Why the maintenance-free earthing system is a necessity nowadays?

Fundamentally it is very much important for every organization to pay proper attention to the electrical installation and make sure that there is a good and reliable earthing system installed over there. The good earthing systems are very much important for the people to make sure that the safety of humans, as well as animal life, is always there. It will further make sure that damage to be electrical equipment in the cases of lightning and fault has been bare minimum and there is the timely operation of all the protective devices in all such cases of issues. The maintenance-free earthing is gaining a lot of importance nowadays because of several kinds of advantages provided by it. The resistance of the electrode of the earth will always depend upon the soil resistivity and the type of electrode which has been used by the people in the whole system.

Under the conventional systems, the galvanized iron pipe is utilized as the electrode and for this purpose, a pit is always excavated and then the whole electrode is placed into the center and it is filled with the soil, salt along with the charcoal. The conducting of the current into the whole conventional electrode is an electrolyte. Hence, the regular washing and charging of the whole earth pit with salt is also very much important to maintain low resistance of the earth. The regular and normal maintenance of the electrodes of the earth becomes a very important challenge proposition due to several kinds of reasons and some of those reasons are mentioned as follows:

Normally a typical and particular type of installation of earthing requires four types of earthing which include the lightning, safety, system and electronic.

In most of the commercial projects into the cities then the earthing is only possible into the basements and not everywhere else.

Into several kinds of projects where all the open areas are used for earthing the landscaping can also be done and companies dealing will also hide of the earth electrons.

In the cases where electrodes are easily accessible the willingness to properly maintain is normally lacking among the people who further lead to several kinds of issues for the earthing process and there is no enhanced safety level at the end.

The season will play a very important role in the whole resistance of the electric electrode in India being a very tropical country we are nine months is the dry season and it is very much important for the people to pay proper provisions of watering as recommended by the Indian standards which ultimately becomes very challenging for the people. Even the raising of moisture content up to 5% into the dry season the earth pit requires approximately 4 liters of water which is almost impossible in the cases where there is so much scarcity of water. Hence, to get rid of all these kinds of things and because of such practical constraints, the watering of the electrode as well as the charging with salt is not done regularly which ultimately lead to several kinds of issues in the long run and safety levels are not that much effective.

Hence, the earthing process becomes ineffective in all such cases because there is no standardization neither in the electrode nor in the backfill. There are no commercial grades casting of the iron plate or the galvanized iron. The salt will always react with the electric electrode and will lead to corrosion and other associated issues in the long run. The salt will dissolve into the water which will further reduce the connectivity and resistance will be increased with time. These kinds of things are not suitable for the places which are flowing water or high water table. Also, there are several kinds of things which could be because of imbalance into loads, harmonics and several other kinds of things which will ultimately lead to corrosion in the long run. Hence, it is highly advisable for the people to always go with the option of maintenance-free earthing solutions which is only possible in case the soil has been treated around the critical area of the whole electrode.

The organizations must go with the option of taking the advantage of advanced technology in the field of earthing which will always depend upon the chemical compound as it will directly influence the critical area all around the electrodes as per the international standards. This particular type as well as the quality of backfill compound will also determine the long-term based reliability factor of the grading system and it is important to go with the option of following the Indian as well as international standards surrounding the electrodes so that resistance of the earth can be significantly reduced and a proper series of tests must be carried out to ensure that none of the compounds includes any kind of harmful chemicals. Hence, it is also very much important to test all these kinds of compounds for confirming to several kinds of standards because approximately 50% of the water requirements in the nations like India are made through the groundwater and the people need to backfill compound to be utilized in the earthing system so that underground water resources are never polluted.

Hence, going with the option of advanced level maintenance free earthing system which is based upon chemical-based earthing is a very important idea for the people to be implemented as per the national as well as international standards like IEC 60364, IS3043, BS7430 and several other kinds of things. These kinds of systems will normally include the steel and copper-based bonded electrodes with the help of carbon-based conductive surfaces and the concrete backfill and such compounds will also have a higher level of resistivity level of less than 0.1-ohm meter when it will be tested as per the international standards like IEC 62561/7 which is a backfill material that surrounds the electrodes and will make sure that no periodical watering as well as charging is required. Hence, implementation of the chemical earthing price is very much genuine in comparison to the benefits provided by it and the best one is that the people concerned will always be relieved from the issues like maintenance of holding and safety and security will be easily ensured.
