(1) High-voltage transformers must be rotated at least once every 10 years. In certain cases, a field inspection can be conducted as an alternative to full rotation, provided it meets the required standards and documentation.
(2) Low-voltage current transformers are required to be rotated at least once every 20 years. This interval ensures that the accuracy and reliability of the measurements remain consistent over time.
It is important to maintain proper records of all rotations and inspections to ensure compliance with safety regulations and operational efficiency. Regular maintenance and monitoring also help in identifying potential issues before they escalate into more serious problems. Following these guidelines not only extends the lifespan of the equipment but also enhances overall system performance and safety.
