Electrical cable training

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.

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.

CABLE SPLICING AND TERMINATING, MEDIUM-VOLTAGE (CSTMV | #130)
4.5 DAYS | 3.2 CEUs

This course provides instruction on the proper installation of cable splices and terminations. New or experienced electricians and technicians that install, maintain, repair or troubleshoot 5-35 kV solid dielectric power cables will benefit from this course. Properly trained and skilled craftsmen, who install and test the cable correctly, can drastically improve the life expectancy of cables.

According to IEEE Std. 493-2007, Table 10.33, inadequate installation and testing prior to start-up of cable splices and terminations are the primary causes of failure. Yet over the last few decades, cable splicing and testing as a profession has declined. Multi-crafting and departmental mergers have made it just one task among many.

To receive 3.2 CEUs, the participant must attend 4.5 days of class (32 contact hours) and attain a minimum average grade of 80% (overall grade will consist of 50% final exam). 

Upon completion of this course and lab practice, the participant will demonstrate that he/she is able to:

• Explain medium voltage cable components and construction.
• Identify applications of different cable types including marine, offshore, mining, underground (URD) and tech.
• Prepare cable for splicing utilizing hand tools, abrasives and solvents.
• Install taped, molded and heat shrink splices on tape-shielded and jacketed concentric (JCN) cables.
• Install taped, cold shrink, heat shrink and molded elbow terminations.
• Utilize a high potential tester for performing withstand tests on assembled splices.
• Identify the causes of splice and termination failures.
• Explain procedures for buried, duct and tray installation and relevant OSHA safety requirements.

CABLE TESTING & DIAGNOSTICS, MEDIUM-VOLTAGE (CTDMV | #131)
4.5 DAYS | 3.2 CEUs

This comprehensive hands-on preventative maintenance course is intended for engineers, electrical technicians, and supervisors that test, install, maintain, repair or troubleshoot 5-35 kV solid dielectric and paper insulated power cables. Students will perform and analyze results of insulation resistance tests (DAR & PI), type I withstand tests (DC, AC, & VLF). Also, diagnostic test such as Partial Discharge and Tan Delta will be performed. Cable Diagnosis is predictive and is often performed as part of condition-based maintenance strategies. This course focuses on data collection to provide information about the overall condition of the cable. Students will learn the indicators that cable performance is deteriorating, understanding the signs that cable is about to fail and when to perform maintenance.

To receive 3.2 CEUs, the participant must attend 4.5 days of class (32 contact hours) and attain a minimum average grade of 80% (overall grade will consist of 50% lab and 50% final exam).  Upon completion of this course and lab practice, the participant will demonstrate that he/she is able to:

• Identify medium voltage cable components and causes of failure.
• Utilize safe work practices for cable testing per OSHA and industry consensus standards.
• Interpret current industry cable testing standards and procedures.
• Perform and analyze results of:
  • Insulation Resistance Tests (DAR and PI).
  • Withstand Tests (DC, AC & VLF).
  • Diagnostic Field Tests (Tan Delta & PD).
• Outline the benefits gained by establishing a Conditioned Based Cable Maintenance Program.

CERTIFIED FIBER OPTIC TECHNICIAN (FOA) (CFOT | #404C)
4.5 DAYS | 3.2 CEUs

In this course, students will learn how to understand the limitations of bending, effects of temperature, how to effectively splice and connectorize fiber optics, troubleshoot a system and confirm the quality of connections and splices. All these skills are necessary to properly install and repair fiber optics systems.

Participants completing the course exercises and lab requirements will be given the Fiber Optic Association (FOA) exam for Certified Fiber Optic Technicians. This exam is proctored by a certified FOA instructor and participant must score the minimum (70%) to meet the FOA certification requirements.

To receive 3.2 CEUs, the participant must attend 4.5 days of class (32 contact hours) and attain a minimum grade of 70% on the final exam. Upon completion of this course, the participant will demonstrate that they are able to:

• Identify and specify components for a fiber optic system.
• Determine the appropriate fiber for different applications.
• Install fiber optic cable and test for EIA/TIA acceptable losses.
• Utilize fiber optic test equipment including an optical time domain reflectometer (OTDR), light source, and power meter.
• Perform fusion splices and test them mechanically according to EIA/TIA standards.
• Identify damage to cables and the associated causes.
• Utilize attenuators to adjust power levels (dBm) at the receiver.
