International Consortium of Investigative Journalists in 2019:
“Manufacturers, doctors, and others potentially linked more than 1.7 million injuries and nearly 83,000 deaths to medical devices in reports to U.S. regulators over the last decade.” Insulation monitoring is one of the most efficient measures to prevent dangerous situations.
MEV-insulation monitoring system has saved lives and protected valuable equipment in worldwide hospitals since 1982.
The electrical current leakage is a real danger to the staff and patients; it can cause a fatal electric shock without any visible signs. Now a day the system is mandatory in all operating rooms in EU country & many other. No operation will be performed in operating rooms if insulation monitoring is not in use. All hospital districts in Finland use the MEV-8 insulation monitoring system or MEV-7 system or earlier generations.
Our fifth-generation MEV-8 has been in production since 2020. PPO has developed MEV-8 in cooperation with hospital engineers – the new-generation equipment meets all international regulatory acts and technical standards.
The Medical Isolation Power System Which Transfers the Grounded System (TN-S System) To the Ungrounded System (IT System) By Using “Isolation Transformer” Which Power-Up Important Medical Equipment.
The insulation monitoring device is designed to monitor the insulation resistance of single-phase ungrounded systems in healthcare. The insulation monitoring device enables monitoring of ungrounded IT power supply system’s up to a maximum operating voltage of 264 V AC. It can also evaluate thermal and current overloading of the isolation transformer.
IMD system mainly consist of the Isolation Transformer, Insulation Monitoring Device, Fault Locator, Signal Test & Alarm & Display Device.
The MEV-8 insulation level monitoring device monitors the insulation of a floating IT network (leakage current), transformer load (current A or percent %) and temperature (°C). Insulation faults can be located with an FI-8 fault locator unit. The continuity of protective earth is monitored with an LC-8 line controller. Alarms are indicated by monitoring panels (EV-8, M-8 and SP-8). Alarms are also indicated with relay outputs. MEV-8 also detects capacitive faults.
Note: After the technical measurements of the electrical network (the resistance of the protective earth has been found to be less than 0.2 Ω), the reference is set with the [REF.] MEV8 MONITOR program. Periodic protective earth wire continuity testing will be performed against this stored reference.
