Energy Efficiency Regulations, 2016 (SOR/2016-311)

Marginal note:Energy efficiency standards — three-phase and 1.2 kV voltage class

• 705.2 (1) In respect of dry-type transformers that are three-phase, in the 1.2 kV voltage class and manufactured on or after January 1, 2016, the energy efficiency standards set out column 2 of Table 1 to this section apply to dry-type transformers that have a kVA rating set out in column 1.

• Marginal note:Energy efficiency standards — three-phase and voltage class greater than 1.2 kV

  (2) In respect of dry-type transformers that are three-phase, in a voltage class greater than 1.2 kV and manufactured on or after January 1, 2016, the energy efficiency standards that are set out in relation to the product’s BIL rating set out in column 2 of Table 2 to this section apply to dry-type transformers that have a kVA rating set out in column 1.

• Marginal note:Interpolation

  (3) For the purposes of subsections (1) and (2), if the kVA rating of the product falls between the kVA ratings set out in two consecutive items in column 1 of the applicable table to this section, the energy efficiency standard for the product is an interpolation of the corresponding energy efficiency standards set out in column 2.

• Marginal note:Reduced energy efficiency standard

  (4) The energy efficiency standard that is applicable to a dry-type transformer under this section is reduced by 0.11 if the transformer has multiple high-voltage windings and a voltage ratio other than 2:1.

• Marginal note:Testing standard

  (5) A dry-type transformer complies with the energy efficiency standard if it meets that standard when tested in accordance with testing procedures established by 10 C.F.R. Appendix A that are applicable to a dry-type transformer as defined in section 703.
