Yonder converter duty transformers are suitable for complex power conversion systems. We offer transformers up to a rating of up to 25kVA in our range of turnkey solution for Hydrogen Generation
We utilise the latest design, measurement, and testing tools to ensure each transformer meets and exceeds the latest industry standards, as well as operational and customer specifications. Our in-house capabilities include multi-secondary, star and extended-delta transformer design. Our converter transformers are manufactured after carefully performing seismic analysis and short circuit calculation.
Specification | Yonder Offers |
Input | 6.6 kV, 11 kV, 22 kV, 33 kV |
Connection | Primary, star, delta or extended delta connection |
Output | 2 – 27 secondary windings (up to 64 in exceptional requirements) |
Vector group | -25 degrees to +25 degrees (5-degree variations) Extended delta on LV windings create different angles
|
Voltage Pulses | Through use of different angles, different number of pulses can be achieved (12-48 pulses) |
Type | Oil type Dry type, VPI (upto 10 MVA) |
Cooling | Natural cooling (ONAN) or forced cooling (AF) or Oil-filled Transformers Air cooling with directed air flow for Dry Type Transformers* |
Efficiency | 99% for large transformers 98% for transformers up to 1 kVA |
Harmonics Control | Copper shield between HV and LV windings to contain harmonics to secondary load and not reflecting on primary |
Winding Material | Copper foil as a conductor in LV winding or thinner conductor to keep Eddy current loss limited |
Tap Changers | Off-circuit tap links can be provided on HV side |
