Transformers are a critical component of any electrical grid, and their installation requires a high level of expertise to ensure safety and functionality. The process involves more than just placing the unit. It typically begins with a detailed site assessment to select the correct type and capacity of the transformer, followed by the preparation of a secure foundation to support its weight. The physical installation includes the safe lifting and positioning of the unit, as well as the meticulous connection of all high and low-voltage cables. Finally, a series of pre-commissioning tests are conducted to verify its insulation, winding resistance, and overall operational parameters before the transformer is energized and put into service. This rigorous process is crucial for preventing future faults and ensuring the long-term reliability of the power system.
