These three-phase power transformers transfer energy between voltage levels in substations and industrial installations. The range spans 4–26 MVA; the voltage ratio is selected for the network and load.
Breathing construction combines an oil conservator, removable radiators and monitoring equipment. Available vector groups include Dyn11, YNd11 and YNyn0; the transformation ratio and tapping arrangement are defined for the project.
Monitoring equipment includes a Buchholz relay, oil-level indicator and dial thermometer. Performance and dimensions must be confirmed for the selected configuration.
Applications
- Power substations
- Industrial power distribution
- Voltage-level conversion
