In an electric power system, a fault, of many types, can develop at any time. There are in fact many reasons for which your electrical system gets affected. These faults represent a direct threat to human lives and valuable assets. Therefore Earthing / Grounding system is necessary to dissipate the fault current, trip the protective devices, so that our valuable assets and people remain safe.
Realizing the need of the hour in this domain, Earthing systems were introduced to direct the fault currents into the ground. Grounding or Earthing in the electrical wiring system means a connection with earth through a conductive Earth Electrode, buried in the earth. This is connected to the exposed metal parts of all the equipment, and specific points like neutral of Alternators. These have to have sufficient current-carrying capacity, both for the fault current and fault duration. In this way it prevents the going live of exposed conductive parts of the equipment.
At the same time the high fault current will ensure that the safety devices like MCB MCCB trip, and disconnect the power, rendering the faulty equipment harmless. This is the two fold reason for us to ensure that our installations are properly earthed.
Earlier the options for Earthing were quite limited. The traditional grounding system was typically a big metal electrode, like a pipe, rod or plate, more recently Galvanized, i.e. Zinc-Plated.
Earlier cast iron pipe or plate was also used. This earthing system required maintenance, adding moisture in the earth from time to time to make the pit conductive.
This conventional grounding system was unreliable, and just when you need it, you find that the salt had washed away, leached away, the coal became fluffy, earth terminal resistance has gone high, and became ineffective.
So at the time the people or assets could not be protected, that is when we find that the earth is not functioning. Further the salt corroded the electrode materials, the chemical earthing electrode, being of iron mostly, had started corroding from day-1, adding to the earth pit resistance, reducing current carrying capacity, and unable to trip the safety devices.
As technology changed, it brought a significant shift in the earthing philosophy. Initially, Chemical Earthing was introduced. Chemical earthing has changed the way earthing system was viewed.
Now we have a range of rods and electrodes made from various highly conductive materials which are connected to the equipments with strips and other accessories in the chemical grounding process. Special compounds to fill in the earth-pit, around the electrode, along with the new types of earth Rods and earth Electrodes, ensure that these earthing systems provide you an incredibly longer working life of 20-30 years. These are reliable and require minimal to NO maintenance. JMV LPS Limited is a pioneer in customizing different types of Chemical Earthing Electrodes in a variety of sizes as required by the customers.
