Online Training – Sistem Proteksi Tenaga Listrik



  • It introduces the subject of protection as an art where technical and economical constraints are to be met and compromised to achieve certain engineering requirements.
  • Learn to develop and manage well-protected plants that lead to a higher security, less outages and hence better profitability.
  • The course introduces new technologies used in relaying systems such as microprocessor and computer relaying which put organizations at the forefront of modern electricity industries.
  • Helps organizations in making appropriate decisions at times of system expansion or in situations where new developments become necessary
  • Help organizations to understand causes of system failures, means available for remedies and hence better system management and operation with minimum investment.
