Co-generation using plant furnace gas
It is estimated that SA mineral smelters and chemical processes have the potential to generate more than 2000 MW of electricity from waste gases. In addition to reducing grid energy consumption, projects of this type qualify for clean development mechanism (CDM) funding... (more) |
New experience in transformer fault diagnosis
by Michael Krüger, Omicron
With advancing age of power transformers, a regular check of the operative condition becomes more and more important. Dissolved gas analysis (DGA) is a proven and meaningful method that allows a fault to be located as soon as possible if increased proportions of hydrogen and hydrocarbon gases are found in the oil...

Automation of transformer oil testing
by Tom Dalton, Martec
Oil sampling is a process and not just a result. There are many steps that can introduce errors. By using online monitoring most of the errors can be eliminated. Automation of the diagnosis of the oil condition can also provide improved results... (more) |
Get substation automation in sync
by Justin Wu and Bruce Chen, Moxa
