Overhead Power Line Patrol Checklist [FREE PDF]

Overhead power line patrol is a critical preventive maintenance activity required under OSHA 29 CFR 1910.269 and NERC transmission maintenance standards to identify conductor damage, structure deterioration, and vegetation encroachment before they cause outages or safety incidents. FERC Order No. 693 mandates utilities to maintain documented transmission line inspection programs as part of their reliability compliance obligations. Routine patrols detect issues such as broken strands, foreign obj

Pre-Patrol Safety Briefing & Authorization

Confirm work authorization, hazard assessment, communication plan, and PPE requirements are established before beginning patrol.

  • Has a job briefing been conducted covering all hazards for this patrol route?
  • Has the patrol crew confirmed communication methods and check-in intervals with dispatch?
  • Is all required PPE inspected and available including rubber goods for any required approach work?
  • Is the patrol vehicle or aircraft airworthy / roadworthy and equipped with emergency response kit?
  • Has the patrol route been reviewed for known hazards, third-party construction, and prior damage reports?

Transmission Structure Condition

Inspect poles, towers, and cross-arms for structural integrity, corrosion, damage, and foundation condition.

  • Are all structures (poles, towers, H-frames) plumb, structurally sound, and free from visible lean or settlement?
  • Are steel towers and metal structures free from significant corrosion, missing members, or broken welds?
  • Are wooden poles free from woodpecker damage, rot, splits, or excessive checking?
  • Are cross-arms, braces, and pole hardware (bolts, band clamps) intact and free from damage or missing components?
  • Are structure identification numbers and phase marking signs present and legible on all structures?
  • Capture photograph of any structure showing damage or requiring corrective action?

Conductor & Hardware Inspection

Assess conductor condition, hardware, and fittings for broken strands, corrosion, galloping damage, and improper clearances.

  • Are conductors free from visible broken strands, kinks, birdcaging, or splice failures?
  • Are conductor sags within expected limits and no spans showing excessive sag or uplift?
  • Are all suspension and dead-end hardware fittings (clamps, sockets, links) intact with no cracks or excessive wear?
  • Are vibration dampers present in required locations and free from displacement or damage?
  • Are OHGW (overhead ground wire) and shield wires intact and properly bonded at each structure?

Insulator String & Surge Arrester Condition

Inspect insulator strings, disc insulators, line post insulators, and surge arresters for flashover damage, contamination, and missing hardware.

  • Are insulator strings free from broken, cracked, or missing discs/units?
  • Are insulators free from heavy contamination, bird deposits, or tracking marks that could cause flashover?
  • Are polymer/composite insulators free from corona erosion, shed damage, or housing delamination?
  • Are surge arresters free from visible damage, cracks, or evidence of recent flashover or wildlife contact?
  • Are all corona rings, grading rings, and arcing horns in place and undamaged where required?

Vegetation Management & Right-of-Way Clearance

Evaluate vegetation encroachment, right-of-way condition, and compliance with minimum clearance requirements to prevent flashover and wildfire ignition.

  • Does all vegetation within the ROW maintain the minimum required clearance distance from conductors?
  • Are there any Grow-In or Fall-In vegetation risks identified that require immediate or scheduled trimming?
  • Is the right-of-way free from unauthorized structures, stored materials, or encroachments?
  • Are there any areas of the ROW with evidence of wildfire fuel accumulation requiring hazard abatement?
  • Record total number of structures or spans requiring vegetation work orders on this patrol segment?

Third-Party Activity & External Hazard Assessment

Identify construction activities, foreign attachments, public safety hazards, and other external threats to line integrity.

  • Is there any construction, excavation, or drilling activity observed within the ROW or in proximity to structures?
  • Are any foreign objects (kite strings, balloons, tarp materials, cables) found on or near conductors or structures?
  • Is there evidence of vandalism, theft of hardware, or unauthorized climbing of structures?
  • Are all access roads and gates to the ROW serviceable and secured?
  • Are any aviation obstruction lights on tall structures operational and functioning correctly?

Grounding System & Foundation Assessment

Inspect visible grounding conductors, ground rods, and structure foundations for integrity and continuity.

  • Are visible ground conductors on all structures intact, properly connected, and free from corrosion or damage?
  • Are structure foundations (pier caps, anchor bolts, guyed anchor heads) free from visible cracking, erosion, or heaving?
  • Are guy wires and anchor assemblies properly tensioned, free from broken strands, and with guard guards intact?
  • Is there evidence of soil erosion, washout, or undermining at any structure base or anchor point?

Patrol Summary, Deficiency Log & Closeout

Summarize patrol findings, log all deficiencies with structure numbers, and complete sign-off for the patrol record.

  • Total number of structures patrolled on this inspection segment?
  • Were any IMMEDIATE hazards identified requiring same-day emergency dispatch?
  • List all structure numbers, deficiency descriptions, and recommended corrective action priority?
  • Have all immediate hazards been reported to operations control and work orders initiated?
  • Patrol end time and total route distance covered?
