Testing & Commissioning

Introduction:

The "Start-up, Commissioning, and Testing of Electrical Systems" training seminar is meticulously designed to impart a comprehensive understanding of the principles underlying electrical installation and commissioning. Ensuring equipment readiness for commercial service involves rigorous testing of all its functions under varied conditions. The axiom 'Do not believe until it is proven' underscores the importance of thorough testing for the reliable operation of electrical systems. Equipment validation culminates in its energization and load testing during the start-up phase (initial energization).
Commissioning serves as a crucial stage where overlooked errors from earlier project phases are identified. Engineers, during testing, must handle both high and low voltages and currents. To mitigate risks of injuries and damages, it is imperative that they receive training to thoroughly comprehend the processes and meticulously plan every step of the commissioning procedure.
