To comply with the Official Mexican Standard NOM-022-STPS-2015, Static electricity in work centers - Safety conditions, it must be verified that the ground resistance values ​​are less than or equal to 25 ohms for the ground resistance of the grounding network and 10 ohms for lightning rod systems.

 

It is advisable to carry out resistance measurements of physical grounds and lightning rods, at least once a year,in order to detect if the values ​​established in the standard are being met, if there is any failure in the system, if any conductor has lost continuity, or if a sulfation in the connectors is present.

 

PREVENTIVE MAINTENANCE

•Inspection of the physical conditions of electrodes, registers and connections.

•Cleaning and retightening of connectors.

•Label and paint the register box.

•Measurement of resistance of the earth system by means of the Fall of Potential Method with a spike terrameter.

•Continuity measurement of connections.

 

CORRECTIVE MAINTENANCE

•Application of soil intensifying compound.

•Application of electrolyte.

•Replacement of connectors.

•Electrode replacement.
