1. The measurement should generally be performed after the oil temperature has stabilized. Only after the oil temperature is stable, the oil temperature can be equal to the winding temperature, and the measurement result will not cause temperature conversion errors due to temperature differences.For
GDRZ-902 Transformer Sweep Frequency Response SFRA Analyzer is used to check the frequency response data of transformer winding.
Transformer oil mainly plays a role of insulation and cooling during the operation of power transformers. Therefore, transformer oil must have a certain electrical insulation strength during the operation of power transformers. In order to ensure the safe and reliable operation of power transformers
