2 TriDry Transformer An advanced d design with advanced d technology ABB s new TriDry transformer concept revolutionizes new thinking in the field of dry-type transformers A special core construction leads to significant product features TriDry completes ABB s dry-type yp transformer portfolio Premium features in a compact design! July, Slide

3 TriDry Transformer: compact I Triangular configuration gives excellence Magnetization of TriDry core A symmetrical, three-phase magnetic circuit => the symmetry of a -phase systems is preserved Wound core technology, continuously wound, without air-gaps, reducing the magnetic reluctance (resistance) of the core Optimized utilization of the core material in terms of magnetic flux distribution Almost round leg shape with 96% fillfactor of the core leg circle Results in a compact transformer July, Slide

4 TriDry Transformer: compact II Smaller footprint t enables broader varities of installation ti 5 kva transformer footprint TriDry Traditional e-core Characteristics: Smaller footprint (approx. 5 % less square footage) Length reduced Square footprint t form factor allows large variety of bus coordination options D views of TriDry model July, Slide

5 TriDry Transformer: compact III Reduced d weight for transport, t handling and installation ti Easier handling More efficient transport Simplified installation Matching characteristics: TriDry transformers are % lighter! July, Slide 5

6 TriDry Transformer: efficient I Reduced d no-load losses provide a competitive solution The core material is used in a highly efficient manner and saves on natural resources C B Y-axis: Annual costs (EUR) X-axsis: Transformer power rating (kva) *Base: 876 h operation per year Costs of no-load loss per year* (.5 EUR/kWh) 5 5 Characteristics: Reduced no-load losses TriDry transformers meet the more stringent no-load losses of the B loss class* almost naturally Transformers are often run at low load, therefore no-load losses play an important role in energy efficiency and operation costs A premium feature for a standard transformer without the premium cost 6 8. *according to EN55- July, Slide 6

7 TriDry Transformer: efficient II Savings due to reduced d operational costs No-load loss (NLL) A -5% A B C B k EcoDry Basic Standard Load loss (LL) A k TriDry A k % EcoDry Ultra EcoDry 99Plus Higher efficiency levels of TriDry compared to standard transformers More efficient units reduce operational costs during the transformer s life cycle A competitive, environment-friendly solution Transformer efficiency according to Class B B k! July, Slide 7

8 TriDry Transformer: premium features I Ti Triangular core leads to notable advantages Reduced harmonics Measurements of the harmonic content in the excitation current of TriDry transformers indicate strongly reduced harmonics in comparison to standard stacked core transformers even in the absence of a delta winding Measured harmonics in secondary current (% excitation, Dy-connection) % 5% % 5% % TriDry Stacked Core Y-axis: Harmonic content t X-axsis: Number of harmonics Reduced inrush current ABB tested for inrush current with positive and negative remaining magnetization (remanence). Tests on similar units indicate a strongly reduced inrush current for the TriDry transformer Inrush comparison Negative negative Bias Positive positive Bias TriDry Stacked Core Y-axis: Multiple of primary current X-axsis: Initial current direction July, Slide 8

9 TriDry Transformer: premium features II Ti Triangular core leads to notable advantages Reduced sound level The unique features of the core result in noise level improvements of 5- db compared to standard-grade steel. Improved EMC The compact and symmetrical coil arrangement results in a greatly reduced electromagnetic stray field around the transformer. July, Slide 9

10 TriDry Transformer: premium features III Comparison magnetic fields TriDry vs. standard d transformer kva, kv - - TriDry Brms / T > e-5 e-5 - e-5 e-6 - e-5 e-6 - e-6 r St tandard tran nsforme July, Slide

11 TriDry Transformer Product s special characteristics ti TriDry: Front view Standards: IEC676-: Product Scope: Ratings: kva up to 5 kva Voltage levels: kv up to kv TriDry: Bird s eye view Ambient: Indoor, 5 C up to + C Insulation Class: F July, Slide

12 TriDry Transformer: the premium without the premium Fast delivery times due to standardized di d ratings Four ratings, 6, 8 and kva for kv and kv will be available in stock Delivery within two weeks Delivery times and voltage levels for other ratings upon request Premium transformers without t a premium price, plus short delivery times! July, Slide

13 TriDry Transformer Customers benefits Compact: different and more compact footprint, less weight and length Efficient: % lower no-load loss at same material usage or up to % lighter for certain efficiencies Safe: all the advantages of dry-type insulation in a robust, symmetrical package Short delivery times: thanks to standardization; di ti most of the common ratings in stock July, Slide
