What you will learn here:
- Provide an understanding of Vibration Analysis used to determine the clamping pressures (tightness) of an oil filled power transformer
- Frequencies used to determine looseness
- Core form vs Shell form: determining where to take readings and the importance of follow up readings
- Vibration Analysis of oil circulation pumps in the cooling system will also be provided
- Ultrasonic (acoustic emission) analysis of transformer main windings and pumps/motors
- Sound Level Analysis of oil filled power transformers and how the sound levels relate to core tightness
- A weighting vs C weighting
- Determining where to take the sound level readings
Keywords: vibration analysis, sound level analysis, frequency shift, core form, shell form, A weighting vs C weighting
