2nd Quarter 2016Electrical switching & drive systems & components
ABB is supplying a special medium voltage switch-fuse combination switchgear for power protection and isolation in unit substations for one of the country’s largest wind power projects. The Longyuan Mulilo De Aar 1 and 2 wind projects in the Northern Cape will have installed capacities of 100 and 139 MW respectively. ABB’s NALFWind 36 kV switch-fuse combination units will be incorporated into 163 unit substations as part of a R15 million order from Adenco Construction, the EPC contractor for the R5 billion wind project.
The switch-fuse combination units are specially designed for use in wind electricity distribution environments where HRC fuses are required to handle high levels of fault energies to provide protection and isolation on the windfarm electricity network. It is the first time that the NALFWind 36 kV switch-fuse combination units will be used in a unit substation on an onshore wind farm. The fuses used for the NALFWind are a new design based on the fast acting ABB CEF-S, which secures and protects against faults in low-voltage switchgear. The CEF-S fuses are specially designed to achieve breaking current value within 100 milliseconds.
“This is an advanced technology breakthrough which will maximise cost effectiveness and safety,” says Mike de Swardt, ABB regional manager, Western Cape. “It is far more cost-effective than traditional ring main unit solutions for compact substation applications.” The project commenced in the third quarter of 2015 and is expected to be operational by the last quarter of 2017.
Precise detection of complex rotational movements Beckhoff Automation
Electrical switching & drive systems & components
The EP3751-0260 EtherCAT Box module by Beckhoff connects an acceleration sensor with an inertial measurement unit - a gyroscope. This provides accurate detection of acceleration and rotational motion in addition to shock, vibration and tilt measurement, both as preprocessed values and as raw sensor data.

In the machine manufacturing industry, more drive systems are being converted from servo-hydraulic throttle to electrohydrostatic actuation systems. The four-quadrant capability of the electrohydrostatic pump unit and servo drive used in this technology, in combination with the new Moog energy management system, allows regenerative power flows generated during braking or pressure relief to be stored and reused.
