    1. Much more than protection REX 521 Feeder Protection Relay and KEVCD Sensor Technology

    2. Improve the network... The REX 521 combined with the KEVCD Sensors will improve your network with beneficial extra features

    3. Content 1. A solution with no saturation 2. Ensures accuracy at high current 3. Gives savings in engineering time 4. Results in savings in material and work 5. Ensures improvements in human safety -accuracy at high current enables measurements of real short circuit values. - linear temperature reduces the need for cooling aggregates in the swithcgear. Operating range is xxx -xxx-accuracy at high current enables measurements of real short circuit values. - linear temperature reduces the need for cooling aggregates in the swithcgear. Operating range is xxx -xxx

    4. Solution with no saturation

    5. Solution with no saturation

    6. Improved Accuracy

    7. Less engineering With sensors you can considerably save engineering time and improve your efficiency

    8. Improve efficiency No need for neither AFL nor burden calculations. Only a few types of sensors are needed. Cables are included in the delivery

    9. Savings in project lead times Universal and standardised sensor types reduce the need for detailed planning and therefore, can shorten project delivery times!

    10. Savings in material and installation With sensors you can save material costs and reduce the risk of possible human errors!

    11. Secondary wiring, the conventional way - maximum length for cabling is 10 meters. - 5, 6.5, 7.5 meter standard cable length. - in practice the secondary wiring is removed. Let’s have a look on what is needed for CTs and VTs.- maximum length for cabling is 10 meters. - 5, 6.5, 7.5 meter standard cable length. - in practice the secondary wiring is removed. Let’s have a look on what is needed for CTs and VTs.

    12. Savings in material and installation Mounting equipment needed for CTs: - 3 Current Transformer - 14 Terminal blocks - 4 Bundles ( 26 cables) - mounting material - calculations based on typical swithcgear- calculations based on typical swithcgear

    13. Savings in material and installation Mounting equipment needed for VTs: - 3 Voltage Transformers - 18 Terminal blocks - 5 Bundles ( 26 cables) - Ferro resonance resistor - mounting material - calculations based on typical swithcgear- calculations based on typical swithcgear

    14. All you need with sensors is... - maximum length for cabling is 10 meters. - 5, 6.5, 7.5 meter standard cable length, are standard parts of the delivery. - in practice the secondary wiring is removed. Let’s have a look on what is needed for CTs and VTs.- maximum length for cabling is 10 meters. - 5, 6.5, 7.5 meter standard cable length, are standard parts of the delivery. - in practice the secondary wiring is removed. Let’s have a look on what is needed for CTs and VTs.

    15. Savings in material and installation... Improve efficiency through savings in material cost, installation time and shortened project lead times ! - calculations based on typical swithcgear- calculations based on typical swithcgear

    16. Personal safety during installation Improve the safety of your personnel With sensors you reduce the risk of short circuits in the switchgear during installation and maintenance Jännitetaso 150mV, max 10VJännitetaso 150mV, max 10V

    17. Local presence We are wherever You are!

    18. Delivery and Support Local presence in over 40 countries provides you with timely and reliable support whenever needed

    19. Ordering Clear specifications for ordering will make it easy for you to always find the right solution

    20. Ordering When ordering REX 521 protection relays, specify the following: • Order number • Quantity • Additional language

    21. Ordering Very easy and simple ordering …

    22. Conclusion - Improve efficiency through fast engineering and prevent accidents from happening - Implementation time is reduced thanks to easy installation - Personal safety is ensured - Engineering time is reduced thanks to standardised solutions - Timely and local support is at your service - Ordering is easy

    23. In a nutshell... You do not only get operational reliability…
