Undoubtedly investment costs for electrical drives are minor when compared to the overall investment in a system or plant. But it is the energy consumption of the selected drive technology that has a decisive influence on the follow-up costs.
If users compare all costs incurred during the life cycle of a system, it will be seen that energy costs of systems that have not been optimised with respect to their energy consumption can constitute up to 90% of the follow-up costs. Thus, optimising the energy efficiency of each individual component and combining the drive technology to match the specific application will achieve a significant economic benefit.
SEW Eurodrive has added a user friendly energy-saving calculator to its website. The calculator needs only a few details on the application and in return it will give users an estimated energy saving per annum as well as an indication of the amortisation period.

Maintenance, Test & Measurement, Calibration
Cathodic protection keeps buried and submerged pipelines safe from corrosion, but verifying it traditionally means costly, hazardous manual site visits. Omniflex explains how a retrofit module brings remote monitoring to ageing transformer rectifiers without replacing functional infrastructure.

Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.

Maintenance, Test & Measurement, Calibration
WearCheck ARC division manager, Annemie Willer argues that the greatest threat to effective maintenance is no longer a lack of technology, but the gradual replacement of technical judgement by CMMS compliance, leaving no one owning the machine.
