capability.
