![]() ![]() The size is a major advantage – a conventional 300kV CT stands 4m tall and weights 1200kg, compared with the Smart Digital Optics FOCS which measures 0.5m x 0.2m x 0.25m and weighs 10kg. “Our technology is smaller, lighter, more accurate, has a wider dynamic range and cannot lead to explosive breakdown, unlike its conventional counterpart,” he said. Smart Digital Optics director Dr Ian Bassett said the FOCS measured the magnetic field produced by an electrical current, through the effect of that magnetic field on light guided by a glass fibre passing around the current. It can be picked up in one hand, and its developers say it is more accurate, safer, more durable and leaves a much smaller environmental footprint than its conventional equivalent. Enter Smart Digital Optics’ fibre optic current sensor (known as FOCS). ![]() Conventional current transformers (also known as CTs or instrument transformers) have traditionally been complicated and cumbersome – often they are so large, a crane is needed for installation. ![]() Smart Digital Optics Australia n/a Scientists and researchers at Sydney-based company Smart Digital Optics have made a giant leap forward in the way electrical currents can be measured. Packair compressors are also scalable and can be coupled together to produce higher volume output, while providing backup air on-demand VentureRadar Research / Company Website Packair’s compressor is also significantly smaller and lighter than common portable commercial compressors being offered on the market today, and can be powered by either grid AC or DC batteries. The Packair Compressor does not require a heavy or bulky storage tank, and it out performs conventional compressors by reaching and maintaining a working pressure in excess of 90 PSI within 2 seconds. ![]()
