         Course Description

Power plants and electrical utilities require a continuous highly stabilized power supply to ensure stable work conditions. To avoid potential risks in plants failure a stabilized UPS system is urgently needed in all power and factory utilities. The course is intended to develop knowledge of the need for a UPS, types available, UPS components, batteries, generators and maintenance.

Target Audience

  • Electrical Maintenance Engineer

  • Electrical Maintenance Foreman

  • Electrical Maintenance Senior Foreman

 

Course Objective:
