Power Transformer Datasheet

Released: 15/7/2024 18:57:01   Visits:1824

A power transformer's datasheet is a comprehensive document that outlines the technical specifications, performance characteristics, and operating parameters of the transformer. It serves as a critical reference for engineers, designers, and technicians during the selection, installation, and maintenance of the transformer. Key elements typically included in a power transformer datasheet are:

  1. General Information: This section provides an overview of the transformer, including model number, type (e.g., single-phase or three-phase), cooling method (e.g., oil-immersed, air-cooled), and intended application (e.g., distribution, power generation).

  2. Electrical Specifications:

    • Voltage Ratio: The primary and secondary voltage ratings.

    • Rated Capacity: The maximum kVA or MVA the transformer can handle continuously without overheating.

    • Vector Group: Describes the phase relationship between primary and secondary windings.

    • No-Load Losses and Current: Power consumed and current drawn when the transformer is energized but not delivering power.

    • Short-Circuit Impedance: A measure of how the transformer impedes short-circuit currents.

  3. Thermal Characteristics:

    • Temperature Rise: The allowable increase in temperature above ambient conditions during operation.

    • Cooling Requirements: Details about cooling systems and oil/air flow rates if applicable.

  4. Dimensions and Weight: Physical dimensions (length, width, height) and weight of the transformer.

  5. Insulation and Protection:

    • Insulation Class: Specifies the maximum temperature rating of the insulation materials.

    • Protection Devices: Information on built-in protection like Buchholz relay, temperature sensors, etc.

  6. Connections and Terminals: Diagrams and descriptions of wiring connections and terminal arrangements.

  7. Performance Curves: Graphs showing the transformer's efficiency, load loss, impedance, and other performance parameters over a range of operating conditions.

  8. Standards Compliance: Lists the national or international standards the transformer complies with (e.g., IEC, ANSI, IEEE).

  9. Installation and Maintenance Guidelines: Instructions for proper installation, grounding, ventilation, and routine maintenance.

  10. Warranty and Safety Information: Manufacturer's warranty details and important safety precautions during handling and operation.
