Ze readings on a TT system

Former Community Member
Former Community Member
Hi

I have a TT system on a farm where the ze readings are

L1 = >2000

L2 = 1.43

L3 = 1.41

readings took at the henley blocks directly from the meter. There's voltage on L1 and all the 3 phase equipment runs OK.

can anyone tell me why I'm getting this high reading.


Many thanks

    Hi BR, welcome to the forum!


    1.4 (ohms?) seems a bit low for L2 and 3, could you describe the situation in more detail or if possible a few photos would really help.


    :)


    Hello Weirdbeard,


                                     I have seen steel framed farm buildings with many feet buried in the soil where the steel is used as an earth electrode. Multiple electrodes.
