Reliability and safety you can depend on Vigilohm Insulation Monitoring Devices Hospital Marine Nuclear Vigilohm Your IT earthing system can be safe, reliable, and simple For automatic fault detection in IT earthing applications and manual fault location in sub-networks Continuity of service… in the event of an insulation fault Your operations cannot stop. Service interruption is just not an option. An IT earthing system allows your electrical distribution system to continually operate, even in the presence of an insulation fault, without endangering people or property. Required as part of an IT earthing system, an insulation monitoring device (IMD) detects the initial fault so you can make repairs before a second fault occurs which could trigger protective devices and halt operations. Even though IMDs are mandatory in IT earthing systems, not all IMDs are equivalent. When you choose an IT earthing system, you expect certain benefits – increased energy availability, improved safety, reduced risk of fire and explosion. Unfortunately, what you also expect from these systems and their components is complexity. Until now. Your IT earthing system can be safe, reliable, AND simple with Vigilohm Insulation Monitoring Devices from Schneider Electric™. 2 ‘When failure is just not an option, I know I can trust Vigilohm everytime.’ Proven reliability, features for today For more than 50 years, people have trusted the Vigilohm™ name for low-voltage IMDs for IT earthing applications. Vigilohm set the standard for IMD reliability, and now simplicity. The new Vigilohm IMDs for manual fault detection offer: The IMD detects the initial fault so you can make repairs > Simple ordering and operation > Universal installation options for easier and faster installation and connection > Synchronicity with modern, communicating ungrounded electrical distribution networks > Compliance with international standards for IT earthing systems > Harmonious integration into complete solutions > Exclusive measurement of leakage capacitance > Increased property life by enabling preventive and corrective maintenance operations Greatly reduce your risk of fire and explosions Many fires are started by intense, concentrated heating or by an electric arc from an insulation fault. The higher the fault current, the greater the risk. Whether on a ship, in a mine or on an oil rig, an IT earthing system can greatly reduce the risk of fire and explosions. A high fault current can result in significant damage to the installation, which would therefore require the cost and time for repairs. By having very limited fault currents, equipment is subjected to less stress and its life cycle is increased. A Vigilohm IMD injects DC or low-frequency AC voltage between the network and earth. The resulting current that flows through the IMD is then measured. The insulation value is calculated from this low-frequency current. 3 Vigilohm Flexible to fit the needs of Marine, Industry, and Energy & Infrastructure applications IEC Vigilohm IMDs comply within international product and safety standards: IEC 60364-4-41 IEC 61010-1 IEC 61557-8 IEC 61557-9 Simple, yet flexible Vigilohm IMDs fit the needs of specialized applications Vigilohm IMDs are flexible to fit the needs of many industries, including specialized applications like those in a hospital, where additional standards for safety and service continuity must be met. Choose from six Vigilohm IMDs for low-voltage monitoring applications where manual fault detection is desired. These IMDs meet international standards for IT earthing applications and differ in the size of network they monitor and some product features such as communications ability, alarm logging, and measured value display. All Vigilohm IMDs offer din rail and panel mounting options, and the Vigilohm IM10 and IM20 offer compatibility with both AC and DC electrical networks. Vigilohm IM9 Vigilohm IM9-OL IM9 is designed for small AC networks in marine and industrial environments. 4 IM9-OL is designed for insulation monitoring of offline motor applications in all earthing arrangements (TN, TT or IT networks). Features include motor start inhibition with a second threshold and the ability to authorize start even in case of low insulation. ‘When I install the IM10 or IM20 I know it’s compatible with both AC and DC networks. This gives me total confidence.’ Modern and communicating Vigilohm IMDs integrate into today’s modern and communicating ungrounded electrical distribution applications with communications abilities, alarming capability, and advanced monitoring functionality. A large, intuitive, graphical display supports language customization1 and makes data easy-to-read, even in low-light environments. The Vigilohm IMD indicates the fault on its display, and depending on the device: Only Schneider Electric displays the C value > Displays the insulation resistance value > Displays the leakage capacitance value for the monitored network > Stores time-stamped alarms > Communicates with a supervisor > Current injection inhibition to manage multiple, complex networks 1 Supports English, French, Spanish, Italian, German, Portuguese, Russian, and Chinese For Marine, Industry, and Energy & Infrastructure applications, choose either the Vigilohm IM10 or the Vigilohm IM20. These IMDs can be used in any ungrounded network application, except class 2 medical locations. DNV Featuring measurement and display of C Vigilohm IMDs are DNV Monitoring of C is essential on large networks since the C-related impedance can cause these networks to drift towards a TT arrangement, which would give rise to a dangerous contact voltage and a high fault current after an insulation fault. Only Schneider Electric displays the C value. Vigilohm IM10 (Det Norske Veritas) approved for safeguarding life, property, and the environment Vigilohm IM20 IM10 monitors both AC and DC networks and features a large graphical display. With the advantages of an IM10, the IM20 embeds advanced monitoring functions like: l l l l l Modbus communications capability and alarm log Display of leakage capacitance measurement Transformer monitoring (current and temperature) Current injection inhibition High-voltage sub-assembly compatibility 5 Helping ensure patient safety 6 ‘The advanced monitoring functions work perfectly in the operating theatre environment.’ Integration into a complete solution to address hospitals and class 2 medical environments IM10-H and IM20-H both comply with For maximum patient safety, hospital operating theatres require impeccable availability and quality of electric power. Vigilohm IMDs integrate seamlessly into the secure power distribution and monitoring solution for operating theatres from Schneider Electric. The Vigilohm IM10-H and IM20-H both comply with standards for use in medical locations and monitor network insulation. The IM10-H is a noncommunicating IMD for entry-range earth fault detection function, whereas the IM20-H offers Modbus communications capability and more advanced transformer monitoring functions. The Vigilohm Hospital Remote Panel provides the necessary audible and visual alarm to alert medical staff of an electrical fault. standards for use in medical locations: IEC 60364-7-10 IEC 61557-8 > Don’t compromise your expectations for an IT earthing system. Expand them. Remote Panel Hospital remote panel gives an audible and visual alarm in a hospital operating theatre. Vigilohm IM10-H IM10-H is a simple, noncommunicating product. Vigilohm IM20-H IM20-H embeds advanced monitoring functions including transformer monitoring, Modbus communications capability and an alarm log. 7 FREE!
