METI / ECCJ / ACE Training Program MTPEC06 (2007.01)

(6) Electricity
1) Points of Energy Conservation on Electricity
  1. Power receiving / transformer / distribution equipment
    Power consumption = [Transformer loss + Distribution loss
    + Load] ×Operation Time (kWh)
    1. Lowering of transformer loss Adequate capacity, high efficiency,
      number control in operation, etc.
    2. Distribution loss (Shorter wiring, larger wiring)
  2. Motor
    High efficiency, high power factor, inverter, etc.
  3. Lighting
    1. Application of high efficiency lamp, etc
  4. Electric heating equipment
(6) Electricity
2) Motor Efficiency
Target efficiency for high-efficient totally enclosed motors (0.2～160kW)
(6) Electricity
Target efficiency for high-efficient protected motors (0.75～160kW)
(6) Electricity
3) Comparison of Motor efficiency
