SFSZ11-40 MVA 110 KV Power Transformer with de-energized tap-changer

 

Oil for transformer and tap-changer Type and quality

 

Only new naphthenic-based oils, which must be certified as such prior to filling, shall be used.

 

Where the first filling of virgin oil is to be supplied by the contractor, the oil shall at least be as specified NRS 079, without any additive. The colour coding of the drums containing the oil shall comply with the requirements of NRS 079.

 

Under no circumstances shall poor quality oil be filled into the transformer and only thereafter be brought up to specification by circulation within the transformer.

 

Dielectric strength

 

The power frequency dielectric breakdown strength of the oil in any part of the transformer and on- load tap-changer shall meet the transformer manufacturer's requirement. But shall, in any case, not be less than 70 kV/2,5 mm for virgin oil prior to filling and not be less than 60 kV/2,5 mm at time of take over.

 

Dielectric strength shall be determined in accordance with the method prescribed in IEC 60156.
