4 Toekomst Begin stand Wie gelooft dat een toekomst heeft? Wordt binnen 5 jaar dagelijkse activiteit? Gaat AC in het laagspanningsnet vervangen?

5 AC had gewonnen Geschiedenis AC has won has lost 1880 Battle between Tesla and Edison War of currents

6 AC doodlopend Problemen in AC en is AC een winnaar? Er is geen standaard!!! Slimme netten - hoe maak je een dom systeem slim? Verandering kan goedkoper zijn China

7 Hoe Strategie We hebben een super plan: We hebben een oplossing voor: Niet bestaand probleem Niet bestaande klanten Niet bestaande vraag Dit is een zéér strak plan

8 HOE Hoe doen we het Visie Functies en AC problemen voeden ons plan Opleidin g Netwer k Politie k masterplan Groot denken Dramme n Lef R&D

9 oplossing Waar gaat het om Opwekken Besparen Maar belangrijker is de -Verbinding- Gelijkspanning is daarom het fundament onder duurzaamheid

22 Standards Issues found TC64 (NEN1010) AC hand writing and AC glasses textual issues Phase and Pole (need in chapter 7 a additional sub chapter redefinition in terms). M and N (neutral) mismatch. Connected means that current can flow for example a Neutral PE connection. Warning about corrosion in grounded systems is noted Mechanical disconnect (can become a conflict) Wire color not clear yet (but close to be defined) Safe voltage is only safe when power is limited. 120Vdc or 60Vdc Conclusion A Guideline is needed to help to understand systems Examples of installations All cables can be used (but must be mentioned in the datasheet) Discussion left about separation Mechanical versus Converter But the NEC 64 is well written and we don t expect big issues for that can block systems

23 in practice What does this mean for installers Tools for detecting voltage not depending on AC or Discussion (Light conducting shoes) Knowledge!!!!!! (Training becomes a must) Proper marking and labeling of cables or connection High attention in hybrid systems (AC and combined) We like to see a stronger definition of certification where people can work (not based on voltage but also based on energy level).
