Earthing & Bonding

Electrical “Grounding” has two parts: an “earthing” and a “bonding” function.

Effective earthing is a necessity for all electrical and electronic systems. It provides low resistance path for fault current, shield from external surges, maintains equipotential protection system, provides a path for dissipating energy from external source and act as a reference for protection system.

Effective bonding is needed to allow current to flow seamlessly, assuring that a circuit breaker will trip or fuse will blow during short circuit or overload scenario. Bonding is the way of joining of two electrical conductors together such as wire to wire, wire to the pipe, or between two Types of equipment. Bonding ensures equipotential between two points.

Commissioning Of Earthing System

Proper commissioning of an earthing system is essential to maintain safe touch & step potentials over the grid and also provide a low resistive path to the fault current. We validate the design and installation process by performing site supervision during installation and also remeasure the earthing system in terms of potential rise, current distributions and the grid resistance to observe its deviation from its designed state.

Validation Of Existing Earthing System

Validation of existing earthing system is essential maintenance activity. This enables to check the present earthing system’s condition with respect to its designed criteria. We provide easy, economical implementable solutions which the maintenance department can adapt and reduce the deviation from designed earthing system.
