Optic fiber transducer to monitor vibrations in transmission line cables

Engineering, Machines and equipment, Public Domain, Utilities

Resistance and precision

The transducer is resistant to adverse conditions such as high temperatures, humidity and electromagnetic fields, as well as environmental conditions such as rain, wind and dust.

Easy installation

The transducer is easy to install and can be attached directly to the transmission line cable.

Reducing costs

The transducer is cheaper and easier to install than traditional monitoring methods.

Security

The transducer does not require physical access to the cables, which reduces the risk of accidents.

The problem-solution approach

Transmission line cables are subjected to mechanical vibrations caused by various factors, such as wind, rain, ice and earthquakes. These vibrations can cause damage to the cables, compromising the safety and reliability of the power grid.

What is it?

This optic fiber transducer is a device that uses light to measure mechanical vibrations in electrical cables. It consists of a flexible beam, an optical fiber and a Bragg grating sensor.

How it works

When the beam is subjected to vibrations, it deforms. This deformation is transmitted to the optical fiber, which changes the wavelength of the light it transmits. The Bragg grating sensor detects this change and converts it into an electrical signal.
