Training UPS Systems Operations and Maintenance

Training UPS Systems Operations and Maintenance

INTRODUCTION

Supplying reliable electric power for critical systems is an essential part of modern industrial installations. Electrical engineers in any industry or other large facilities in diverse areas such as commercial buildings, transportation systems such as railways, airports etc. are bound to come across AC or DC uninterrupted power supply systems. In this course, participants will learn about various options of UPS systems, the principle of operation and the main energy source in most of the modern UPS installations, the battery, and their importance.
