Unlike oil-filled transformers, dry-type transformers use air, gas, or solid insulation to cool the windings. This eliminates the risk of oil leaks and dramatically reduces fire hazards, making them ideal for indoor installations, high-rise buildings, hospitals, and transit systems.

What are Dry-Type Power Transformers (IEC 60076-11 / Formerly IEC 60726)?

(and later updated by the 2018 edition). While legacy documents referencing IEC 60726 may still exist, current industry standards require compliance with the IEC 60076-11 series for design, rating, and testing of dry-type power transformers up to 72.5 kV. Svenska institutet för standarder, SIS Key Information on IEC 60726 & Replacements Withdrawn and superseded by IEC 60076-11. Scope (Original IEC 60726):

Measurement of winding resistance, voltage ratio, impedance, no-load loss, and partial discharge. Type Tests: Temperature rise test, lightning impulse test.
