How close is the high tension line to this plot?
The legal minimum gap between a building and an overhead line is 1.2 m sideways for a line up to 11 kV and 2.0 m up to 33 kV, under the Central Electricity Authority Safety Regulations, 2023, and it widens with voltage. Drop a pin and the check finds the nearest mapped line, its voltage and its distance from the plot boundary, and grades it by the bands for that voltage.

The answer
From the register, with its date and source.
Nothing run yet. The answer appears here with everything this mini adds:

- Danger and caution zones by voltage (11 kV, 33 kV, 132 kV and above)

HT line distance, briefly
An overhead power line above low tension (household) voltage: TANGEDCO 11 kV, 22 kV and 33 kV distribution feeders, and transmission lines of 66 kV, 110 kV, 230 kV and above on towers.
- Statutory gap
- 1.2 m to 2.0 m
Horizontal clearance from a building: 1.2 m up to 11 kV, 2.0 m up to 33 kV, and 0.3 m more for every further 33 kV. Vertical clearance is 3.7 m up to 33 kV.
- Graded by voltage
- 4 bands
A street feeder 6 m away is fine. A 230 kV tower line 6 m away is not. The bands scale with the line, so the grade means the same thing for both.
- Measured from
- The plot boundary
When the survey parcel under the pin resolves, the distance is taken from its edge, not its centre, so a line along the boundary is not under-reported.
How to check the distance from a high tension line to a plot
- 1
Place the pin on the plot
Tap the plot on the map, paste a Google Maps link to it, or use your location while you stand on it.
- 2
Press Run
The nearest line on the TANGEDCO feeder map and the mapped transmission lines is found, with its voltage and name where the map gives them.
- 3
Read the grade
Danger reads Restricted, and high risk and caution read Flagged, each with the voltage and the distance. A line beyond the caution band reads Clear.
When it helps with land
A layout plot under a corridor
Layouts often run a line along a road or a plot edge. Know whether your plot is the one under it before you choose it.
Planning the building
The statutory clearance decides how close walls, balconies and a terrace can come to the line, which can cost a plot its usable width.
Arguing about what is there
The answer names the voltage and the kind of line, so a street feeder is not mistaken for a tower line, or the other way round.
The feeder map shows where a line is drawn, not whether it is built, shifted or planned, so walk the site. Clearance and any shifting of the line are for TANGEDCO (or TANTRANSCO for transmission lines) to confirm in writing, and the restriction is the corridor under the conductors, not the whole parcel.
Questions people ask
What is the safe distance from a high tension line to a house in India?
The legal minimum horizontal clearance from a building is 1.2 m for lines up to 11 kV, 2.0 m up to 33 kV, and 2.0 m plus 0.3 m for every further 33 kV above that, under Regulation 63(3) of the Central Electricity Authority (Measures relating to Safety and Electric Supply) Regulations, 2023. The vertical clearance is 3.7 m for lines up to 33 kV.
What do the danger, high risk and caution bands mean?
They scale with voltage. Up to 11 kV: danger under 1.5 m, caution under 5 m. Up to 33 kV: danger under 2.5 m, high risk under 6 m, caution under 12 m. Up to 132 kV: 8, 15 and 25 m. Above 132 kV: 15, 30 and 50 m.
Is it safe to build a house near high tension power lines?
Building is lawful outside the statutory clearance for the line's voltage. Inside it, nothing may be built, and in the high risk band TANGEDCO's consent is the step to take before a plan is drawn.
Is the whole plot unusable if a line crosses it?
No. The restriction is the corridor under the conductors plus the clearance. Roads, parking or open space can sit under the line, and the rest of the plot can be built on with TANGEDCO or TANTRANSCO consent.
Where does the line data come from?
TANGEDCO's feeder map of distribution lines, with their voltage, name and substation, and mapped transmission lines of 66 kV and above. The map does not say whether a line is built or only planned.
Why does a 9 m gap read Clear for one line and Flagged for another?
Because the bands follow voltage. 9 m from an 11 kV feeder is well beyond its 1.2 m clearance, while 9 m from a 110 kV line is inside its high risk band.
What does it cost?
1 credit per pin, charged only when the layer gives a real answer. The free HT line check page stays available; this check adds the parcel boundary, a sweep of the severe layers and a saved answer.
