Test Instruments & Troubleshooting

Test Instruments & Troubleshooting


One of the most significant tasks performed by lineworkers is the troubleshooting process. This is a utility operation where hazards are easily unrecognized, customer relationships can be damaged, and substantial material loss may result. Helping lineworkers develop troubleshooting skills, or enhance their existing skills makes them safer on the job and better equipped to facilitate a positive customer interaction. Whenever a truck rolls, a safe and successful completion should be our aim. This class typically requires two days.

this course covers:

  • troubleshooting – the investigator’s toolkit
  • non-technical information (what did they say? what is tribal knowledge?)
  • the five questions
  • Ohm’s law
  • series circuits, parallel circuits, open circuits, faults and overloads
  • low voltage meters – settings, calibration, fusing, TOV and CAT ratings
  • customer side basics – single and double pole breaker, GFCI, AFCI, load characteristics
  • meter socket checks – weatherhead connections
  • investigating the service – beast of burden, min/max, infrared, considerations for sockets
  • transformers – visual keys, Xfmr checker, ringing for continuity, CLF’s, energizing to test
  • transformer connections – diagnosis and precautions
  • phasing
  • high voltage instruments – Xfmr turns ratio, HV detector operation, calibration, checking
  • wire brush conductors, connectors (good, bad, ugly)
  • safety during troubleshooting – gloves, glasses, tuck button and roll, impending failure
  • elementary PQ and non-linear loads
