Silicone Oil Mist 11KV Transformer - Remedies?

Is there a manufacturers data plate on your existing transformer.

This plate should contain the manufacturers name and perhaps even an address and/or other contact info.

The transformer manufacturer would be the best place to get repair or replacement advice.

The manufacturer had closed down its factory 4 years ago and we are left to resolve this issue head on the worries are explosion??? degradation of leaky areas ( actually seen with black wet oil marks mixed with dust)

The quickest solution is replacement which are in the planning works but at the mean time any patch up remedies are welcome

Contact the replacement transformers' manufacturer for advice.

Hi

thanks

we are considering dry type from Siemens but local power co preferred the oil type so have the pros and cons

most of third party advice is replacement but im just curious if theres really a need to replace if we seal the leaks by new technologies???

Hi

thanks for the quick response

the only way is replacement but still seek new technolgies that can handle leaks ( oil breathing as they say) no drip at the moment but only pock marks of wet oil marks mixed with dust.... some power company had tightened one bushing live just to eliminate the leak mostly on top of the transformer

hi

thanks for the info

will inquire on our situation if they have a solution

Probably not unless the leaks are in a flat piece of metal.

I suggest that you contact several transformer suppliers and let their engineering/sales force help you justify a new unit.

Good luck!

you read my mind

the leaks are everywhere from the bushing coupling joint, temperature coupling joint, some edge of the fins .......

The manufacturer's choice is replacement which we will do my boss is just asking

a good justification to hasten the process of changing the transformers

thanks for the advice

Hi thanks for the info this is the same conclusion made in our last meeting poor quality and gaskets replaced 4 years ago

Humidity is high even if its indoor and dust has very high accumulation so replacement is the only choice good points for justification as the manufacturer had bad record when it comes to their products mostly transformers...

yours can add up to my justification

thanks for the support

If you're determined to go down the road of replacement I would adopt a slightly different approach. Have the first unit replaced with a new oil filled unit. The removed unit I would have refurbished by a reputable company. Once done, use this the replace the second unit. And so on until all are replaced. The last unit becomes a spare for the future.

The key is finding a reputable company to do the refurbishment. If you were in the UK I could point you in the right direction.

8 years old transformers showing same signs of defects good idea for refurbishment the problem is who will do with guarranty and safeguards that the leaks will appear in other areas of the transformer

Oil and dry type pros and cons please....

thanks for the ideas and will copy paste for submission to my boss lol
