3 To optimise your electrical network For Power Distribution Utilities the market place is becoming increasingly competitive. There is a challenge to improve profitability whilst simultaneously providing higher quality. How can you address this paradox? in terms of safety, profitability, availability What does network automation provide? b Network management provides higher levels of service. b Having a major positive impact on both capital expenditure (CAPEX) and operational expenditure (OPEX), it allows you to face your market challenges in the best position. b Monitoring and control of your network follows your global policy of the electrical network equipment program such as retrofit, expansion, network equipment upgrade, operation (local or remote, manned or unmanned substation...), maintenance... One of your main needs to cut implementation and operating costs It is now known from market feedback that: b the MV distribution network has to face very frequent evolution - flexible solutions are mandatory b implementation duration may affect return on investment performance - the maximum has to be tested in factory b maintenance issue may be a difficult issue if not well addressed at the design level b the simplest may be the most efficient.

4 What are the expected benefits from Easergy range products? b Increasing customer service and satisfaction b Improving economic performance b Mastering investments (past and future). b Reduce outage time v Easergy Fault Passage Indicators identify certainly the network faulty section v Easergy control unit actuate network switchgear from remote control center. Customers satisfaction Margin effect Investment mastering b Optimised operation and use of the network v Easergy products provide accurate information on outages and significantly simplify and reduce the field crew effort required to clear faults v Easergy products dramatically reduce the time to localise faults and to re-configure the network v intelligent devices of Easergy products offer assume optimised maintenance procedure thanks to self test features and comprehensive maintenance function v Easergy products provide an efficient access to new communication system (GSM, Internet ). b Reduced pressure on budget by mastered costs and investments v Easergy modular and highly integrated devices reduces dramatically installation and commisioning costs v with Easergy offer, thanks to a comprehensive modular range, just invest what is really accessible and get immediate cash. Then proceed to relevant expansion when budget is available.

5 MV network Fault localisation Easergy-Flite Efficient range of Fault Passage Indicators for Overhead MV distribution lines b Designed for the tracking of permanent and transient fault on MV Overhead networks. b Thanks to ampmeter-di/dt and directionnal fault detection scheme it covers all type of MV networks. b Pole mounted or Clip-on line product assume the best fit with different lines arrangement. b Digital technology gives the lineman the facility to parameter in accordance with primary substation protection. b Connection to a SCADA system could be provided. b Advanced detection algorithm for an accurate Fault Passage Indication. b High visibility. b Long life duration thanks to lithium battery. Easergy-Flair Efficient range of Fault Passage Indicators for underground MV distribution networks b Designed for the tracking of permanent fault on MV cable networks. b Thanks to ampmeter and directionnal fault detection scheme it covers all type of MV networks. b A range of CT and power supplies assumes the best fit with all kind of substation configuration. b Digital technology gives the lineman the facility to parameter in accordance with primary substation protection. b Connection to a SCADA system could be provided. b Advanced detection algorithm for an accurate Fault Passage Indication. b Versatile and easy setting-up. b Long life duration thanks to lithium battery.
