    • (b) for the purpose of section 705, if it has a BIL of more than 150 kV and was manufactured before January 1, 2010.

Marginal note:Energy efficiency standards
  •  (1) The energy efficiency standards set out in column 2 of the table to this section apply to dry-type transformers that are manufactured during the periods set out in column 3.

  • Marginal note:Testing standard

    (2) A dry-type transformer complies with the energy efficiency standard if it meets that standard when tested in accordance with testing procedures established by the standard referred to in column 1 that are applicable to a dry-type transformer as defined in section 703.
