ITU professor receives Patent for Electrical Voltage Measurement Device

 

ITU Interim Provost, Dr. Karl Wang, has received a patent for a piece of technology contained in ITU’s proprietary Smart Meter device. The device allows for a transformer-less system for sensing voltage and current shifts in power output. Dr. Wang invented the device with the help of ITU student researchers over the past two years.

Granted earlier this month, the device was fast-tracked last year for patent approval by the United States Patent and Trademark Office (USPTO). The patent will grant ITU, and Dr. Wang, sole ownership of the invention.

An Idea Born Out of the Classroom

The basic concept for the device came from Dr. Wang’s work in education. While teaching his Embedded Systems course in 2013, Dr. Wang asked his students to do a final project on energy management. One of the key points of of this project was the inefficiency of modern day electrical transformers.

“We were thinking about all the problems about using transformers for voltage and current sensing, and at the time I was thinking there might be a better way,” says Dr. Wang.

An Invention for Measuring Power

Along with his students, Dr. Wang did end up finding a better way. He was able to pinpoint a key inefficiency in the way electrical transformers were measuring electrical output. Using optically coupled isolators, Dr. Wang found a solution to the problems of modern day transformers.

Electrical transformers are used to track the power output for buildings. Dr. Wang discovered that the transformers currently in use have two key drawbacks: they’re too big, and are sensitive to magnetic waves. The Smart Meter improves upon these two weakness by being smaller and utilizing a design that cannot be tampered with via magnetics.

According to Dr. Wang: “If you use a normal transformer, you can saturate the core of the transformer, and you no longer sense the correct voltage and current. People will sometimes do this to defeat the normal electrical voltage measurement, and in a way, steal power from companies like Pacific Gas and Electricity (PG&E). The Smart Meter uses an electronic part called an optical coupler and isolator, meaning it’s not sensitive to external magnet fields. So it’s tamper proof. “
