IEEE (112.00, SecHon 9.2 Tolerances for impedance The tolerances for impedance shall be as follows: a) The impedance of a two -winding transformer with an impedance voltage greater than 2.5%shall have a tolerance of ±7.5%of the spedfied value, and those with an impedance voltage of 2.5% or less shall have a tolerance of ±10%of the specified value. l Differences of impedance between duplicate two -winding transformers, when two or more units of a given rating are produced by one manufacturer at the same time, shall not exceed 7.5%of the specified value b) The Impedance of a transformer having three or more windings, or having zigzag windings, shall have a tolerance of ±10%of the specified value. Differences of impedance between duplicate three -winding or zigzag transformers, when two or more units of a given rating are produced by one manufacturer at fine same time, shall not exceed 10%of the specified value. c) The impedance of an autob ansformer shall have a tolerance of ±10%of the specified value. Differences of impedance between duplicate autetrandurmers, when two or more units of a given racing are produced by one manufadu rer at the same time, shall not exceed lo% of the specified value. d) Transformers shall be considered suitable for operation in parallel when reactances come within the limitations of the preceding paragraphs, provided that tums ratios and other controlling characteristics are suitable for such operation. 3 Phase Padmounled Transformer Bid Evaluation e Units 6 lf/mr Type 3p NO Old S: Size $00 kVA SecondaryV IY&2m Mle: NL Loss C d $ 390 WOCk A T3(x10Y, FL Loss Coat $ 230 $pacified Impedance % 3 oa (Sass Impedance Raqu(remeMa Table in Specification) Includes Wlndng's Losses Stray Loss89 g Losses a9saiatetl Aenscoted Win Winding's with Baao Bid flank Based on Flank Sued on Base Bid Guu No Guar Taal Aukliery Dovkes IYes / Stray Aucliary Impedance Extended Cast NL LaeNL FL Less' FL Bid it is 1»sl Evaluated lust I I SuppBr mmwf " $ / Each DWWka Lied Loss Guar Fug Lesd Las Impedance N I Steve?

IEEE C57.12.00, Section 9.2 Toieonces for Impedance The tolerances for Impedance shall be as follows: a) The impedance of a two -wilding transformer with an impedance voltage greater than 2,5%shall have a tolerance of 0.5%of the sped0ed value, and Nose with an impedance voltage of 2.5%or less shall have a tolerance of d10%of the specified value. Differences of impedance between duplicate two -winding transformers, when two a more units of a given rating are produced by one manufacturer at the same time, shall not exceed 7.5%of the specified value. b) The impedance of a transformer having three or more windings, or having zigzag windings, shall have a tolerance of t10%of the specified value. Differences of impedance between duplicate three -winding or zigzag transformers, when two or more units of a given rating are produced by one manufacturer at the same time, shall not exceed 10%of the specified value. c) The impedance of an autotransfonner shall have a tolerance of t10%of Me specified value. Differences of impedance between duplicate autonewformers, when two or more units of a given rating are produced by one manufacturer at the same time, shall not exceed M of the specified value. it Transformers shall be considered suitable for operation in parallel when reactances come within the limitations of the preceding paragraphs, provided that turns radios and other controlling characteristics are suitable for such operation.
