    tank gnd

    I have wye to wye pad mounted three phase customer owned xfmr x0/h0 bonded. Customer owned Hv side compartment has h1, h2, h3 terminals and ground pad. Customer owned LV side compartment has x1, x2, x3, h0/x0 terminals and additional ground pad. Their is a strap x0/h0 to LV compartment ground pad. I think both compartment sides ground pads are tank ground not sure.

    Question typically:

    1. Do both sides compartment ground pad solidly grounded or just one?

    2. Is their any bonding or connection between two ground pads intenral, compartment to compartment or factory?

    3. Would HV side concentric neutral cable land on HV compartment ground pad?
