BRAGG Asset Monitoring

What are Bragg Networks?

Lumiker: Bragg

Bragg Networks are sensors placed on optical fiber to measure deformation, vibration, temperature, inclination and other parameters.

A Bragg network is a periodic or aperiodic disturbance of the effective refractive index in the core of an optical fiber.

Normally, the disturbance is approximately periodic over a certain length of, for example, a few millimetres or centimetres. The period is in the range of hundreds of nanometres.

AEROSPACE STRUCTURAL MONITORING WIND ENERGY MONITORING SOLUTIONS LUMIKER TEMPERATURE SOLUTIONS (LTS)

Lumiker is developing solutions to monitor structural health of Aircraft Major Components, mostly for FTI applications.

Lumiker´s technologies allow to adapt the interrogating equipment to redundant systems, to interrogate semi-distributed sensor arrays, in a scalable way, where the client can decide to monitor single variables at several locations, or move to a more complex system with multiple variables and thousands of location.

We think that FBG sensors are the best optic solution to this application, since a Raleigh based system has a very slow real-time data process and is very difficult to calibrate to precise testing data collection, and a Brillouin system is far away the target cost for a testing application.

Lumiker is developing solutions to monitor the operational conditions of Wind Parks, their assets and specific wind turbine components.

Using the Faraday Effect we can effectively measure currents in module and angle in all the electrical equipment associated to the Park ( have a look at our CAMOS Solutions here), and using Bragg Gratings we can effectively measure the mechanical behaviour of any component either at critical locations or in a semi-distributed way.

Using specifically designed interrogation units, with redundancy, diminishes the use of fibre with our multiplex systems. Our serial sensor arrays leverage systems that can monitor Wind Blade Aeroelastic and Torsional States to improve their health monitoring and correctly command the pitch control system to improve the WTG efficiency.

Our data collection is precise, continuous, not affected by EMI, has the best real-time and Cloud Connectors (4G, 5G) at the best cost.

As part of our Bragg monitoring solutions, Lumiker has developed and integrated in several assets our Temperature Monitoring solutions.

Ideal for HV Cable Monitoring and other Thermo Critical Assets (Turbines, Heaters, Pumps…) this system allows to measure critical points with a very high precision (0,5ºC) in a real-time basis.

Lumiker also offers to calibrate, with the collected data, any thermal dynamic rating model (Analytical, or Finite Element) and to aid with the establishment of predictive strategies, on the remaining useful life (RUL), or to enhance future designs of the asset.
