Toroidal transformers used in medical electrical equipment are different from those used in general instruments and have many special requirements.
1. Toroidal transformers used in medical electrical equipment shall prevent their basic insulation, auxiliary insulation and reinforced insulation from overheating in case of short circuit or overload of any output winding.
2. Protective devices that are external to the transformer or outside the transformer housing to prevent overheating, such as fuses, over-current releasers, thermal circuit breakers, etc., shall be connected so that the protective devices will not become ineffective when any components other than the wiring between the protective devices and the transformers are damaged.

The information of medical grade toroidal transformer:
What should be paid attention to in the design and production of power transformers for medical devices?
Insulation between primary and secondary transformers.Medical equipment are not used part of the protective earthing, and the application in the electrical connections, often require power transformer for the purpose of enhancing the insulation or double insulation dielectric strength, when the output voltage U 250 v or less, the pressure between the primary and secondary windings should be designed in more than 4000 v, when the output voltage 250 v ﹤ U 1000 v or less, at this point the pressure between the primary and secondary windings shall be designed in 2 (2 U + 1500 v) of the over voltage.
Short circuit and overload protection of power transformer.The primary winding of the power transformer should be protected by a safety device, which will automatically turn off power when the power transformer is overheated or overloaded during operation. In this way, energy efficiency can protect the power transformer and mechanical equipment.
