Earth resistance measurements significantly differ from other measurements performed to assess the protection against electric shock. They require a thorough knowledge about the construction of the earthing system, the phenomena occurring during the measurements and methods for managing difficult field conditions. Persons performing tests and measurements of ground systems must have appropriate knowledge and measuring equipment able to support such complicated task.
The video shows methods used in earth resistance meter MRU-120HD such as:
2-pole method (2p) - measurement of continuity of protective connections and equipotential bondings,
3-pole method (3p) - measurement of earth resistance by the technical method,
4-wire method (4p) - which eliminates the influence of the test cable resistance on the measurement result,
3p-method with clamp - allowing multiple earthing resistance measurement without disconnecting the test connection,
two-clamp method - allowing the measurement of earth resistance without auxiliary electrodes,
ground resistivity – Wenner method.
