What is a common practice when installing a new transformer?

A common practice when installing a new transformer involves placing all supporting bolts before the installation process is completed. This step is critical because it ensures that the transformer is securely mounted and stable, which is essential for both functional and safety reasons. Properly securing the transformer helps prevent vibrations and movement that could lead to mechanical failures or damage.

Additionally, securing the transformer helps in maintaining alignment with various components such as electrical wiring, oil containment systems, and cooling mechanisms. Ensuring that all supporting bolts are in place before further electrical connections or operational tests are performed is also a fundamental safety precaution, minimizing the risk of accidents or malfunctions during the transformer’s operation.

While other practices like connecting customers, ensuring insulation in the surrounding area, or checking voltage levels are also important aspects of transformer installation and operation, they occur at different stages or under different conditions and do not directly relate to the initial mechanical setup that requires securing the transformer first.
