Precautions to Take When Installing a Transformer
We have installed and serviced for the world's leading transformer manufacturers. With more than 15 years of experience, we can service, repair or install transformers of all voltage and MVA classes.

Installing a transformer requires careful planning and adherence to safety guidelines to ensure a successful and safe installation. Here are some precautions to consider when installing a transformer:

  1. Safety Gear: Wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and protective clothing to protect yourself from electrical hazards.

  2. Qualified Personnel: Ensure that the installation is carried out by qualified and trained personnel who have the necessary knowledge and experience in working with transformers.

  3. Site Preparation: Prepare the installation site by clearing it of any debris or obstacles that could hinder the installation process. Ensure there is adequate space for the transformer and that it is located in a well-ventilated area.

  4. Electrical Isolation: Before beginning the installation, ensure that the power source is switched off and properly isolated to prevent any accidental energization during the installation process.

  5. Load Calculation: Determine the correct transformer size and capacity based on the load requirements. Improper sizing can lead to inefficient operation and potential hazards.

  6. Proper Lifting Equipment: Use appropriate lifting equipment, such as cranes or forklifts, to handle and position the transformer safely. Ensure that the lifting equipment is in good working condition and operated by trained personnel.

  7. Secure Mounting: Securely mount the transformer using proper structural support, ensuring that it is level and stable. Follow manufacturer's instructions for installation and use appropriate mounting hardware.

  8. Correct Electrical Connections: Follow electrical connection diagrams provided by the transformer manufacturer, ensuring that all connections are properly made and tightened. Check for proper grounding and ensure that all electrical connections comply with local electrical codes and regulations.

  9. Cooling and Ventilation: Ensure proper cooling and ventilation systems are in place to dissipate heat generated by the transformer. Maintain sufficient clearance around the transformer to allow for adequate airflow.

  10. Testing and Commissioning: After installation, conduct thorough testing and commissioning procedures to verify that the transformer is functioning correctly and safely. This may include insulation resistance testing, winding resistance measurement, and checking for proper voltage regulation.
