Sites (Poland)• Two utilities in Poland are the candidates:
– Wrocław (potential link to building rewiring campaign)
– Łódź
Both are supporters of energy efficiency policy
• 3 to 4 installations 100 – 630 kVA per site

Super Trafo 2001
Transformer selection• Load profile matching
• Above CC’ (HD 428) level
• The lowest cumulated costs of transformation as the main criteria
• Purchase costs
• No load and load losses during lifecycle time (including new capacity avoidance)
00-10-23 Moje dokumenty/ECI/Prezentacje/supertrafo 12
Super Trafo 2001
Metering• Continuous power, cos Ф, no load and load
losses calculated (model and factory data) or measured ( directly by two –in and out - energy counters or indirectly by Uin, Iin and oil temperature measurement)
• Comparing the actual losses with replaced trafo losses computation saving
