Part , General.

Part , Temperature rise. Part , Insulation levels and dielectric tests. Part , Ability to withstand short circuit.

Annexes A and E form an integral part of this standard. Annexes B, C, D and F are for information only. When IEC standards do not exist for such categories of transformers, this part of IEC may still be applicable either as a whole or in part. For those categories of power transformers and reactors which have their own IEC standards, this part is applicable only to the extent in which it is specifically called up by cross-reference in the other standard.

Such agreement is to be made between the manufacturer and the downloadr. The matters should preferably be raised at an early stage and the agreements included in the contract specification.

NOTE This requirement is normally not critical in public supply systems but may have to be considered in installations with considerable convertor loading. Also note the importance of current harmonics for load loss and temperature rise. An environment not exposed to seismic disturbance which would otherwise require special consideration in the design.

These may be factors such as high altitude, extreme high or low temperature, tropical humidity, seismic activity, severe contamination, unusual voltage or load current wave shapes and intermittent loading. They may also concern conditions for shipment, storage and installation, such as weight or space limitations see annex A.
