Distribution system insulator monitoring using video surveillance and support vector machines for complex background images
Development of substation monitoring system (SMS) with improved features for substation automation purposes has become one of the potential areas of research particularly in developing countries like India. The unending SMS automation systems usually incorporate protection of the distribution system from different faults based on monitoring of parameters, such as voltage, current and so forth. ...

Characterisation of power quality disturbances based on wavelet transforms
This paper presents a new technique for detecting and characterising disturbances in power systems based on wavelet transforms. The voltage signal under investigation is often corrupted by noises, therefore the voltage signal is first denoised using wavelet thresholding and then wavelet transform is applied to the denoised signal. Using the first-level detail wavelet coefficients, the voltage ...

Redundant combustion plant for Novartis
Type HOFGAS®- IFM4c/2200/1500/60/180 Commissioning 2004 Site Novartis (Basel, CH) Situation In order to prevent production failure due to missing redundancy in the flue gas clean up, Novartis required an additional system. During different production processes exhaust air load with organic components is formed. This air is collected and delivered to a thermal vapour treatment (TVT). ...

Transformer oil purification
Why degas transformer oil? Maybe the first question should be, “why is it important to have purified oil in a transformer?” Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating--reducing the electrical efficiency and lifetime of the transformer. Likewise, water contamination at levels as low as 30 ppm (parts per million) can adversely affect the ...
