The Number of Patent Applications in Failure-Detecting Autonomous Diagnostic Technology..
7 Aug 2016 The Electronic Newspaper
It was reported that there had been a continuous rise in the development of technology that enables early detection and autonomous diagnosis of failures in power utilities in the midst of growing concerns for blackout (a massive power outage due to temporary surge of electricity demands.

Korean Intellectual Property Office (KIPO) announced on 7th that the number of patent applications related to autonomous diagnostic system for power utilities had recorded a continued increase with a mere of 29 from 2000 to 2002, 51 from 2003 to 2005, 80 from 2006 to 2008, 174 from 2009 to 2011, and 277 from 2012 to 2014.

The increase can be explained by the advantages of autonomous diagnostic technology in power utilities, which enable monitoring and managing the power utilities in real time in preparation for emergencies, such as a massive power outage, in the midst of growing power usage.

When analyzed by sectors, power utility diagnostic technology related to incoming panels and switchboards distributing electricity to customers or performing voltage transformation, topped the list of power utility patent applications at 51%, followed by diagnostic technology in electric track and electrical connection point at 28%, and battery diagnostic technology at 2%.

The patent applications in power utility diagnostic technology related to incoming panels and switchboards, which had been filed the most, have conventionally relied on a method of directly measuring the voltage and electric current of power utilities and making a diagnosis based on that result. However, there has been an increase in the number of patent applications filed for the latest diagnostic technology using sensors.

An ultrasonic sensor for measuring ultrasonic waves makes up the most at 47% in the total number of patent applications filed for sensors that enable diagnosis of failures in incoming panels and switchboards, followed by an infrared sensor for detecting heat at 26% and an ultraviolet-ray sensor for detecting light from sparks at 21%.

The patent applications in incoming panel and switchboard-related power utility diagnostic technology using an ultrasonic sensor have been filed the most by small and medium-sized companies at 32%, followed by universities and research institutes at 32%, large conglomerates at 24%, and individuals at 12%.
