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
