earth electrode meaning in Hindi

Examples

1. Connections to the earth electrodes must not only have low resistance, but must have low self-inductance.
2. The Zone extends in a radius from any bonded metalwork such as the site earth electrode system and boundary fence.
3. Pole 3 will continue to operate during the outage and most of the testing in a monopolar configuration with the earth electrodes.
4. Charcoal will be more costly than bentonite and can be shown by analysis that even assuming the charcoal is simply a graphite cylinder around the earth electrode, any improvement over damp bentonite will be slight.
5. Although each station includes an earth electrode, this is used only to provide a neutral reference, and only one of the two electrodes is connected at a given time so that there can be no current flow between them.
6. However, strip earth electrodes, and any non-effectively insulated metallic sheath / armouring of power cables which extend out of this zone would continue to be considered as'hot'for a distance of 100m from the boundary, for a width of two meters either side of the conductor.
7. In 2010, Transpower reported that continuous operation in monopolar mode has caused the HVDC link to act as a galvanic cell with the earth, causing Benmore's Bog Roy earth electrodes to erode as they acted as an anode, and causing the buildup of magnesium and calcium hydroxide deposits on Hayward's Te Hikowhenua shore electrodes as they acted as a cathode.
8. Maintenance outages are planned well in advance to minimise the effects  they are usually carried out in summer when national electricity demand is at its lowest, and on only one pole at a time, with the other pole remaining in operation providing half of the full two-pole capacity, utilizing the earth electrodes providing a path for return current through the ground.
