References to ‘low voltage’ (abbreviated LV) apply to V File Size: 2MB.  · In case of an earth fault in one phase in an unearthed network a phase-ground voltage will appear in the neutral-point and the other two phases will thus have their phase-phase voltage to earth. By using an effective earthing, the voltage can be reduced to 80% of the phase-phase voltage.

CN Earthing Manual Section E2 – Earthing Guidance Notes • to ensure the transformer neutrals are not solidly earthed at any time. This prevents excessive earth fault currents from occurring on the network. This can be achieved in a number of ways and depends on the number of transformer at the site. for the earthing on the network and in customers’ installations. New LV networks shall be designed using Protective Multiple Earthing (PME), whereas extensions and additions to existing LV networks must take account of the existing network conditions and the customer connections. The overriding. The earthing construction manual is not a substitute for the earthing design manual which covers the earthing design in detail. In general the earthing design should be provided by the project planner/designer and the earthing construction manual can then be used to apply the design.
