How is the secondary winding of an isolation transformer configured?

The secondary winding of an isolation transformer is configured with a grounded conductor to enhance safety and ensure proper grounding. This configuration provides a reference point for the voltage levels on the secondary side and helps prevent electrical shock hazards. Grounding helps mitigate the risk of overvoltage conditions that could occur due to transient events or faults.

In practical applications, grounding the secondary winding creates a stable and safe environment for connected equipment, allowing for proper operation and reducing the likelihood of damage or malfunction. This is particularly important in environments where sensitive electronics are used, as it helps to stabilize the electrical system and protect against electrical interference.

The other options are less applicable in this context. While complete isolation and full insulation are characteristics of isolation transformers, they do not necessarily imply grounding, which is crucial for safety and performance. An adjustable connector is not a standard feature of how the secondary winding is configured in isolation transformers.
