2 For a high level of operational and electrical system safety: Unearthed power supply systems (IT systems) Modern power supplies require maximum availability, safety and predictive information A wide variety of production processes, continuous competitive pressure, the impact of soaring costs and operational availability around the clock requires maximum possible electrical safety for power supplies. Although great care has been taken in the design, during implementation and maintenance: electrical installations may nevertheless be impaired by moisture, ageing, dirt or mechanical damage and errors cannot be entirely excluded. Undetected insulation faults, however, can prove to be disastrous and may involve more or less high costs, e.g. caused by production failure, repairs, device replacement or even unplanned service work. The objective: reducing costs increasing availability The key objective of any user must be, to recognise faults at an early stage and to eliminate the cause of faults in an efficient way in order to achieve the best possible operational and system safety and in the long run to reduce costs drastically. Possible solution Unearthed power supplies (IT systems) with insulation monitoring. In unearthed power supplies (IT systems), there is no active conductor directly connected to earth. On the occurrence of an insulation fault, therefore, only a small leakage current, essentially caused by system leakage capacitances, can flow. The upstream fuse does not trip, hence continuous power supply and operation is ensured. Prompt information about possible hazards is given by the A-ISOMETER which continuously monitors the insulation resistance between system and earth. A-ISOMETER : A wide variety of solutions for all types of IT systems For the whole range of electrical power supply, Bender provides appropriate solutions for most varied applications. Taking all types of system structures and loads into account, A-ISOMETER s using the patented measuring principle guarantee reliable evaluation of the insulation resistance for Nominal system voltages AC, DC or AC/DC up to 7.2 kv System configurations 1ph, 3ph, disconnected loads System leakage capacitances up to 500 μf Response values from 1 kω to 10 MΩ Advance information thanks to the A-ISOMETER Principle of operation A-ISOMETER 2

3 IT systems for up-to-date information A-ISOMETER in unearthed power supply systems (IT systems) provide effective damage prevention, increased productivity, optimized maintenance and considerable cost reduction. Bender's wide range of products allows the implementation of individual safety solutions and hence ensure the security of investment. Increased economic efficiency Avoiding expensive and unplanned system downtimes Reducing personnel and time-intensive maintenance Recognising weak points in the electrical installation Supporting investment management High operational availabilty No interruption to operation in the event of a phase-to-earth fault No control malfunction in the event of insulation faults Electrical installations are kept at a high level of availability Off-line monitoring of electrical installations is also possible Optimised maintenance Recognising and signalling insulation deterioration at an early stage Localising faulty circuits automatically Optimising the planning of time and personnel recources Displaying information about the status of the electrical installation at a central location Remote diagnosis via Internet/Ethernet Increased protection against fire Recognising gradually developing insulation faults at an early stage Minimising arcing faults, a frequent cause of fire Separating areas subject to explosion and fire hazards from the rest of the system by means of isolating transformers and monitoring them Enhanced accident prevention Low touch currents in small and medium-sized installations No malfunctions in case of earth faults in control circuits of equipment and machines Higher permissible earthing resistance Higher earthing resistances, permissible, for example, for mobile power supplies 3

4 Control and auxiliary circuits Control and auxiliary circuits are used for additional functions, such as command output, interlocking, alarm and measuring circuits. For these circuits particular emphasis is placed on operational reliability. Control circuits, such as machine control systems or safety lighting, are limited in space.

6 Main circuits Main circuits provide power supply for electrical installations or buildings. These circuits include equipment for generating, converting, distributing, switching and consuming of electrical energy. From the user's point of view, different types of loads are to be distinguished: pure AC loads (e.g. motors), AC/DC loads containing electronic components (e.g. converters) and pure DC loads (e.g. battery systems).

12 EDS Insulation fault location system The special extra for increasing the reliability of your electrical installation In order to achieve high availability and to avoid costly shut-down periods, it is necessary to recognise insulation faults at an early stage - before interruption to operation occurs. For this reason, unearthed systems (IT systems) with insulation monitoring are used for the power supply of essential electrical installations and loads. The A-ISOMETER provides the necessary advance information. Fast localisation and elimination of insulation faults is required by DIN VDE (VDE ): Section The IRDH575 in combination with the EDS system is a modular system ideally suited for this task. There is a wide variety of application fields for EDS systems. They are used for: Main circuits and control circuits Advantages of the EDS insulation fault location system Disconnection of the electrical installation is not required, insulation fault location during operation Fast localisation of faulty circuits Provides fault location information at a central point Suitable for utilisation with EDS3090/3090PG and EDS3091/3091PG Reduced maintenance and reapir costs Examples of application: Power plants Hospitals Shipbuilding Traffic engineering Industrial installations Paper industry Oil and natural gas industry Mining, open-cast mining Rolling mills Mechanical engineering and in a lot of other sectors. 12 Example of application

16 Bender monitoring systems boundlessly communicative Modern communication Due to the fact that increasing demands are placed on communication capability, data transparency and flexibility, the use of modern fieldbus and network technologies has become a must. Hence, operating, warning and fault messages via the web or network, for example, contribute to increasing the transparency of power supply systems, allowing a fast reaction to citical operating states. In addition, important messages can be transferred via short message service or s to mobile phones or laptops of the service personnel. Early information about location and the cause of fault allow time and cost-efficient deployment of service personnel and can avoid equipment failure or the damage of expensive devices. Electrical Safety Management Embraced by the term Electrical Safety Management Bender provides coherent solutions for the electrical safety of power supplies in all areas. Carefully matched products and systems with innovative measuring techniques, communication solutions for the visualisation of data from Bender monitoring systems as well as easy connection to fieldbus systems and to Building Control and Central Building Process Control Systems prrovide the maximum possible safety, economic efficiency and transparency. The range of products is completed by comprehensive services beginning with planning and advisory service extending through the whole service life of the products. 16
