A 15 KVA Three-Phase Auto Transformer is a type of electrical transformer used to step up or step down voltage in three-phase power systems. It is designed to efficiently transfer electrical energy between circuits with a single winding, making it compact and cost-effective. This transformer is commonly used in industrial, commercial, and power distribution applications.

• Capacity: 15 KVA
• Phase: Three-phase
• Input Voltage: As per customer requirements (e.g., 480V, 415V, 380V, 230V)
• Output Voltage: Adjustable based on application (e.g., 400V, 208V, 220V)
• Frequency: 50Hz / 60Hz
• Cooling Type: Air-cooled or oil-cooled (depending on model)
• Efficiency: >98%
• Insulation Class: Class F or Class H
• Winding Material: High-quality copper or aluminum
• Voltage Regulation: ±1% or better
• Protection: Overload, short circuit, and overheating protection
• Mounting Type: Floor-mounted or wall-mounted

• Compact and Lightweight Design: Requires less space compared to an isolation transformer.
• High Efficiency: Reduces power losses and improves energy efficiency.
• Reliable Performance: Designed for continuous operation with minimal maintenance.
• Cost-Effective: Uses a common winding for both primary and secondary voltage, reducing material and cost.
• Low Impedance: Provides better voltage stability and regulation.
• Customizable Voltages: Can be designed to meet specific voltage conversion needs.

Unlike conventional isolation transformers, an auto transformer has a single winding with taps at different points to provide the required voltage levels. It operates by transferring electrical energy through both conduction and induction, making it more efficient with lower copper losses.

• Industrial machinery requiring different voltage levels
• Power distribution in commercial buildings
• Voltage adjustment for imported/exported equipment
• Generator and motor applications
• HVAC systems and electrical testing setups
