Earthing Electrode

National Power Industries are leading producer of earthing electrode in india, Apart from dealing in earthing solutions and lightning protection equipment we also have a remarkable name for our product earthing electrodes. Since Last 51 years Marketed under the brand name of national National Power Industries, these electrodes are acclaimed for features like corrosion resistance, eco-friendliness, excellent efficiency, etc., and are widely used in various application areas such as telecommunication towers and microwave antennas

Purpose

To eliminate electrostatic discharge to save sensitive equipments and to avoid disturbance in Power supply by providing effective earthing- The most important aspect in electrical industry.

Benefits

Earthing electrode is easily installed with less space required as compared to conventional earthing and yet has a longer life. Earthing powder which surrounds earthing electrode is hygroscopic and conductive which helps the longer period of effective earthing. Earthing powder has the quality of absorbing and retaining moisture contents for a very long period. Very low resistance value ensures safe and sound earthing.

Features

Hot dipped galvanized strip in G. I. Pipe where G. I. Strip is primary and G. I. Pipe is outer and Secondary electrode. G. I. Strip helps smooth flow of current. The space between G. I. strip and G. I. pipe is filled with the powder which has conductive and non - corrosive elements which helps longer life of electrode. Earthing terminal is provided directly with primary electrode of G. I. strip which ensures proper earthing. Strip earthing is bettertLan pipe earthing or plate earthing. We have benefits of both strip earthing and pipe earthing

Different Between Safe Earthing Electrode and Traditional Earthing Electrode

Safe Earthing Electrode

Pipe-in-pipe technology, two mild steel pipes one inside the other, hot dip galvanized, filled with high conductive and corrosion resistance crystalline mixture and backfill compound around electrode

More than 99+ Models are available. in which 50mm dia 3 meters is used in place of the conventional GI pipe earthing. 76mm dia, 3 meter is used in the place of the conventional copper plate earthing electrode in Gujarat

Backfill compound is used as in fill material. BFC retains moisture and enhances conduction around electrode

Watering around the earth pit is required for about 3 days after installation and for a few days in peak summer when water tables go down

Ohmic value always within safe limits
Maintenance of pit is not required in normal soil conditions

Low enough impedance to activate fault relays. Due to high conductive soil around the electrode, charge dissipation through electrode is very high, current density across electrode is very low, which results in very high fault current enough to tripfault relays

Always provide safe discharge path to fault current and lightning current
Requires less space and time for installation
Practically no need to change during lifetime
Backfill Compound (BFC) is not soluble in water. It is an excellent ground enhancer
Very Safes Stable Palatform for electronic machinery, equipment and appliance.
Can easily cope with the earthing demands of the new generation electrical/electronic machine
Cost effective investment

Traditional Earthing System

Copper plate earthing inclusive of ms pipe, 50 mm dia, 2.75 meter long, copper plate 405*450*3 mm with copper strip 25*3 (6 bags) plus charcoal and salt around electrode, Oxidation takes place, resistance todissipation increase when corrosion starts

Gi pipe electrode earthing 5 to 10 micron galvanization size 65mm or 38mm * 2.75 m long plus charcoal and salt etc, pipe corrodes fast over a period of 3 years causing high resistance to smooth dissipation of current

Charcoal and salt are used in the pit as in fill material, common salt hastens corrosion of GI/CI electrodes and the resistance value goes over a period of time

Watering of pit required regularly to enhance conductivity around the electrode

Ohmic value fluctuates resulting in frequent maintenance of costly machinery and appliances and danger to human life

Sometimes fails to activate safety devices

Distribution of short circuit is less in terms of change dissipation and therefore generates high potential at the pit resulting in low fault current, insufficient to trip fault protection relays

Some times fails to provide safedischarge path for fault current
Requires large space and time for installation

GI pipe earthing needs to be changed every three years and copper plate earthing every 12 years due to corrosion attacks

Salt as fill materials is washed away during season
Not a stable platform for sensitive electronic equipment and appliances
can't cope with the earthing demands of the new generation machines

The cost of maintenance over a 15 plus year period will be about three times more than the one time cost of electroearths safe earthing electrode
