Cable Fault Location, Part 1

SKU: TDCF100CENDuration: 60 Minutes

The purpose of this course is to teach the basic principles of using capacitive discharge equipment and voltage gradient equipment to locate faults in direct-buried cable. Examples are used to illustrate the considerations involved in locating faults. The use of capacitive discharge equipment to locate a fault in primary cable and the use of voltage gradient equipment to locate a fault in secondary cable are demonstrated. At the conclusion of this course, participants should be able to locate a fault in primary direct-buried cable using capacitive discharge equipment. They should also be able to locate a fault in secondary direct-buried cable using voltage gradient equipment.

Learning Objectives

  • Introduction to Cable Fault Location
  • Explain what a ground fault is.
  • List the essential components contained in fault-locating equipment for underground residential distribution (URD) cable.
  • Capacitor Discharge Test Unit
  • Identify and explain the purpose of the controls on a typical capacitor discharge test unit.
  • Explain how the high potential (hipot) test and the capacitor (cap) discharge test provide information that is used to determine the location of a fault in URD cable.
  • Locating a Fault in Primary URD Cable, Part 1
  • Perform the following preliminary steps before testing a primary URD cable: interpret the system diagram, ensure that the cable is dead so that it can be worked on, and connect the cables on a capacitor discharge test unit so that the unit can be used to test a section of cable in which a fault is suspected.
  • Locating a Fault in Primary URD Cable, Part 2
  • Describe how one type of pickup and detector arrangement can be used with a capacitor discharge test unit.
  • Pinpoint the location of a fault with the capacitor discharge test unit and the pickup and detector arrangement.
  • Voltage Gradient Equipment
  • Explain how voltage gradient equipment can be used to locate a fault in a section of secondary URD cable.
  • Identify and explain the purpose of the controls on a typical voltage gradient transmitter, pickup, and detector.
  • Locate a Fault in Secondary URD Cable
  • Perform the following preliminary steps before locating a fault in secondary URD cable: interpret the system diagram, ensure that the cable is dead so that it can be worked on, and connect the test leads on a voltage gradient transmitter so that a section of secondary URD cable can be tested.
  • Pinpoint the location of the fault using the voltage gradient pickup and detector arrangement.
