From the World of Testing
Many in our industry predict the future will bring greater blending of technology and hybridization. But what does hybridization mean in power systems? And what are its implications for testing? To answer, it is important to recognize that the key enablers of transformational change in electric power systems are digitalization, information technology and...
High voltage direct current (HVDC) has rapidly become one of the ‘hot’ topics in transmission. Since the first HVDC connections date back to the 1950s, it can hardly be called ‘new’. But recent market requirements have resurrected the technology and... Read More
In the future, advanced power electronics will enhance and even replace traditional components due to their superior controllability. In the process, they offer the potential to ‘disrupt’ the type of electric power system we know today. Three key issues... Read More
Failure of a large power transformer is probably the worst nightmare scenario faced by a transmission system operator. Repercussions can be enormous. First is the initial outage, which in major urban centres can cost tens of millions per hour. And that does... Read More
Last year, this column discussed how new technologies allow the T&D industry to combine economic opportunities with environmental goals. One example has been the search for ‘green’ alternatives toSF6 for gas-insulated switchgear and circuit breakers.... Read More
Utilities are the public face of the transmission and distribution (T&D) industry. They maintain local infrastructure and are tasked with ensuring reliability. It is also their names customers see on monthly bills. Therefore, if something goes wrong with... Read More
The T&D grids of tomorrow will have to be much more complex and interactive than the ones we know today. For example, the rise of renewables and demand-side response in power systems is leading to a new age of real-time controllability. Renewables will... Read More
