Isolating transformers can be used:
- When galvanic isolation of the load and the user from the power source (e.g. power grid) is required for protective purposes. The supply voltage can be transformed to a different value at the same time
- When there is a need to supply large loads, such as in industry or shipping
- When the transformer is incorporated as a component of a circuit/configuration (e.g. electrical control panel)
Safety isolating transformers can be used:
- When safe extra low voltage (SELV) is required, in addition to isolation
- In auxiliary automation circuit power supply, when a high level of safety is required in handling
- When the transformer is incorporated as a component of a circuit/configuration (e.g. electrical control panel)
