ageing of transformer

ageing of transformer

ageing of transformer

(OP)
How does the ageing affect the core loss and cu loss of distribution transformer ?

1. because of short circuit and other high loading causes carbon particles to be formed and deteriorates the core properties ? (is it right ?)

2. Because of harmonics ,
What else

Somewhere I read or heard (forgot ) , at later part of transformer life, losses increases ?
Can anybody give me clear thought of why ? does it happens ?

RE: ageing of transformer

1. Not that I know of.
2. Only if harmonics cause overheating.

RE: ageing of transformer

As your oil deteriorates, it can increase losses, as the power factor of the oil increases, so more resistive losses in the oil, so more losses overall.
