Power Quality Audit

Electricity is undoubtedly one of the cornerstones of modern society. Hence power quality monitoring becomes all the more relevant. However, without stringent codes and protocols in place to analyze power and regulate its use, it can yield dangerous consequences. An uninterrupted power supply is essential and a relatively difficult feat to achieve at many types of facilities ranging from government and commercial buildings to healthcare centers, data centers, and manufacturing plants. When it comes to reliability of power in large buildings, foresight is a lot better than hindsight. Compromised power quality will not only reduce productivity but also cause severe damage...

Expert Power Quality Monitoring Platform: Propelling the Health Care Sector Forward in Times of COVID-19 and Coronavirus Crisis. The need for a power analyzer in hospitals cannot be undermined. Against a sizeable digital backdrop and as our world advances into the digital age, our physical structures are undoubtedly becoming increasingly redundant. One overarching example is hospitals. With technological strides and advances, aging hospitals and healthcare facilities are creating a massive loophole in facilities; they can unflinchingly support without expensive electrical retrofits and with existing infrastructure. In the field of healthcare, digital devices that are frequently used by nurses and doctors...

New technology allows processors to monitor electrical power in their plant and diagnose hiccups so they can more intelligently find a solution. For D.J. Parry, it was a real head-scratcher. The operations manager of stretch-film processor Goodwrappers Inc. was first made aware of some odd goings-on in his Baltimore plant in February. His third-shift team told him of output losses resulting from his two extrusion lines slowing down, seemingly out of nowhere. Moreover, his water-circulation units, which are used to cool his extruders, were conking out altogether.  Had gremlins been running amok in Parry’s plant in the wee hours of...

Internet of Things (IoT) has been on the hotbed of activity last several years. While till about 2015, IoT was at its peak of ‘Gartner Hype Cycle’, the euphoria has died down considerably with many others like AI and blockchain taking its slot at the top. IoT is on a downward path of the Hype cycle now but as the authors have articulated in previous posts, articles and interviews, IoT, especially Industrial IoT would see a steady but slow progress over a decade. IT deployment and automation took decades as well and adoption did not happen overnight. While the IoT...

Fig. 1: Typical compressor installation in factory 1. Introduction: Compressor failure is also a common factory problem and it costs a huge loss of production if it fails suddenly. More importantly, in large factory compressors are connected in cascaded way so one single failure can affect other compressor. We can think it as an electromechanical machine/device where one electrical machine(motor) and mechanical pump are combined together. Due to poor power quality supply to the compressor, it can fail. 2. Common causes of compressor failure:     a. Presence of VFD/DC drive nearby:     b. High current imbalance in compressor input...
