摘要：

This article will discuss the key applicable North American standards defining performance, testing, installation, and routine field maintenance of liquid-immersed distribution substation transformers. These transformers, typically applied in commercial and industrial power systems, can be installed either in outdoor or indoor locations, applied as remote or close-coupled to either primary or secondary switchgear, or both. Typical ratings for these distribution substation transformers range from 112.5 kVA through 10,000 kVA three-phase, at 50 or 60 H, with primary voltage at 34,500 V and below and secondary voltage at 6,900 V and below. Not included in the scope of this article are dry-type distribution transformers, pad-mounted distribution transformers, or power transformers with ratings up to 100,000 kVA and 230 kV. Recommendations based on these standards for selection, installation, and factory/field-testing industry users should specify to maximize reliability, operational efficiency, and safety will follow.
