Reflection Spectral Analysis of Fiber Bragg Gratings

Reflection Spectral Analysis of Fiber Bragg Gratings

We present a detailed experimental study of Bragg grating reflection spectra around the wavelength of λB = 1560 nm for different tilt angles set between the fiber and the phase mask. An optical Bragg grating is a transparent device with a periodic variation of the refractive index, so that a large reflectance (less precisely: reflectivity) may be reached in some wavelength range (bandwidth) around a certain wavelength which fulfills the Bragg condition where λ is the vacuum.

Analysis of Relay Protection Failure to Trip

Analysis of Relay Protection Failure to Trip

This paper focuses on developing a fault tracking model and process for the RPS-CB (relay protection system and corresponding CB), aiming to investigate the relationship between system faults and the incorrect operation of the PR and CB. Abstract A distance relay, which is widely used for pro-tecting a power transmission line as the primary as well as remote backup device, may be affected by the power dis-turbances such as power swings and post-faults. To improve protection quality, it is useful to identify and record perfo of electromechanical, solid-state, and digital relays. Specific system quality measurements include relay misoperations; relay failures to operate; relay delayed.

Analysis of Distribution Box Switch Faults

Analysis of Distribution Box Switch Faults

This study presents a mathematical approach to analyze and detect major faults in the distribution system using advanced fault location techniques, power flow analysis, and statistical methods. Low-voltage switch belongs to the high-frequency electrical appliances in low-voltage electrical appliances. An arc is created by ionization of a gas (normally air) by means of an electric discharge between electrodes of different potential or phase angle, or between an electrode and earth. Diagnose the fault in a low voltage distribution box by checking for overheating, loose connections, and using voltage testers for safe troubleshooting. Sometimes equipment will fail spontaneously for reasons such as chronological age, thermal age, state of chemical decomposition, state of contamination, and state of mechanical wear. The following paragraphs in this technical article present the most common modes of failure for equipment that is.
