Traditional labor inpsection power line will be check 2-3 tower per day,but UAS / drone can inspection 25-30 towers in per day.

1. T60 Power Line Inspection Drone
The setup of 6 cross-provincial grids as North China Power Grid, Northeast China Grid, East China Grid, Central China
Grid, Northwest China Grid, and China Southern Power Grid that covers over 514,000 kms 110KV power lines indicates
Chinese power grid is increasingly expanding. The expansion brings a rising workload on power line inspection.
Traditional man-made power line inspection for 100kms requires 20 inspectors to work in one day, which is becoming
difficultto meetthe general inspection demands for modern power lines system.
As a high-tech inspection way, JTT's smart UAV system designed for power inspection has been widely used for
modern power system. It has solved the traditional man-made inspection problems such as high labor intensity, severe
working environment, and low work efficiency and lowered the labor cost of power grid enterprises. UAV system are
unconstrained by the complex landform and becoming popular as a highly efficient way to implement daily maintenance
of power lines and emergencyresponses.
UAV Power Line Inspection Plan
Regular Inspection: conforming to regular periods, UAV implements inspection to power equipments, protection zones
and power lines.
Malfunction Inspection: to find out failure point, failure cause and failure status, the implementer organizes UAV to
inspectpower lines.

2. Specific Inspection: to implement inspection to power lines according to other specific demands, for example,
troubleshooting acceptance check before new power line's operation.
Power inspection solution with 30X zoom camera:
JTT drone with 30X zoom HD camera can be used to recognize and zoom in the target from sky-high and long distance,
inspect the entire lines and daily routines in real time, investigate the details of obstacle. It is mainly aimed to monitor
the electric transmission lines and inspect the power failure, such as inspection route planning, inspection route result
analysis, image/video data management, inspection route info services, inspection route result replay etc.. The system
combines the aerial, video, telecommunication technologies and backstage analysis in order to increase the safety,
efficiency and intelligence ofelectric line inspection.
The faults which the 30X zoom camera can investigate
Basic faults: the protective cap of the tower root is buried, the filling earth is removed or sinking, the groove of the
protective slope is broken,etc..
Tower pole faults: material lost,screw loose,serial number lost,bird nest,ice covering, tower collapse
Wireway faults: wire distortion and strand broken, wire is burned by the fault current, the spacer bar between the
strapping rings is broken or with foreign substance,etc..
Overhead ground wire faults:strand broken, abrasion,thunder strike,foreign substance,etc..

3. Insulator faults: current burning, fouling, self destruct, mandrel exposed, heating caused by
moisture, abnormal discharge,low or zero electric scale,etc..
Passageway faults: quarry in the way, high trees, building construction and other dangerous factors; metal items
problems such as defect, distortion, displacement of clamp and shock proof hammer; ground items problems such as
discharging burning,ground wire exposed,boltloosening,etc..
30X Optical zoom camera useful case：
1. Daily tour
Full tower inspection Tower mark inspection Load inspection
2. Load details enlarge inspection
Bolt inspection Adapter pieces inspection Anti-shaking hammer inspection
3. Electric tower malfunction checking

4. Screw off Missing Pin Anti-shaking hammer missing
Ground wire off shares Bird control breakage Pin off
