Difference between Bonding and Grounding

Bonding vs Grounding Bonding is the lasting joining of metallic pieces to form a conducting path which ensures safe electrical continuity. Bonding is generally done as protection from electrical shocks. Any intentional or accidental connection between an electrical circuit or instrument and the earth is known as Grounding. Grounding ensures that all metal parts of…

Working of Buchholz Relay

In the field of electric power distribution and transmission, a Buchholz relay is a safety device mounted on some oil-filled power transformers and reactors, equipped with an external overhead oil reservoir called a “conservator”. Buchholz relay is a gas-actuated relay which is used for protection of oil filled transformers/reactors fitted with conservators against low oil…

Types of Earthing & Electrical grounding systems

What is Earthing: The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipment’s are grounded then if the insulation inside the equipment’s fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is…
