Resistor liquid cooling boosts 3.3kV medium voltage loads
In motor-driven applications like cranes, lifts, hoists and conveyors, air cooled resistors are common, but in medium-voltage, high-power applications liquid cooling wins out. A medium voltage drive running off a 3.3kV supply to turn a 500kW motor will put a severe heating load on the application’s power transistors – hence the need for water cooling, as David Atkins, projects director at Cressall Resistors explains.

SCADA in the next 30 years
Industrial SCADA is undergoing a step change right now, with the move from proprietary code to next generation technologies such as compatibility with SQL Databases and Cloud Computing .NET, OPC UA and HTML5. This is part of moving towards a more connected world and a natural progression oriented towards technologies of the immediate future. Paul Hurst, MD independent UK SCADA and HMI vendor Products4Automation (P4A), talks about the future of SCADA.

The braking resistors that will not break
One of the most popular works of Renaissance sculpture is Michelangelo’s David, a piece that has become synonymous with human strength and beauty. Despite its seemingly perfect proportions, a basic design flaw of the statue has recently been brought to light. Recurring micro-fractures in the ankles might cause the statue to collapse under its own weight. Here, David Atkins, projects director at Cressall Resistors, explains why design is essential not only in art, but also in industry, especially when designing equipment such as power resistors for demanding environments like oil and gas.

Getting things right first time with PLM and BOM
The creation of a Bill of Materials (BOM) is a fundamental part of product development. However, manufacturers are often unsure at what stage of the product development the BOM comes in. Best practice dictates that the BOM needs to travel fluently through the different development stages, evolving and changing as products are designed, built and eventually, circulated. Here, Geoff Turner, product lifecycle management (PLM) consultant at Design Rule, examines the value of getting the BOM right in the early stages of a project.

Gears for packaging machines
Most people probably open tens of packaged goods a day without even realising it. Opening jars, cereal packets and sandwich boxes are all part of our daily routine, but we don’t tend to notice the packaging until something goes wrong. When milk cartons burst, drinks spill in your bag or crisps go stale when they’re not properly sealed, it can be infuriating. Here, Graham Mackrell, managing director of Harmonic Drive UK looks at how gears for packaging machines keep your goods fresh.
