Power quality disturbances in distribution networks caused by the influence of nearby power lines

The use of common corridors for several overhead transmission lines is widespread nowadays. The drawback of this solution is the intensification of electromagnetic interferences between power circuits of transmission lines in common corridors. Power circuit interactions can cause significant voltage disturbances in electrical networks with transmission lines sharing right of ways (ROWs) with power lines […]

A new fast peak current controller for transient voltage faults for power converters

Power converters are the basic unit for transient voltage fault ride through capability for most renewable distributed generators. When a transient fault happens, the grid voltage will drop suddenly, and probably, will also suffer a phase-jump event also. State of the art voltage fault control techniques regulate the current injected during the grid fault. However, […]

Voltage quality in the HV distribution grid

Voltage quality (VQ) analyzers are permanently installed in some 110kV substations in the Czech Republic. Selected VQ parameters are evaluated according to the EN 50160 standard when recorded data available from several years are analyzed.

Application of Remote Sensing Technologies to Map the Structural Geology of Central Region of Kenya

Advancements of digital image processes (DIP) and availability of multispectral and hyperspectral remote sensing data have greatly benefited mineral investigation, structure geology mapping, fault pattern, and landslide studies: site-specific landslide assessment and landslide quantification. The main objective of this research was to map the geology of the central region of Kenya using remote-sensing techniques to […]

Magnetic Field Sensor Based on Micro-fiber Sagnac Loop Interferometer and Ferrofluid

We demonstrate a novel compact optical magnetic field sensor composed of a single-mode micro-fiber sagnac loop interferometer (SMSLI) and ferrofluid (FF). The refractive index (RI) of FF cladding in the twist area of SMSLI is changed with the externally applied magnetic field, which makes the┬ádip- wavelength of the SMSLI transmission spectra shift. Experimental results show […]
