Earthing of High Voltage Laboratory

摘要

The study discusses salient points about development of a typical earthing mat installation that has been designed for meeting safety requirement for users of a high voltage laboratory. The details of the earthing practice followed and pattern of earthing mat resistivity variation under different conditions are discussed. The effectiveness of a good earthing system demands not only sound knowledge of design of the earthing mat system but also need experienced personals to implement the design during earth digging, filling soft soil, laying earth electrodes their interconnection and proper maintenance and upkeep at regular interval during all atmospheric conditions.
