Which of the following is a benefit of isolating transformers in a 3-phase bank?

Isolating transformers in a 3-phase bank provide increased reliability of the system due to their inherent design and function. These transformers are typically used to separate different electrical systems, allowing for safe operation and maintenance without affecting the entire system. By isolating faults, they can prevent cascading failures or disturbances in the power supply, thereby enhancing the overall reliability of the electrical infrastructure.

Furthermore, isolating transformers help in improving equipment protection by reducing the effects of electrical noise and enhancing power quality. This is particularly beneficial for sensitive electronic equipment that requires stable voltage levels and minimal disturbances. As a result, the increased reliability is not just about the operational aspects but also about ensuring safety and protecting investments in both equipment and infrastructure.

Other choices may suggest advantages that could be context-dependent but do not directly relate to the primary benefits of isolating transformers in terms of enhancing reliability. For instance, while lower installation costs could be an attractive feature in some cases, it is not universally true for isolating transformers. Quicker maintenance might not always be applicable, as maintenance time can vary based on the specific setup and complexity of the system. Decreased load demand is not a benefit attributed to isolating transformers, as their primary role is not to control load but rather to provide isolation
