Non-destructive coupler characterisation technique

, 2002
A novel nondestructive technique for characterising couplers by means of a local perturbation is described. The method is studied theoretically and verified experimentally by characterising different types of fused fiber-couplers.

High temperature performance of an optical microfibre coupler and its potential use as a sensor [PDF]

, 2012
The dependence of the transmission spectrum of an optical microfibre coupler at high temperatures is investigated experimentally. Results show a temperature sensitivity up to 36.59 pm/°C at a taper waist outer diameter of 2.5 µm; such a temperature ...

Analysis and Comparison of Sensors for Measurements of Partial Discharges in Hydrogenerator Stator Windings

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In order to measure electrical signals produced by partial discharges in hydrogenerators stator windings, capacitive couplers are regularly used. They are electrically connected to the windings and therefore, require undesired insulation intrusion.
