LIFE SAVING TECHNALOGY- INSULATION MONITORING SYSTEM
ABOUT US
Authorised Distributor Of PPO Elektroniikka, Finland for India
MEV® Insulation Monitoring System:
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.
WHY IMD SYSTEM
- The early detection of potential electric faults prevents risky situations during critical functions; for example, during surgeries.
- 24 x 7 monitoring of electrical equipment in OT, ICU & Emergency ward which could endanger patients.
- Predictable and timely maintenance which results in substantially smaller operating costs.
- Significantly increased the lifetime of expensive surgical and/or production equipment.
- Improved operations planning as well as better organization of work-shifts which results in increased productivity of hospital staff.
- More efficient & effective usage of valuable surgical and/or other production equipment due to.
- Protect from unexpected electrical Short Circuit and resulted in fire in hospitals.
- Generate & display the alarm to authorized person in emergency situation.
- No entire circuit interruption due to failure an individual equipment.
- Centralize supervision of electrical equipment in ICU/Emergency ward OT.
- Permanent protection provided to the staff & patient.
- Empower staff to easily diagnose issues.
Demonstration of MEV-8 System
MEDICAL ISOLATION POWER SUPPLY SYSTEM:
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.
IMD PRODUCT DETAILS
INSULATION LEVEL MONITORING DEVICE MEV-8
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.
- 500 V Measurement of insulation resistance is forbidden in circuits monitored by MEV-8!
- Insulation level monitoring.
- Transformer load monitoring (requires a current transformer and a shunt).
- Transformer temperature monitoring, 10K NTC or PT100 thermistor.
- Three voltage-free SPDT relay contacts for alarms.
- The LED lights indicate pre-alarms, alarms and the alarm memory.
- RS-485 bus for communication between modules.
LC-8 LINE CONTROLLER
- LC-8 Line controller monitors the continuity of a floating IT network’s protective earth.
- If protective earth is interrupted at the line that is being monitored, the green LED light [1–6] of the LC-8 channel goes out and the red LED light turns on. MEV-8 PE/LC-8 [OK] LED light [green] goes out and [Ground] LED light [red] TURNS ON.
- In a normal state, green lights [1–6] indicate the protective earth continuity of the channels in use.
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.
FAULT LOCATOR UNIT FI-8
- FI-8 fault locator device locates any insulation faults in a floating IT network.
- In a normal state, the green light indicates that the panel is on and connected to an MEV-8 insulation level monitoring device, and the red LED lights [CH1–6] are off.
- An insulation fault is indicated by a channel-specific red LED light [CH1–6], the MEV-8 MONITOR PC program and SP-8 panel.
- After the fault is cleared, the red LED light goes out.
- Installation on a DIN-TS35 rail.
- The address (2–26) is set with DIP switches. The address number 1 is reserved for MEV-8 device.
- Supply voltage 12 VDC (through data cables).
SP-8 SYSTEM MONITORING PANEL
- The SP-8 System monitoring panel indicates any insulation level alarms, line controller alarms and test wire faults as well as transformer overload and temperature alarms.
- In a normal state, the green light indicates that the panel is on and connected to an MEV-8 insulation level monitoring device. The display indicates the current insulation level, transformer load and temperature.
- An insulation level alarm is indicated by a yellow [Insulation] LED light and a buzzer, and any line controller and test wire faults are indicated by a red LED light [Pe/Wire] and a buzzer. The buzzer can be reset with the [Mute/Reset] button. Alarms are also indicated on display.
- A transformer overload is indicated by a red [Overload] LED light and a buzzer. A temperature alarm is indicated by a red [Temp] LED light and a buzzer. The buzzer can be reset with the [Mute/Reset] button.
- When the fault is cleared, the SP-8 will reset automatically.
AG-8 ALARM GATEWAY FOR ALARM COMMUNICATION MODBUS (RS-485)
ALARM GATEWAY AG-8 UNIT TRANSMITS ALARMS TO TOUCH-SCREEN PANELS AND THE CONTROL ROOM’S PC PROGRAMMES
VIA THE MODBUS (RS-485).
- AG-8 alarm gateway unit transmits MEV-8 system alarms to touch-screen panels and the control room’s PC programs via the rs-485 bus.
- The device has additional opto-isolated input for alarm status reporting. For example MCB trip monitoring purpose.
- Installed to the DIN TS35 rail in the distribution board in the monitored space.
- The address (1–64) is set with DIP switches.
- Supply voltage 12 VDC (through data cables).
ISOLATION MEDICALE TRANSFORMER
MEDICAL ISOLATION TRANSFORMER IS THE MAIN COMPONENT OF MEDICAL ISOLATION POWER SUPPLY.
Key Performance:-
- Double Insulation, Quiet Design, Meet 4200V/ Min Dielectric Strength Test.
- H Grade Insulation Material, Allowing Higher Temperature Rise, Longer Service Life.
- PT100 Temperature Sensor Is Built Into The Wire Package.
- Impulse Current (IE) : <12in (Actually Close To 8 Times The Peak Of Input Current).
Note:
- 3 Ph transformer not allow to supply power to 1 Ph & 3 Ph medical equipment directly
- 3 Ph transformer line voltage shall not exceed 250V;
- 3 Ph loads in medical places are basically insignificant loads.
