FAST ELECTRODE EARTHING |
CONVENTIONAL EARTHING |
1 |
There are two pipes one inside the other,ie pipe in pipe technology |
Only a single Pipe or plate either GI/CI/Cu of particular dimension |
2 |
Fast Electrode is not in direct contact with mother soil |
The pipe or plate is in direct contact with mother soil. |
3 |
Corrosion rate is very slow |
Liable to fast corrosion, subsequent decay |
4 |
No fluctuation of ohmic value. |
fluctuation of ohmic value is more results in frequent maintenance of machine & also danger to human life |
5 |
Ohmic value reduces with time |
Ohmic value increases with time |
6 |
Since FAST ELECTRODE is surrounded by highly conductive soil so the Charge Dissipation through the electrode is very fast.
& the current density across the
electrode is very low which results
in very high fault current, is sufficient
to trip the fault relays. |
Distribution of short circuit is less in terms high potential at the pit which result in low fault current in comparison to required tripping circuit of fault protection
|
7 |
Galvanization is adequate i.e., 80-100 |
Galvanization is not adequate.
microns |
8 |
There is an additional zinc coat on the outer surface |
No additional zinc coat is given |
9 |
Fast Electrode. is non – corrosive, so there is
not much variation in ohmic value. |
Salt, charcoal is used as back fill
compound, as salt is highly corrosive
electrolyte, it corrodes G. I. / C. I.
electrodes / G. I. & copp er earth plate.
Finally get the high ohmic value |
10 |
The Earth enhancing compound is not soluble in
Water & it becomes part of the soil around the electrode. |
Back fill compound (salt) used will be
Washed away in rainy seasons & will be resulted in high ohmic value.

11 |
It requires less space & time to install |
It requires a large space & time to install |
12 |
FAST ELECTRODE is tested IN CPRI for 42 Kamp rms. |
No testing is avaible. |
13 |
The PH value is between 7 to 9 shows basic in nature |
PH value shows acidic nature. |
14 |
Earth Enhancing compound tested & certified by NABL approved Lab. |
No certification is avaible |
15 |
Earthing compound doesn’t contains any graphite or carbon content. |
May be a combination of carbon content. |
15 |
Doesn’t affect the soil fertility |
Affect the soil fertility |
16 |
Life Is more than 20 years |
Life is 4 to 6 yrs. |
17 |
Assured results. |
No assurance |
18 |
Earthing should be done deeper in mother soil |
Most of the times earthing is done in a 4 to 5 feet deep soil, where the soil is nearly a dead soil & no conductivity there. |

Fast Electrode |
Conventional Earthing |
1 |
Life span is 3 times more than conventional type cost of one earth pit |
Compensate cost of 3 electrodes |
2 |
Low cost of excavation |
High cost of excavation |
3 |
No cost of maintenance. |
Additional maintenance cost is there. |
4 |
No regular watering is required |
Regularly watering is required. |
5 |
No cost of Charcoal & salt |
Additional cost of charcoal & salt |
6 |
In Rocky, sandy & filler soil excavation cost is low & easy to install |
In rocky sandy & filler soil digging is a tedious job. |
