Online FATs for power transformers due to current situation
The oil-immersed power transformers are designed and manufactured in accordance with the individual requirements of the customers. This makes each transformer unique. Its individual character, the complexity of construction and the high-quality standards require some tests before the production process is finalized.
The tests, called Factory Acceptance Tests, are normally done with the participation and supervision of a customer representative at the testing station. In recent weeks, as the COVID-19 pandemic is spreading around the world, the standard form of FATs has become impossible due to safety reasons. That is why R&S ZREW introduced online, live broadcast FATs.
Customer representatives have a live view of 3 cameras at the same time, which show a view of the transformer under testing, the team’s activities related to switching and calibrating the measuring system and the screen with the test results.
Some details about the first online FAT at R&S ZREW:
- Conducted in March 2020
- For one of the main distribution network operators in Poland
- 2 tested transformers with power rating 63/31,5/31,5 MVA and voltage 115/15,75/15,75 kV
