Power Transformer Testing Cycle 1. Generally speaking, the high-voltage test of a transformer is a non-destructive test, and increasing the number of tests will not cause harm to the transformer. Therefore, testing once a year is a wise choice for important users. 2. According to the requirements of DL/T 596-2005 "Preventive Testing Regulations for Power Equipment", the normal testing cycle for 10kV power transformers is once every 1-3 years. However, if necessary, the testing cycle can be shortened to once every year. 3. With the progress of materials science and the development of modern manufacturing technology, electrical equipment is developing towards long-term, maintenance free, and condition based maintenance. In the future, it is expected to develop into a stage of years of maintenance or no maintenance. 4. Some enterprises use relay protection devices for control and protection of 10kV transformers, which have relatively large capacity and are relatively important. But the fixed value of the protection device requires verification once a year, so many units carry out transformer tests during protection verification and power outage. Baijian can provide various equipment testing services such as consumer material testing according to corresponding testing standards, and can also design solutions based on customer needs to provide non-standard testing services for customers. Baijian Testing is a comprehensive third-party testing agency that provides customers with one-stop testing services and green solutions. If you have testing needs, please feel free to inquire at any time. Testing cycle: 7-15 working days to issue testing equipment testing reports. Testing fee: Free initial testing, quoted based on customer testing needs and experimental complexity. Sample size: The specific sample size needs to be determined based on the customer's testing project, and you can consult an engineer
