50hz Furnace Transformer

Power Capacity: Typically ranges from 1 MVA to 120 MVA, depending on furnace size and application.
Primary Voltage: Up to 33 kV; common values include 6.6 kV, 11 kV, and 22 kV.
Secondary Voltage: Low voltage outputs, generally between 100 V to 1,000 V, to accommodate high current requirements.
Frequency: Standard operation at 50 Hz or 60 Hz.
Phase Configuration: Available in both single-phase and three-phase designs.
Vector Group: Commonly Dyn11, facilitating phase shift and grounding considerations.
2. Current and Impedance
Secondary Current: Designed to handle extremely high currents, often in the range of 10 kA to 60 kA, depending on furnace requirements.
Impedance Voltage: Typically between 4.5% and 21%, balancing voltage regulation and fault current limitations.
