    HV phase lost, strange voltages on LV side

    Hi, Storme Katie dislodged one of the HV jumpers on the DNO 11 KV network, so the local 11KV 415 transformer was single phasing. I expected to get 240, or 120V but there were some people getting 150V and I got about 70 volts and it was indepenent of load. I am trying to work out why not 120V? Thanks

    2.5mm2 Ring Final Circuit vs 4.0mm2 Radial

    I recently read an article about the advantages of both the RFC and Radial circuits, after which I must admit that I am more swayed towards the Radial. What are others thoughts? What do you prefer and why?
