Medical areas are electrically divided into 3 classes based on standards. These are group 0, group 1 and group 2 rooms. Classification of a medical area is related with type of contact between sections related with the patient and the patient and purpose of use for the place.

Which class of rooms are IT Systems are applied?

IT Systems are implemented in Group 2 rooms those are medical areas where electrical supply interruption may cause a thread to life. Isolated power systems applied in accordance with IEC 60364-7-710 standards are used in group 2 rooms containing Operation Room, Intense Care, Anaesthesia Rooms, premature baby rooms where having vital importance and medical devices are directly connected to patients.

Which device and modules comprise Insulated Power Systems?

Insulated power systems consist of isolating transformer, insulation monitoring device, fault location system, alarm indicator medical changeover modules and auxiliary test equipments.

What are advantages of Insulated Power System?

• Personnel and patients are prevented from impacts of the electrical power.
• Insulation fault does not cause any power interruption.
• Fault current in the electrical system is reduced to non-critical levels.
• Continuity of power supply is maintained for medical areas.
• Electrical failure monitoring is guaranteed.
• Risk of fire caused by fault currents is eliminated.
• Electrical failure protection is maintained for expensive medical devices.
• Additional fault currents are collected and prevented from reaching critical values.
• Operation interruption is prevented.

How the Insulated Power System operates?

When insulation fault occurs, Insulated Power systems prevents an electrical problem through failure to defeat the system of power cuts make opening protection equipment, to continue its function of medical electrical equipment, fault currents to reduce non-critical value and the prevention of power outages.
Insulation level is continuously monitored in insulated power systems and converts the failure into an alarm signal by detecting at adjustable level not less than 50 kΩ. This alarm is monitored through two different alarm panels and are located in a section allowing control and intervention by the nurse or technical personnel in other rooms and through control panels in operation rooms. Alarm panels used for remote monitoring are located in Personnel On Duty room or technical service room.
In addition to the insulation level, transformer temperature and load current data are continuously monitored, immediately determined when nominal values are exceeded and alarm is given. No interruptions occur in the power supply. System continuity is maintained by preventing a second insulation failure that may occur in the system.
