Isolation Transformers

Transformers can be more than just static devices that transfer electrical energy. Separation transformers, isolation and extra isolation transformer play a major role in the protection of people and equipment. They come in all ranges, from very small (a few VA) to quite large (a few MVA), and although more expensive than autotransformers or transformers with simple separate windings, they are an easy way to solve problems that could arise concerning:

• Protecting individuals from electrical shock
• Avoiding losing power in the case of a first insulation fault
• Protecting sensitive equipment from electrical noise
• Creating a star point for equipment that require it
