Anotace
This part of IEC 60076 applies to power transformers with the exception of certain categories of small and special transformers such as:
– transformers with rated power less than 1 kVA per phase;
– transformers which have no windings with a highest voltage for equipment with a Um higher than 1 000 V;
– instrument transformers;
– traction transformers mounted on rolling stock;
– starting transformers;
– testing transformers;
– welding transformers;
– explosion-proof and mining transformers;
– transformers for deep water (submerged) applications;
– transformers covered by the scope of TC96.
When IEC standards do not exist for such categories of transformers (in particular transformers which have no windings with a highest voltage for equipment with a Um higher than 1 000 V for industrial applications), this part of IEC 60076 may still be applicable either as a whole or in part.
This standard does not address the requirements that would make a transformer suitable for mounting in a position accessible to the general public.
For those categories of power transformers and reactors which have their own IEC standards, this part is applicable to the extent to which it is specifically called up by cross-reference in the other standard. Such standards exist for:
– reactors (IEC 60076-6);
– dry-type transformers (IEC 60076-11);
– self-protected transformers (IEC 60076-13);
– gas-filled power transformers (IEC 60076-15);
– transformers for wind turbine applications (IEC/IEEE 60076-16);
– traction transformers and inductors on board rolling stock (IEC 60310);
– converter transformers for industrial applications (IEC 61378-1);
– converter transformers for HVDC applications (IEC/IEEE 60076-57-129);
– phase-shifting transformers (IEC/IEEE 60076-57-1202);
– voltage regulated distribution transformers (IEC 60076-24).
At several places in this part it is specified or recommended that an 'agreement' should be reached concerning alternative or additional technical solutions or procedures. Such agreement is made between the manufacturer and the customer. The matters should preferably be raised at an early stage and the agreements included in the contract specification.
