When an isolation transformer is provided, one conductor of the secondary winding should be?

In the context of isolation transformers, grounding one conductor of the secondary winding plays a critical role in ensuring safety and functionality of electrical systems. When one side of the secondary winding is grounded, it establishes a reference point for the system. This helps in controlling voltage levels and reducing the risk of electric shock by providing a clear path for fault currents should a failure occur in the system.

Grounding the secondary winding also enhances the ability to detect faults and ensures that protective devices such as circuit breakers operate correctly by facilitating the dissipation of electrical currents that could otherwise pose a hazard. In many applications, especially in industrial and commercial settings, it is a standard practice to ground one side of the transformer to create a safer operating environment.

Therefore, the grounding of one conductor in the secondary winding of an isolation transformer is essential for safety, proper operation of electrical systems, and compliance with electrical codes and standards.
