Course Guides


Cable Fault Locating

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 using the most innovative TDR (Time Domain Reflectometer) techniques and best portable contact thumper the market has to offer. It will also focus on ways to reduce fault location time and allow for quick sectionalizing of faulted loop feed URD (Underground Residential Distributions).

Training is usually held over the course of 3 days.

Learn How To

  • Isolate faulted sections using advanced sectionalizing techniques
  • Locate and interpret cable faults with TDR (Time Domain Reflectometer) waveforms on radial and loop feed systems
  • Pinpoint cable faults with Ballistic and Acoustic Listening Devices (FlashPhone)
  • Verify integrity of cable insulation

Transformer Diagnostics

Testing of transformers is important for both manufacturers and end users. Manufacturers need to be certain their units are meeting the desired specifications, while end users need to perform regular maintenance procedures to detect minor fault symptoms before timely and costly failures occur. This course is designed to help transformer manufacturers, utility and contract workers, repair companies, and research labs satisfy their testing needs.

This training is usually held over the course of 2 days.

Learn How To

  • Measure insulation resistance
  • Measure polarization index
  • Perform winding resistance measurement for any size transformer
  • Assess condition of transformer insulating oil with dielectric withstand tests
  • Measure short circuit impedance of power transformers at reduced current
  • Measure power factor and dissipation factor to detect aging and deterioration within the insulation of the transformer
  • Run three-phase and single-phase turns ratio meters (TTR)
  • Perform capacitance and tan delta testing
  • Conduct frequency response analysis to verify mechanical/electrical integrity

Aerial Lift Testing

Protecting the lives of lineman and ensuring their overall safety is a top priority for both utilities and tree removal companies. This course provides step-by-step training on how to test the electrical strength of boom insulators (per ANSI Standard A92.2) as well as the voltage withstand ability of hydraulic hoses and the oil they contain. Moreover, we will shed light on test results implying dielectric failures due to: contamination of the insulator surfaces; chemical (internal or external) deterioration of the insulator; aging or degradation of the fiberglass/rubber insulating material; moisture absorption; substitution of improper insulating material with inadequate dielectric constants or voltage withstand ability.

This training is usually held over the course of 1 day.

Learn How To

  • Properly apply high voltage across the “insulator” portion of the boom
  • Measure the resulting current flow through the insulator in accordance to ANSI Standard A92.2
  • Improve on skills required to record and interpret test results
  • Learn how to properly position lift trucks (both articulating and telescoping) for acceptance and maintenance testing
