Hospital Isolation System and Operating Room Components
In hospitals—especially in operating rooms and critical care units—isolated power systems are used to prevent the risk of electric shock and electrocution. These systems ensure electrical safety by supplying isolated power through dedicated isolation equipment and accessories.
The isolated power system is one of the most vital parts of hospital infrastructure, as any malfunction could damage medical equipment or endanger human lives. Therefore, any failure in this system can result in both serious injury and financial loss.
To prevent such risks, Farad Tajhiz Sepanta Engineering Co. designs, manufactures, and assembles all components of the isolation system independently and with the highest quality standards.
The isolation panels are available in various power capacities and output configurations, according to customer requirements.
The hospital isolation system consists of several key components, each performing a specific function:
Isolation Panel, Ground Socket and Power Outlet, Central Grounding Unit, and Remote Alarm Units.
It is important to note that the isolation panel can also operate independently without other units if necessary.
Hospital Isolation Panel – Model 121
Isolation panels are installed in different hospital areas such as operating rooms, surgical preparation rooms, intensive care units, anesthesia rooms, cardiac catheterization labs, angiography suites, and neonatal intensive care units.
Each isolation panel generally includes two main parts: an isolation transformer and a Line Isolation Monitor (LIM).
The isolation transformer protects electrical circuits and equipment from electrical shocks and surges. It helps prevent equipment damage and protects operators from electrical hazards. Additionally, it filters out electrical noise and maintains ground isolation.
When equipment is powered through an isolation transformer, it becomes electrically separated from the ground. This means that if a technician accidentally touches a live component, they will not receive an electric shock.
In these systems, the input and output circuits are completely independent and isolated.
Isolation transformers are produced in single-phase, two-phase, and three-phase types, with various power ratings to suit different hospital needs.
The LIM (Line Isolation Monitor) continuously monitors the isolation level of the circuit. If a fault occurs, it measures the leakage current and—when it exceeds a defined threshold—activates an audible and visual alarm to alert the operator.
Remote Alarm Units
When a fault is detected in the isolation panel, the LIM sends a signal to the remote alarm units.
These devices notify hospital staff immediately, enabling them to take quick action to resolve the issue.
Remote alarms are typically installed in operating rooms and nursing stations for optimal visibility.
Ground Sockets and Electrical Outlets
Power outlets are generally available in two-gang or four-gang models, providing power to medical devices.
Each outlet includes a grounding (earth) system for safety, and ground sockets are used to connect the grounding system to medical devices in operating rooms.
Central Grounding Unit
Each operating room has a central grounding unit that connects the room’s grounding system to the hospital’s main grounding network.
The central unit then distributes the ground connection to all devices and outlets that require it, ensuring a reliable and continuous grounding path.
X-RAY Isolation System
The X-RAY isolation panel supplies power to portable radiology and imaging equipment in operating rooms.
It can be ordered in different power capacities and includes rotary switches with 4 to 8 positions for flexible operation.
X-RAY Outlet
The X-RAY outlet is used in various hospital areas such as operating rooms, orthopedic rooms, and delivery suites to connect radiology and imaging equipment.
Due to its special design and construction, it is capable of handling voltages up to 250V, ensuring safe and stable performance for diagnostic imaging devices.
