Course Overview

Introduction:

Vacuum Circuit Breakers (VCB) are the leading technology in the Medium Voltage Networks (Utilities and Industries). VCB are not only economically feasible but also offers many technical advantages over its competitor technologies. Since, there are many international and local manufacturers present in market, advertising their products. It is the duty of the procurement/end user engineer to ensure that VCB selected is properly rated and the features required are selected according to the requirements. Once rightly designed or selected VCB could save a lot of losses and unwanted outages throughout its service period. Similarly, for project engineers it is extremely important that MV/VCB Switchgear is installed properly and during commissioning all the tests have been developed properly as per International Standards to provide base line for further testing and results comparisons and health analysis of switchgear. Also, for Operation & Maintenance Engineers, they should be aware about basic theory, parameters, correct maintenance procedures, hazards & how to eliminate them during involving the operation and maintenance. This course is targeted to cover parameters and their impacts to installation, commissioning and maintenance engineers.

Course Contents:

This course is intended to familiarize the attendees with following topics.

• Basic Theory & Concepts
• Various Parameters of VCB and their impacts on performance
• Requirements and basic criteria’s of Type test of VCB
• Factory Acceptance Testing (FAT)
• Installation & Commissioning
• Testing & Maintenance Techniques
• Hazards in Operations and their counter measures

Course Objectives:

• This course intended to familiarize the attendees with basic concepts of VCB technology.
• This course intended to familiarize engineers about the basics of testing (Type tests & FAT).
• This course intended to familiarize the engineers about the selection/design criteria and their impacts on the performance, maintenance, reliability and life cycle of the VCBs throughout their life.
• The course intended to familiarize the engineers about the correct installation and commissioning procedures and common mistakes done in the procedure.
• The course intended to familiarize the engineers about the maintenance procedures and what exactly to look and how to interpret test results and detects faults before they translate to faults and tripping.
• The course intended to familiarize the engineers about the correct operating procedures, hazards and their corrective actions.
