The Case for Reliable Sensors

There are plenty of examples that demonstrate how vital it is that sensors always function as intended – even under abnormal situations. Tragic events such as the recent crash of an airliner in Indonesia due to a false speedometer reading or the Turkish... Read More

Simulation Versus Laboratory Testing

The transmission and distribution sector faces a constant challenge to deliver reliable as well as affordable electrical power. Hence, it is always looking how best to improve on both. Standards-based certification of equipment has traditionally been viewed... Read More

Dealing with Hybrid Grids

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... Read More

Advanced Power Electronics Will Rule Future Power Systems (Part 1)

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

Testing Can Reduce Transformer Failures

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

Replacing SF6 is Switching How We Think of Transmission

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

Equipment Certification Vital to Utility Image

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
