Attach the oil test report — dissolved gas analysis, and whatever else you hold — and tell us what the transformer is, how it is loaded, and what prompted the enquiry. Where a short answer is possible, we will give you one. Where it is not, we will write you a note on what it would take to establish an answer.
If there is no result yet, or the enquiry is about something other than one — sampling, an inspection, a life assessment, a test programme, training — contact us instead.
Sent. We will get back to you soon.
Your enquiry arrived; the files did not. Send them to marius@grisaru.com and we will read them with it.
