R = r1*r2/r1+r2
Four number earthing are essential for installation of transformer as under : 1) Two earthing for transformer body. 2) Two earthing for Neutral Point. Note : Numbers of earthing may be increase as per the client requirement.

Yes, earthing continuity is required for submersible pumps to ensure safety and prevent electrical shock hazards. Proper grounding provides a path for fault currents, helping to protect both the equipment and personnel. It is crucial to adhere to local electrical codes and standards when installing and maintaining submersible pumps to ensure effective earthing is implemented.
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
Some items are double insulated, thus they do not require earthing.

Earthing is always required. It is necessary so that a fault or overvoltage, such as caused by a lightning strike, may be conducted to earth (ground), either dissipating the energy and/or tripping the protective device.
For earthing pipe of 40mm dai & 3 mtr. Long required 5 kg. Of salt & 6.5 kg of charcoal. This type of earthing is done for distribution transformers of various rating.
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
