GI Earthing Electrodes
Gi earthing is the process of creating alternative path for the flow of faul/excessive current safety into the ground in the presence of minimal resisitence or impedence.
Features
Hot dip galvanized for corrosion protection.
Designed for fast fault current dissipation.
Low maintenance on site.
Easy and fast installation at site.
Most suitable for soil condition with oh value between 5.0 to 8.0.
Moisture booster chemical bag provide for low earth resistance.
Not need to pouring water.
Low space require at time of installation.
COMPARISION BETWEEN TRUE POWER EARTHING AND CONVENTIONAL EARTHING SYETEMS
1) TRUE POWER EARTHING SYSTEMS
Pipe in strip design
Outer section hot dip galvanized
Anti corrosive crystalline conductive mixture(CCM)
Extra high current carrying capacity of 80kmp for 1sec
Electrode not in direct contact with soil as result longer life
B.F.C used around electrode
Average effective life of 15-20years
Good and consistent earth resistance value over time
No maintenance require over long period
2) CONVENTIONAL EARTHING SYSTEMS
Single perforated pipe.
Inadequate galvanization.
Pipe in direct contact with soil corrosion prone and inefficient in long ron.
Average effective life of 2-5 years.
Low inadequate surface area for current dissipation.
No proper care during manufacturing
Applications
Efficient grounding systems reduce the risk of electrical acring and fire True Power Earthing Electrode improves Reliabilty for many application including.
Lightning Protection systems.
Prevention of accidents caused by static charges and stray current.
Protection of central communication ,electronic and AC Power Systems.
Meeting Grounding safety Requirement for Electrical Substation
For Neutral Earth Systems
