The recommendations presented in this guide apply to the inspection@ installation@ and maintenance of liquid-immersed power transformers rated 501 kVA and above with secondary voltages of 1000 V and above. This guide covers the entire range of power transformers@ including extra high-voltage (EHV) transformers. This guide does not cover special transformers such as furnace transformers@ rectifier transformers@ etc. Distinctions are made as required for various MVA ratings@ voltage ratings@ and types of liquid insulation. The manufacturer??s instruction manual should be the primary reference for transformer inspection@ installation and maintenance especially while the equipment is under warranty. This guide should be used in conjunction to supplement the manufacturer??s instruction manual@ or as a substitute when it is not available. Clause 4 contains information for use with transformers rated below 10 MVA with high voltages less than 69 kV. Clause 5 applies to transformers rated 10 MVA and above with high voltages of 69 kV and above@ including EHV transformers. For transformers with high voltages that are less than 69 kV and larger than or equal to 10 MVA@ users should follow clause 5.0.
