PPO-Elektroniikka has delivered over 30,000 systems since 1983. The system is mandatory in all operating rooms in Finland. Nearly all operating rooms in Finland use our MEV-7 -system or its earlier generations.
MEV Insulation Monitoring System provides constant, safe, and secure monitoring of electrical systems in hospitals and other critical environments. MEV-units measure and control the power supply of IT systems. Units control either the insulation level of the IT system as well as the transformer load and temperature.
Our solution: MEV Insulation Monitoring System for hospitals
Absolute reliability of electrical systems is of vital importance in medical environments. Earth (grounding) leakages of electrical currents occur in new and old electrical devices alike. In the worst case, they can even cause the death of people around the defective equipment.
The monitoring of the aforementioned operating conditions is very important as invisible parts of the defective electrical equipment can cause seriously dangerous situations. Examples of such places and processes in hospitals are operating rooms, operating-preparation and post-operation premises, anaesthetic rooms, intensive care rooms, heart catheterisation premises, arteriographic/ angiographic rooms and preterm-babies care rooms.
If the preliminary conditions for the malfunctioning of the system begin to form in the electricity supply of the devices used in the aforementioned critical environments, MEV-7 immediately sets off an alarm, which prevents any accidents at a very early stage, thus saving money and even human lives.
Insulation Monitoring System is suitable also for other critical environments such as explosive sensitive EX-rooms, ammunition factories, chemical laboratories, production and service areas.
Reasons to use MEV - Insulation Monitoring System in critical environments
- The early detection of potential electric faults prevents risky situations during critical functions; for example during surgeries
- More efficient & effective usage of valuable surgical and/or other production equipment due to:
- predictable and timely maintenance which results in substantially smaller operating costs;
- reliable technology that allows an improved planning of operations as well as better organisation of work-shifts which results in an increased productivity of hospital staff
- Significantly increased lifetime of expensive surgical and/or production equipment.
Long before an electric fault occurs, MEV-7 notifies the personnel to preventively correct possible future insulation faults, such as malfunction of PE-wires and isolation transformers. Thus, insulation faults can be corrected well before they lead to a power failure because the personnel are alerted in due time before a critical incident occurs.
Due to the safety technology embedded in the MEV-7, complex and expensive equipment, as well as the people around it can be saved from harm and work more efficiently. In addition, the MEV allows the planning of fault repairs in advance to better suit maintenance purposes and clients’ needs.
MEV Insulation Monitoring System - absolute reliability
MEV-7 –type insulation monitoring systems are required in operating rooms and similar Class II medical premises in all countries in the European Union due to the EU regulation.
Leakages of electrical currents occur in new and old electrical devices alike. During a surgery such leakages in the operating and other equipment can be dangerous both for the patient and the personnel who performs the surgical procedures.
Our solution is to separate the equipment of the operating room from the main power system with an isolation transformer. MEV-7 monitors the electrical devices connected after that transformer. Our systems, which are especially developed for use in healthcare facilities and operating rooms in hospitals, include high-reliability isolation transformers and are internationally approved by medical authorities.
The fifth generation MEV-8
We have developed our fifth generation in cooperation with hospital engineers. Our MEV-8 meets all the regulatory acts and technical standards in Europe and in the Nordic countries. MEV-8 is also suitable for critical environments in industrial field.
MEV-8 line isolation monitoring relay measures leakage current from floating isolated AC system to ground. MEV-
8 also monitor measurement wires and transformer load / temperature. Alarms are indicated via LED lights and relay contacts. MEV- 8 operates 230Vac, 50/60Hz.
