INTRODUCTION:

 

Although cables are built to last, faults remain inevitable due to excessive moisture, corrosive environments, overheating, and aging. This course will help customers learn how to operate a wide range of cable fault locators

Cable systems are the backbone of electrical systems worldwide, yet often they are the most ignored part of the power system until there is a failure. Cable systems today have higher failure rates than ever before due to aging, environmental stresses and improper installation. While the ability to efficiently locate faults can greatly reduce downtime, an effective cable testing program can help technicians prioritize cable repair prior to failure. This helps prevent unplanned outages, equipment damage and electrical accidents.

OBJECTIVES:

 

At the end of the course participants will able:

  • Identify medium voltage cable components and causes of failure
  • Isolate faulted sections using advanced sectionalizing techniques
  • Utilize safe work practices for cable testing and industry consensus standards
  • Minimize supply disruption by locating cable faults more quickly
  • Reduce expenditure by accurately locating faults first time avoiding multiple excavations
  • Develop an understanding of the interaction between power system elements
  • Gain expertise in using the latest power cable fault detection equipment
  • Update your knowledge of the latest techniques and technology
