The test procedure is performed in a specified apparatus, where the oil sample is subjected to an increasing AC electrical field until breakdown occurs. The Ceylon Electricity Board now offers Electricity consumers the option of receiving a number of SMS based services such as the following.

Views Read Edit View history. To assess the insulating property of dielectric transformer oil, a sample of the transformer oil is taken and its breakdown voltage is measured.
Do you need a multi-user copy? This is because it tends to deteriorate over time. Through such testing, transformers’ life can be substantially increased, thus delaying new investment of replacement transformer assets. The lower the resulting breakdown voltage, the poorer the quality of the transformer oil. September Learn how and when to remove this template message.

Transformer oil testing – Wikipedia
Preview Abstract IEC As transformer oil deteriorates through aging and moisture 6015, transformer oil should, depending on economics, transformer duty and other factors, be tested periodically. This edition constitutes a technical revision and, mainly, confirms the content of the previous edition even if some advances are included.
