Undersea power cable contract awarded

  ABB has won an order worth around US$11-million from the Swedish utility Svenska kraftnät to design, manufacture, and supply a submarine cable system under the bay of Edsviken in northern Stockholm. The link is part of the larger grid project Stockholms Ström, which will provide an entirely new structure for the electrical grid in […]

Energy company releases results

ABB has announced its annual results for 2014 at a media event hosted in Johannesburg. The company’s revenue has decreased from R5,9-billion in 2013 to R4,8-billion in 2014. ABB managing director Leon Viljoen explained that some of the 2013 revenue came from the 150 MW PV project the company was involved in while R3,5-billion worth […]

Passive and active ARC fault protection in LV switchgear

The traditional methods of passive arc fault protection and the latest active protection options and applications available to industry. Having to wear a “moon suit” against arc flashing when entering LV switch rooms is new to South Africa and many companies who have never experienced arc flash incidents are awaiting developments in the occupational health […]

ABB releases results

  ABB Southern Africa MD Leon Viljoen said the power and automation company has continued to show growth over the past year in its base business despite a subdued local and global economic environment. Revenue, however, was down from R5,9-billion in 2013 to R4,9-billion last year. Speaking at the company’s annual results briefing, Viljoen said […]

Power and automation company bullish about the future

Optimising production planning in cement plants

  ABB has launched Knowledge Manager Production Scheduler, a new software solution to manage and optimise production scheduling in cement plants. It provides customers with optimal planning functionalities based on real-time information, considering production goals, business constraints as well as volatile energy tariffs to increase the overall process efficiency. This application allows the user to […]

HVDC system provides additional power to neighbours

  ABB has commissioned a high-voltage direct current (HVDC) link between Norway and Denmark to increase availability of renewable hydroelectric and wind power in the region’s electricity grid. At 500 kV, the Skagerrak 4 link sets a new record in transmission voltage using Voltage Source Converters (VSC). The converters rely on semiconductors to convert electricity […]

Trends from the automation capital

  The buzzwords at this year’s SPS IPC Drives Exhibition in Germany were “energy” and “data”. Economic pressures, environmental consciousness and regulations have influenced product and service designs, and shifted the focus to technology optimisation. Automation trade fairs and conferences are good indicators of shifting trends in the market, and the SPS IPC Drives Exhibition […]

Understanding boundary conditions for reliable electrical simulations

  Understanding partial differential equations (PDEs), which form the basic language with which physicists describe many natural phenomena, such as electric and magnetic fields, acoustics, fluid flow, and heat conduction, is useful in electrical simulations. The PDEs that describe the physics inside a spatial domain of interest – so-called bulk equations – are the key […]
