Photovoltaic panel Spice modelling

The paper presents a universal Spice model that can be used for modelling the photovoltaic panels (PV) – namely the DC characteristics. The model was built on simplified schematic and fitting its parameters to the measured data. There were developed two types of the models...

Transformer fault detection based on Raman analysis of the transformer oil (A case study)

The paper reports on an experiment in the academic laboratory that aimed to detect a transformer fault by Raman spectroscopy of the transformer oil. Indicators of oil degradation (eg gases, sludge, cellulose) could not be detected. Combustion indicators (soot – graphitic particles, grap...
