Medical Isolation Power Systems
IT Systems are distribution systems which are preferred less compared to Grounded Systems at Industrial Institutions however mandatory to use at Group-2 rooms in hospitals due to the electricity safety that is maintained in compliance to IEC 60364-7-710 Standard. The main difference that discriminates IT systems from Grounded Systems (TN or TT) is the non-presence of the Institution Grounding. This is obtained by isolation transformer and each load that is connected to this distribution system has its own individual grounding. These systems are mainly used in the supply of the hospital critical rooms like surgery, intensive care, premature childbirth, angiography examination rooms.

Benefits of the Isolation System;
- In the event of first isolation failure, energy blackout does not happen. The security equipment controls the system continuously therefore the energy blackout is prevented.
- The Medical Devices continue their normal operations.
- Fault Currents are reduced to non-critical levels which means the leakage current that is present within the room is reduced from mA levels to μA levels.
- A possible inconvenience in the surgery room is prevented where energy is reserved, and blackout does not happen.
