Maximum distance to house from transformer
Posted: Thu May 12, 2022 4:06 pm
Hi All.
We have just purchased some rural land in northland. There is a Northpower powerline and powerpole (and transformer I think) at one corner of the site, but the potential residential building site is about 1km away up the gravel right-of-way.
What is the maximum distance that a 240V line could be run to a house? I'm guessing that 1km is too far?
I assume that the Northpower line is High Voltage (2kV? 6.6kV? what is normal?), so another option is to run a HV cable up to nearer the building site and then transform it down to 240V. Can an HV line be undergrounded? How expensive would this be for 1km of undergrounding etc?
Thanks! Dave
