Introduction to 10kV Three-Phase Power Transformers

10kV three-phase power transformers are integral components in electrical power distribution, tasked with transforming voltage levels. They are widely used in industrial, commercial, and utility sectors to step up or step down voltages as needed for safe and efficient power distribution.

Core Features of 10kV Three-Phase Power Transformers

These transformers are designed to be robust, efficient, and reliable. Key features include:

• High Efficiency: Typically, these transformers have an efficiency rating of over 98%, minimizing energy losses during transmission.
• Durability: Constructed with high-quality materials to withstand various environmental conditions and ensure long operational life.
• Cooling System: Equipped with either air cooling (AN) or oil cooling (ONAN), depending on the operational requirements.
• Protection: Integrated with protective devices such as Buchholz relay, pressure relief devices, and overcurrent protection to prevent damage from electrical faults.

Technical Specifications

The following technical parameters are typical for 10kV three-phase power transformers:

• Rated Power: Ranges from 100 kVA to 1000 kVA, depending on the application.
• Primary Voltage: 10 kV, with a secondary voltage typically ranging from 400 V to 690 V.
• Frequency: Commonly 50 Hz or 60 Hz, matching the local power grid specifications.
• Impedance Voltage: Approximately 4% to 6% to ensure voltage stability under load changes.
• Temperature Rise: Normally, a maximum of 65°C for oil and 55°C for winding.
