Not without seeing the recorded flight data.
And the powerlines had nothing to do with it.

I agree with Meta4 definitely not the power lines .
Power lines are very good at bringing drones down when they fly into them , but they definitely don’t interfere with drones controls .
Good luck with finding the cause of your flyaway .

OK ... you shared a movie of the flight replay in DJI GO4, that isn't what we need in order to be able to assist you ... (even though the shown flight path there show a nice toilet bowl shape, indicating a yaw error due to a magnetic disturbed take off point).

To start with we need the .TXT log from the mobile device you flew with ... read up here under section 3 on how to retrieve --> Mavic Flight Log Retrieval and Analysis Guide attach then the .TXT log in a new post here.

You had an approximately 90° yaw error, almost certainly due to magnetic interference where you powered up. Most likely steel in the building construction. It is essential to check that the aircraft orientation arrow on the map is actually pointing in the same direction, relative to north, as the aircraft itself. If you had done that then you would have seen the problem before takeoff.

 

[slup]

When you started to face the consequence of a wrongly initiated imuYaw at 10m height due to reasons described in @sar104 post above ... the IMU thought that the aircraft was pointing according to the green bar ... imagine that it in reality was pointing more in a westerly direction. If you want this confirmed without any doubt you could provide the mobile device .DAT log ending with FLY081.DAT.

many thanks guys appeciate all the help... so its important that the aircraft is positioned in the same direction as shown on map/phone before takeoff
