Power Supply for Protection & Control Systems

Introduction:

The objective of this course is to stress the importance of uninterruptible power supplies for protection and control circuits, and to look at different means of achieving this. The provision of both continuous AC and continuous DC power supply is discussed and attention is paid to individual power supplies for electronic equipment. Some time is devoted to studying operation and maintenance of the common storage battery. This area often seems to be neglected, even though it is after all, the heart of uninterruptible power supplies.

Course Objectives:

By the end of this course delegates will be able to:

Understand the meaning of lead acid cell, lead antimony and lead calcium
Know the different voltage level requirements
Develop and understanding of the significance of specific gravity and output voltage per cell
Understand the meaning of sulfating
Know and apply safety precautions against acid
Gain a thorough understanding of Charger adjustments: float voltage, equalization voltage, programmed equalization, output slope, and current limiter
Learn about the controlled ferroresonant battery charger
Discover the advantages and the need for off-line UPS system and on-line UPS system and the triport UPS system
Learn about the importance of shield connecting leads
Gain knowledge of the filter capacitor usage and its features
Understand the need for "reliable" continuous power supplies to operate protection and control relays and circuits
