Transformer predictive failure analysis??
modes in which transformer fails to work
Failure in circuit breaker
Winding shorted due to insulation failure
Abnormal temperature rise number
List out the qualification tests for transformer
How to detect the test parameters???
Temperature - Humidity test
Di-electric breakdown
Surge insulation
Winding surge test
Line swell test
Internal circuit breaker
Line load regulation
Temperature rise test
Vibration test
Life of transformer - Life of circuit breaker??? CB part number: W28-XQ1A-5 is by TYCO ELECTRONICS CORP - QVNU2 - E69543-
Parameters to consider
1) Temperature - Humidity
2) Internal circuit breaker
3) Line load regulation
4) Temperature rise test
5) Vibration test
1) what is the max working ambient of transformer
2) What will happen if the transformer is allowed to work continuously in high ambient
predicting the life of circuit breaker
1) calculating the dip in voltage. Due to ageing does the dip goes beyond specified value?
2) Find the relation between this value and life of transformer.
Temperature rise number VS life of transformer
Vibration vs life of transformer
