profile
This chapter includes a summary of the main specifications made by power utilities and large users of electricity. It is explained why the more efficient specification is just the IEC technical standard with a few additions. We show typical errors that occur when the company instead of referring to standards, prepare texts with unverifiable requirements. Examples will be used for main substation equipment. The concepts of the main type tests included in the bids are presented.
