The importance of computer simulation as a tool is growing in all areas of engineering. In industrial control, simulation is an Information from ABB effective way to minimise effort for test preparation, provide imitations of comprehensive systems under test, and to enable systems to be tested dynamically on the shop floor. This allows a reduction in both changes to device applications during commissioning and, ultimately, plant downtime… (more)
For many decades, permanent magnet technology has been used in smaller scale applications where its favorable weight-to-performance ratio is an advantage. Its use in bigger electrical machines, however, has not been that common. This, however, is changing. The increasing demand for new solutions for wind power generators and special motors for industries such as pulp and paper, marine, and traction has created new markets for electrical machines… (more)
DC motors have, in the past, been regarded as “extinct”, but thyristor converters have come to the rescue. Many of the motor’s key attributes were previously considered mutually exclusive; it was not possible to combine them in the same machine. Thanks to the motor range known as DMI, customers have been taking advantage of high power, a wide speed range, high torque, small dimensions, and high overload capacity or low moment of inertia simultaneously for some years… (more)
Operator effectiveness is a fundamental element for sustaining the economic value of process control and management. It can be improved by empowering operators through improved situational awareness and better handling of abnormal conditions. Operators can then make better decisions and so improve process safety and process uptime… (more)
Earthquakes have the potential to cause extensive damage to infrastructure. Making power products earthquake-proof is no easy task… (more)
Safety is paramount to manufacturing and should be every company’s highest priority. This objective may sometimes appear to be in conflict with the goal to be as productive as possible… (more)
From the environmentally-sensitive landscape to the main office block on the ABB campus in Longmeadow, Modderfontein in Gauteng, it is apparent that ABB and its people walk the green talk – they are 101% environment-friendly… (more)
In large industrial plants that often contain several thousand motors to provide the necessary motion, any unplanned or sudden motor stops can lead to faults in the process sequence, which can be very cost-intensive. For this reason, reliable management and protection of these motors is of vital importance for ensuring a controlled production sequence… (more)
A circuit breaker is one of the most important and essential safety mechanisms in electrical systems. Many different classifications of breakers can be made, based on voltage class, construction and interrupting type, and structural features… (more)
Global process industry losses are estimated at around $20-billion annually, corresponding to 5% of total production. Four-fifths of these losses are preventable and 40% thereof are primarily due to operator errors… (more)
Strategic thinking when facing a tough challenge requires recognising how to make optimal use of all available assets. A chess player, for example, who chooses to exclude some of his chessmen from his strategy, is inherently disadvantaging himself. This is no different in manufacturing processes… (more)
Innovative and intuitive technology for building and room control solutions can be adapted to the user’s needs and also help to increase energy efficiency… (more)
ABB’s global consulting business was able to help a global steel producer to find circa R150-million in annual energy savings at one of its integrated steel mills, through the application of a structured industrial energy efficiency program… (more)

The PdMSA 2010 Conference and exhibition, hosted by ABB South Africa and Martec, to be held on 1 and 2 September at ABB’s premises in Johannesburg, will offer interactive sessions delivered by local and international industry experts sharing the vision for asset health. The sessions will offer insight on how to use predictive maintenance and condition monitoring to increase uptime and plant availability, without increasing cost… ( more)
A constant supply of natural gas to power stations and marketing networks is maintained through integrated production, transportation and distribution. The authors discuss how SCADA systems improve liquefied natural gas operations and management of a plant in China… (more)
“The results of ABB South Africa for 2009 were similar to those of the ABB group worldwide”. said Carlos Poñe, CEO of ABB South Africa, speaking at a media briefing on thursday. “We performed well considering the tough economic conditions; our customers continued to invest in world class technology to urgently upgrade ageing electricity infrastructure. Industrial customers invested in solutions to increase energy efficiency ahead of the new electricity price regime.”… (more)
The fact that South Africa has a large pool of unemployed labour is often used in discussions on whether robotics has a place in South African industry. It is argued that better use should be made of the available labour resources by providing sustained training programmes… (more)
Small, fast and cheap PLC solutions usually offer few engineering options and often do not provide convenient visualisation. In contrast, distributed control systems integrate a host of components such as controls, engineering tools, human machine interfaces and numerous peripheral devices and tools… (more)
