Safe, rapid aerial surveys for EHV transmission lines, distribution networks, substations, and towers — detecting conductor sag, vegetation encroachment, hardware faults, and corrosion with LiDAR and thermal sensors, eliminating the need for dangerous manual inspection at height.
Traditional power line inspection requires helicopter patrols, linemen climbing live towers, and patrollers walking remote terrain — all dangerous, slow, and expensive. Our drone surveys cover hundreds of kilometres per day from a safe distance, capturing LiDAR point clouds for precise sag and clearance measurements, thermal imagery for hotspot detection, and 4K video for hardware inspection — with lines live and no outage required.
A 500 km transmission line inspection that takes a helicopter team 5–7 days at high cost can be completed by our drone fleet in 2–3 days — with LiDAR sag data, thermal hotspots, and vegetation clearance maps delivered together.
Our drone survey capability covers all voltage levels — from rural distribution to 765 kV EHV national grid transmission.
Overheating compression joints, clamps, and connectors detected via thermal imaging — a leading indicator of imminent failure and arc flash risk.
LiDAR-measured conductor sag at every span — identifies sections where minimum ground, road, or vegetation clearance is violated per CEA regulations.
Trees and vegetation approaching minimum clearance distances — precise identification of which spans require trimming before the next season's growth.
Close-range visual and UV inspection of insulator strings — broken discs, contamination, and tracking marks that reduce creepage distance and risk flashover.
Bent members, missing bolts, corrosion, foundation cracks, and anti-climbing guard damage on lattice towers detected from close-range RGB inspection.
New constructions, buildings, antennas, and unauthorised structures within the transmission line ROW that violate CEA clearance norms.
Surface damage, broken conductor strands, bird caging, and armour rod displacement detected using close-range high-resolution zoom camera imagery.
Earthwire slack, vibration damper loss, OPGW slack or splice box damage detected along transmission line corridors.
Pre-construction route survey for new EHV/HV transmission lines — terrain mapping, tower spotting studies, forest and agricultural crossing optimisation, and ROW planning.
Complete annual inspection of transmission and distribution lines — tower condition, hardware, conductors, and vegetation clearance for preventive maintenance planning.
Targeted thermal drone patrol to find overheating joints, connectors, and hardware before they cause line tripping, fire, or arc flash incidents.
Pre-monsoon vegetation clearance survey — identifying trees and branches approaching minimum clearance, generating a span-by-span tree trimming priority list.
Rapid aerial assessment after cyclones, storms, and floods — mapping tower collapses, conductor breaks, and fallen trees for priority restoration sequencing.
Aerial thermal and RGB inspection of substation equipment — transformers, busbars, switchgear, cable trays, and gantry structures for condition monitoring.
We coordinate with the transmission/distribution utility, obtain line patrol permissions, and follow CEA minimum safe distance protocols. No outage or shutdown is required for standard aerial survey.
LiDAR for sag and vegetation clearance, thermal for hotspots and joint inspection, high-resolution zoom RGB for hardware and insulator inspection — configured per survey objective.
UAV flies the line corridor at safe distance maintaining CEA minimum clearances. Tower-by-tower inspection flights are added for close-range hardware and conductor assessment.
LiDAR point cloud is classified into conductors, ground, vegetation, and structures. Conductor sag, ground clearance, and vegetation-to-conductor distances are computed for every span.
Thermal anomalies, structural defects, vegetation violations, and ROW encroachments are classified by type and severity. GPS coordinates are assigned to every finding.
Complete inspection report with sag profile, hotspot map, vegetation clearance analysis, tower condition ratings, and GPS-tagged fault inventory — delivered within 48–72 hours.
