Transformer oil is an essential component in the operation of electrical power systems. It acts as a coolant and insulator to prevent electrical arcing and ensure the reliable and safe operation of the transformer. However, with time and use, transformer oil can deteriorate, causing a decrease in its insulating properties and overall effectiveness. This is why regular oil dielectric strength tests, also known as oil BDV (breakdown voltage) tests, are necessary to ensure the oil is performing at the necessary level.
Oil dielectric strength refers to the ability of transformer oil to withstand voltage stress without breaking down. This is an important characteristic, as voltage surges or electrical faults can occur with little warning, putting equipment and personnel in danger. Therefore, the oil BDV test is performed to determine the minimum voltage required to cause a breakdown in the oil, which helps detect potential issues before they become critical.
The oil BDV test involves applying a gradually increasing voltage to a sample of transformer oil until it breaks down, with the process being carried out under controlled conditions according to standardized procedures. The result is then compared to the acceptable threshold for the particular type of transformer oil being tested.
According to the relevant provisions of the national standard GB507-1986 and the line standard DL/T846.7-2004, we have given full play to our own advantages and carefully developed high accuracy and full digital industrial instruments-the oil BDV tester, after many field tests and long-term unremitting efforts. In order to meet the needs of different users, this series of instruments can be divided into single cup three cups, and multi-cup models. The instrument is easy to operate and beautiful in shape. Due to the use of automatic digital microcomputer control, the measurement accuracy is high, anti-interference ability is strong, safe, and reliable. It can do the oil dielectric strength test and maintain the transformer oil.
