Monitoring transformer performance during the service is one of the most important subject were NEPCO was interested in, So that it works to develop the monitoring action by establishing laboratory that can doing all necessary tests for electrical insulating oil to know the specification for new and used oil according to the international standard method using in the specialist laboratories.
Constant monitoring of the quality of the insulating Oil is mandatory to ensure along service life for your transformer, Oil sample was taking by laboratories stuff by using modern techniques in collecting sample and according to ASTM D IEC to certify accurate results
Dissolved gas in transformer oil.
If it appears through the tests conducted on the electrical insulating oils that there are any problems, the laboratory can provide the service of treating the oil from dirt and moisture through the filtration process, and this is based on the customer’s request, which is useful in treating moisture and impurities and raising the insulation. In order to develop this service, the National Electric Power Company has purchased an oil regeneration plant, which is useful in adjusting the status of the oil in terms of acidity, surface tension and color.
