Profotec: Fiber optic sensor for ultra-high current measurement

2023: Obtaining a patent

The resident of the special economic zone (SEZ) "Technopolice Moscow" received a patent for a fiber-optic sensor, which is designed to measure ultra-high currents. Profotec has developed a device for the project of an experimental thermonuclear reactor - the latest generation of power plants capable of generating endless and clean energy. The device has passed a number of tests and confirmed the declared characteristics. This was announced on April 27, 2023 by the head of the Department of Investment and Industrial Policy of Moscow, which is part of the Complex of Economic Policy and Property and Land Relations of the capital, Vladislav Ovchinsky.

The development of Profotec belongs to the technologies of the future - controlled fusion, which can provide large volumes of environmentally friendly and safe energy. Russia was the first to develop fusion reactor technology and build an experimental facility, the so-called tokamak. Work in this direction is still underway, so the development of a resident of the SEZ "Technopolice Moscow" is of great practical importance, - said Vladislav Ovchinsky.

The company is engaged in the development, production and implementation of equipment based on its own innovative technologies from the field of photonics. The company's products are used in the construction of solutions for intelligent power and energy-intensive industries.

The presented technical solution will provide the possibility of measuring ultra-high currents - from hundreds of kiloamperes to tens of megaamperes, which are observed during the operation of a thermonuclear reactor. The products of manufacturers of the capital's SEZ are in high demand on the market, "said Gennady Degtev, General Director of the Technopolice Moscow SEZ.

The main element of a thermonuclear reactor such as a tokamak is a system for long-term retention of hot plasma in a toroidal chamber due to a magnetic field. Depending on the power, the installation is able to create a current of 1 to 17 megamperes in the plasma, while the plasma itself warms up to 150 million degrees Celsius, which is 10 times more than in the core of the Sun.

The peculiarity of the development is manifested not only in the high accuracy and stability of measurements of constant and pulse currents, arising in the chamber of the thermonuclear reactor, but also in the possibility of scaling the solution in terms of the ranges of measured values ​ ​ and the possibility of porting the invention into measurement and protection systems for power equipment of traditional power - powerful generators and transformers of hydroelectric power plants and nuclear power plants, - summed up the technical director of the company Maxim Yanin.
