Transformer Energization Study

  • Software
    EMTP RV software is used for Transformer Energization Studies
  • Codes & Standards
    CIGRE C4.307 Transformer Energization in Power System
  • Methodology
    EMTP RV Modelling is used to simulate multiple Switching operations of the CB. Scenarios to be considered: Varying the Switching time of phase of the breakers, Varying the transformer residual flux, Minimal and Maximum possible values of SC at PCC, With and Without other already connected transformers.
  • Analysis
    Study and Analyze the voltage related problems (RMS Voltage Drop & TOV) created by inrush currents during transformer energization. Study & Analyze the primary side profile of THD due to Inrush Current with Rich Harmonics
