Facilities that use an IT system for electrical distribution gain key advantages, especially in critical hospital environments such as operating rooms. These are its main contributions:
· High availability of electrical distribution: The IT system is the only option that guarantees service continuity in the event of an initial insulation failure. This makes it the best solution for ensuring that power distribution remains available at all times.
· Greater safety for people: This system is ideal for achieving high levels of safety, as it significantly limits earth leakage currents in the event of an insulation fault, reducing the risk of direct contact with exposed live parts.
· Lower risk of fire and explosion: Since the fault current is very low (from tens of mA to a few A), the risk of fire or explosion due to overheating or electric arcs caused by insulation faults is minimal.
· Protection of property and equipment: Unlike TT and TN systems, in an IT system the fault current during the first insulation fault remains at low levels, preventing damage to electrical loads and extending their service life. This helps to reduce repair costs and downtime, which would be higher in other earthing systems.
· Predictive maintenance: In ungrounded IT systems, an insulation monitoring device (IMD) is required to measure insulation resistance and detect any drop in performance. This allows intervention before the first fault occurs, facilitating efficient preventive maintenance.
The objective of these systems is to improve the quality of care, increase efficiency in healthcare processes, and reduce medical errors.
Our system offers an advanced solution for critical environments such as operating rooms or hospital technical areas:
Uninterrupted fault detection
Allows insulation faults to be located without stopping the installation, ensuring continuity of service.
Optimization of maintenance tasks
There is no need to disconnect the system to perform periodic checks, which reduces operating times and costs.
Continuous operation in the event of incidents
Even if a fault occurs, the system can continue to operate normally, avoiding unwanted downtime.
Greater safety for clinical staff
Thanks to reduced leakage currents, the risk of accidental electrical contact is minimized.
Reduced fire risk
Continuous monitoring of the insulation allows problems to be detected early, significantly reducing the risk of overheating or short circuits, which can even lead to savings on insurance.
