A wireless system for measuring current in power electronics and transmission lines is being developed at Yaroslav-the-Wise Novgorod State University (NovSU). This was announced by Ivan Markov, a research engineer at the NovSU's Laboratory of Micro- and Nanotechnology.
Modern trends in the field of measuring equipment require the development of new non-contact devices that will be able to measure large electrical quantities with low error. By using a new physical principle, the magnetoelectric effect, these devices will be able to measure high direct and alternating currents up to 10 kA, and the wireless system will transmit this data to the operator at any distance non-stop.
Currently, large currents are measured using shunts or transformers. They are not capable of making accurate measurements. The new development solves this problem. The installation also has no analogues in the world.
By using cheap materials and technological processes in the manufacture of sensors, our system can become very competitive and replace expensive measuring transformers. Due to the low cost, the final product will be able to interest manufacturers of measuring and electrical protection equipment, as well as enterprises of the electronic and energy industries.
Specialists are currently testing special sensors. In the future, they will be integrated into a wireless system.
