Pollution test station Glogow, twenty years of research

Chrzan, K L (Wroclaw University of Technology, Poland)


Abstract: The evaluation of electrical stress of polluted outdoor insulators was carried out at the field test station located at a copper smelting plant Głogów in 1987 and 2002. Leakage current and flashover voltages were recorded on porcelain long rods of different types. A simple impulse counters having three different trigger levels were used for current measurements. The special fuses with an explosion mixture were applied for detection of flashovers. Additionally, the measurements of ESDD on insulator surface or dust deposition density were carried out. During last ten years the industry dust emission in Middle Europe decreased considerably due to progress in environmental protection. Therefore the similar measurements were repeated with the aim to asses the current state of electrical stress of outdoor insulators.
