What you need to know right now about smart grid sensors


By: SGN Staff

Quick Take: A few weeks back I warned that we are about to see a changing of the guard in smart grid sensors. The market is undergoing radical change as older devices are replaced by next-generation technologies. Because it's important to prepare, I thought you might value a past presentation by Dr. William Kao of California Polytechnic Institute. I've summarized some key points below, or download the slides here. - By Jesse Berst


Kao believes sensor networks will be a key enabler to provide real-time information for the smart grid. The measurements needed for smart grid fall into six categories.

·         Voltage

·         Current

·         Temperature

·         Moisture

·         Continuity

·         Phase measurements


Important smart grid applications include advanced metering infrastructure (AMI), smart voltage sensors, remote capacitor control, outage detection, transformer monitoring, high voltage line temperature, weather conditions, distributed generation and load balancing, energy storage and dispatch.


Key applications in adjacent sectors include smart buildings, home energy management systems, intelligent city transportation systems and urban precision agriculture.


A major gating factor may be the need for data fusion - gathering, filtering, aggregating and analyzing data from multiple sources. The market also suffers from a lack of interoperability.
