Training Sessions
- Introduction to Cable Fault Location – 6 minutes Explains what a ground fault is. Lists the essential components contained in fault-locating equipment for URD cable.
- Capacitor Discharge Test Unit – 8 minutes Identifies and explains the purpose of the controls on a typical capacitor discharge test unit. Explains how each of the following tests provides information that is used to determine the location of a fault in URD cable: high potential (hipot) test and capacitor (cap) discharge test.
- Locating a Fault in Primary URD Cable, Part 1 – 9 minutes Explains how to 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 – 8 minutes Describes how one type of pickup and detector arrangement can be used with a capacitor discharge test unit. Pinpoints the location of a fault with the capacitor discharge test unit and the pickup and detector arrangement.
- Voltage Gradient Equipment – 8 minutes Explains how voltage gradient equipment can be used to locate a fault in a section of secondary URD cable. Identifies and explains the purpose of the controls on a typical voltage gradient transmitter, pickup, and detector.
- Locating a Fault in Secondary URD Cable – 10 minutes Describes how to 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 test leads on a voltage gradient transmitter so that a section of secondary URD cable can be tested. Pinpoints the location of a fault using the voltage gradient pickup and detector arrangement.
