E-052 Unit Protection of Feeders: 3 PDH

Description of the Unit Protection of Feeders course

The Unit Protection of Feeders 3 hour PDH online course is a part of the Electrical category courses. The graded overcurrent protection design, though quite simple, do not meet all the protection demands of an electrical power system. Application issues are experienced for two reasons: firstly, acceptable grading cannot be accomplished for a complex electrical system, and secondly, the protection adjustments may lead to maximum operating times that are excessive and cannot stop faults.

These issues are directed to the unit protection concept. This concept means that parts of the electrical system are separately protected without reference to other parts of the electrical system. One unit protection concept is widely known as ‘Differential Protection’. Foundation of this principle is to detect the difference in currents between the incoming and outgoing terminals of the protected element. Other unit protection concepts can be based on directional comparison, distance tele-protection arrangements or phase comparison unit protection.

This course is suitable for electrical engineers with a desire to understand the fundamentals of feeder unit protection. Presented details cover basic unit protection concepts and their particular applications to high voltage feeders. Upon successful completion engineers will be able to address basic feeder unit protection terminology, concepts, applications and arrangements.
