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.

          Clause 3 contains information for use with transformers rated below 10 MVA with high voltages less than 69 kV. Clause 4 applies to transformers rated 10 MVA and above with primary voltages of 69 kV and above, including EHV transformers.<br />\n
          NOTE 1: For transformers with primary voltages that are less than 69 kV and larger than 10 MVA, users should follow Clause 4.1<br />\n
          NOTE 2: The user should carefully read the instruction book supplied by the manufacturer. Any conflict with this guide that may occur should be resolved with the manufacturer for each specific installation.<br />\n
          This Guide intents to provide the users the procedures, criteria and current practices in the installation and maintenance of liquid immersed power transformers.
