Earthing, also know as grounding is a fundamental and essential part of an electrical system. It protects
instruments, infrastructures, people and livestock from dangerous potential differences. Earthing is “the process
in which the instantaneous discharge of the electrical energy takes place by transferring charges directly to the
earth through low resistance wire (wiki definition)” Earthing can be done by connecting the electrical
equipments to earthing systems or electrodes placed near the ground soil or below the ground level.
The earthing is the common element to which structural units, electrical units, conduits, etc. are directly or
indirectly connected. It’s poor condition or incorrect operation may affect safety components (SPD's, insulation,
etc.) and functional components (filters, measurement lines, resetting of computers, loss of communications, etc.
screens, etc.) of electrical installations. Earthing also minimizes electromagnetic noise, improves signal quality,
improves measurement accuracy of sensors, etc. Bad earthing can generate permanent surges that can damage
equipment and even cause electrical fires.
Periodic checks of the earthing system is essential to verify the state and functionality of the installation. The
detection of the activity caused by defects or malfunctions in the earthing system serves as an indicator of failure
or degradation, which allows risk situations to be anticipated, as well as optimizing maintenance, etc. To avoid
complete earthing failure, it is extremely important to ensure quality of earthing by means of regular or
continues check-ups.
Smart Earth Monitoring Systems is an innovative and high quality real time system to monitors earthing
quality that helps in preventive or corrective maintenance and provides adequate levels of safety for people and
equipment. It measures the resistance of the earthing Pit and the continuity of the grounding conductor with
Equipment, Leakage Current and Neural to Earth Voltage continuously. It allows the earthing system to be
monitored at regular and programmable intervals (hourly, daily, weekly).
