Abstract
 Plastic products factory enterprises used for distribution, which can meet the needs of production, distribution systems make for a safe, reliable, economic and reasonable operation is before us of the urgent need to solve new problems. Based on the 10 kV line into plastic products factory for the distribution characteristics of enterprises, on the 10 kV line into plastic products factory enterprises within the main power supply, and gain a more detailed analysis. The whole plant to calculate the total load group, all members of the plant load calculation and reactive power compensation to develop the capacity of transformers, Taiwan and several models to calculate the active, reactive and apparent power, power factor completed, the completion of the main electrical Diagram of the design, conduct further short-circuit current calculation, the completion of cable wires and a selection of the model calibration, high-pressure equipment to complete the selection, a relay coordination, the sensitivity of the test, mine and the grounding of the design
