Calculation of Insulation

  • Vasily Y. Ushakov
Part of the Power Systems book series (POWSYS)


One of the main characteristics of insulation of high-voltage systems is the permissible working field strength. The permissible field strength is chosen based on static, voltage—time, and statistical characteristics. In Part 2, the experimental results were presented that mainly concerned the first two characteristics. In Chapter 11, methods for calculating these characteristics for various dielectric media are summarized, the statistical nature of breakdowns (the distribution function of U br) is analyzed, the necessity of its consideration in calculation and coordination of HES insulation is demonstrated, and methods for calculating the operating lifetime and reliability of insulation are also considered.
