Introduction

Power system equipment must withstand not only its rated voltage but also short circuit voltages. A key issue related to voltages is arc flashing, which primarily relies on short circuit and relay coordination studies. ETAP (Electrical Transient Analysis Program) is a widely used software for power system analysis in various industries. This training course focuses on power system modeling and analysis using ETAP software to assess different power analysis models.
