Site Selection:

• Choose a suitable location that complies with safety regulations and allows for proper ventilation.

• Ensure accessibility for maintenance and future repairs.

Transformer Sizing:

• Determine the appropriate size and rating of the transformer based on the load requirements.

• Consider factors such as future load growth and potential expansions.

Foundation Preparation:

• Construct a stable foundation that can support the weight of the transformer.

• Ensure the foundation is level and provides proper drainage.

Transportation and Handling:

• Transport the transformer to the installation site using appropriate equipment and following safety protocols.

• Use cranes or other lifting devices to handle the transformer carefully.

Mounting the Transformer:

• Place the transformer on its foundation securely.

• Use vibration isolation pads or other measures to reduce vibration and noise.

Electrical Connections:

• Connect the primary and secondary windings of the transformer to the electrical system.

• Follow the manufacturer’s guidelines for proper wiring and connections.

Grounding:

• Ensure proper grounding of the transformer for safety.

• Connect the transformer’s grounding terminal to the ground grid.

Oil Filling (for Oil-Immersed Transformers):

• If the transformer is oil-immersed, fill it with the appropriate transformer oil according to manufacturer specifications.

• Monitor the oil level and perform any necessary tests.

Cooling System Installation:

• Install cooling systems if required, such as fans or radiators.

• Ensure proper airflow around the transformer to maintain optimal operating temperatures.

Testing:

• Conduct routine tests, including insulation resistance tests, turns ratio tests, and vector group tests.

• Perform a dielectric withstand test (megger test) to check insulation integrity.

Protection and Control Systems:

• Install protective devices and control systems based on the specific requirements of the transformer.

• Configure relays, monitoring systems, and any necessary automation.

Labeling and Documentation:

• Label all terminals, conductors, and controls for clarity.

• Maintain comprehensive documentation, including wiring diagrams, test reports, and operating instructions.

Energizing the Transformer:

• Gradually energize the transformer, monitoring for any abnormal conditions.

• Check for proper voltage regulation and load distribution.

 
Functional Testing:

• Perform functional tests to ensure that protection and control systems operate as intended.

• Verify that the transformer meets specified performance criteria.

Maintenance Plan:

• Establish a regular maintenance schedule, including oil testing, inspections, and cleaning.

• Keep records of maintenance activities for future reference.

Safety Measures:

• Implement safety protocols for personnel working in the vicinity of the transformer.

• Display warning signs and provide proper safety equipment.
