It is imperative that your high voltage plants such as transformers and switchgear are in good condition. Regular analysis of the presence of gases in the oil used for insulation and heat conduction provides an accurate method of checking whether there are any internal issues. Gases that are dissolved in oil indicate combustion processes in the oil itself or insulation material. The combustion is caused by poor electrical connections, hot-spots, corona or sparks. CN Rood offers a range of options for tracing issues of this kind.
