Course description and overview
CABLE FAULT LOCATION & TRACING, MEDIUM-VOLTAGE (CFLT | #132) 4.5 DAYS | 3.2 CEUs
This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot 5-35 kV solid dielectric power cables. Medium voltage cable systems are the backbone of electrical systems worldwide, yet they are often the most ignored part of the power system – until there is a failure. One of the most important aspects of medium voltage cable maintenance is “fault location.”
Cable systems today have higher failure rates than ever before, due to aging, environmental stresses and improper installation. The ability to efficiently locate faults, greatly reduces downtime and outage costs.
Learning objectives
Upon completion of this course and lab, the participants will demonstrate by attaining a minimum average grade of 80% (between lab practice and final exam), that he/she is able to:
- Identify medium voltage cable components and causesof failure.
- Utilize safe work practices for cable testing per OSHA and industry consensus standards.
- Trace cable installations with modern cable route tracing and identification equipment.
- Locate secondary faults using earth gradient (sheath fault) technologies.
- Pinpoint faults using magnetic and acoustical tracing system and arc reflection technologies.
- Apply a proven fault locating process; Test, Analyze, Localize.
- Locate faults in a comprehensive cable field lab environment.
