ASHLOK SAFE EARTHING ELECTRODE LIMITED ----an ISO 9001:2000 certified company & SIGNET COMPONENTS PVT. LIMITED Presents Patented Maintenance Free Earthing System CTM  S.E.E

What you expect a Good Earthing to be. Good Earthing must have impedance low enough to ensure that sufficient current can flow through the safety device so that it disconnects the supply. It should resist the corrosion. It should have sufficient mechanical strength to hold the maximum fault current repeatedly. CTM  S.E.E

Gen-next technology demands better solution: Which: Protect electrode from corrosion Reduce earth resistivity Increase moisture content in soil Is it possible ? CTM  S.E.E

Is it possible in conventional earthing “Sorry” Is it possible in conventional earthing “Sorry” The Salt used in conventional earthing pits gets dissolved in water and corrodes the electrode very fast The earth resistivity fluctuates with seasonal changes. CTM  S.E.E

Pipe in Pipe/Life in Pipe Safe Earthing Electrode There are two pipes, one inside the other i.e., pipe- in- pipe technology Safe earthing electrode is not in direct contact with the soil. Absence of corrosion Least fluctuation of Ohmic value. Since SEE is surrounded by highly conductive soil so the charge dissipation through the electrode is very high, sufficient to trip the fault relays CTM  S.E.E

Pipe in Pipe/Life in Pipe Safe Earthing Electrode.... Two ‘B’ class mild steel pipes, one inside the other, are subjected to Hot Dip Galvanization : micron on secondary electrode and 250 – 300 micron on the primary electrode. Empty space inside the primary electrode and the secondary electrode is filled with CRYSTALLINE CONDUCTIVE MIXTURE and then sealed. CTM  S.E.E

Crystalline Conductive Mixture (CCM) Crystalline Conductive Mixture (CCM) Contains metal alloys and natural compounds High conductive, Anticorrosive Does not disintegrate or collapse even when outer electrode becomes inactive. CTM  S.E.E

Back Fill Compound (BFC) Back Fill Compound (BFC) Contains eco-friendly materials. Contains eco-friendly materials. Maintains moisture and enhances conductivity around the electrode. Maintains moisture and enhances conductivity around the electrode. Does not mix with or leach in to the normal soil. Does not mix with or leach in to the normal soil. Reduces soil resistivity around the electrode. Reduces soil resistivity around the electrode. No need to recharge pit. Except in sandy/rocky areas. No need to recharge pit. Except in sandy/rocky areas. As the moisture mixes with the BFC, an electrolytic solution is formed which i mproves electrode performance As the moisture mixes with the BFC, an electrolytic solution is formed which i mproves electrode performance CTM  S.E.E

What is Soil Resistivity? It is the resistance of soil to the passage of electric current It is the resistance of soil to the passage of electric current It varies from soil to soil It varies from soil to soil In depends on the composition of soil, In depends on the composition of soil, Moisture content, Dissolved salts, grain size and its distribution, seasonal variation, current magnitude. Moisture content, Dissolved salts, grain size and its distribution, seasonal variation, current magnitude. CTM  S.E.E

Technical Comparison Conventional System Conventional System ASHLOK S.E.E a) Single G.I. Pipe is used as earth pipe. The pipe is galvanized from out side only. Some time additional plate is also attached with the pipe. Pipe-in-Pipe Technology. Two B class M.S. Pipes one inside the other, Hot Dip galvanized, inside space filled with Corrosion Resistant, high conductive crystalline mixture. CTM  S.E.E

Technical Comparison b) GI Pipe Earthing : Corrosion starts and with in years (depending on the soil condition), complete pipe is corroded Conventional System Conventional System ASHLOK S.E.E GI Pipe Earthing based on Pipe in Pipe Technology: Average active life 20 years. c) Charcoal and Salt used corrode the metal. No charcoal and salt. Own compound used as backfill material. CTM  S.E.E

Technical Comparison d) Regular watering of pit to enhance conductivity. Conventional System Conventional System ASHLOK S.E.E Normally watering of pit is not required. However during peak summer few buckets of water in and around earth pits is required. e) Earth resistance value fluctuates Least fluctuation in Earth resistance value. f) More space is required for installation. Very less space is required for installation CTM  S.E.E

Technical Comparison g) Some times fails to activate fault protection relays, due to corrosion. Conventional System Conventional System ASHLOK S.E.E Enough low impedance to activate safety devices. h) Some times fails to provide safe discharge path for fault current, due to corrosion. i) Not cost effective in the long run Highly cost effective in the long run Always provides safe discharge path to fault / surge / lightening currents.
