*Earthing* (or **grounding**) is a vital safety mechanism in electrical systems, used to prevent electric shock and damage to equipment by providing a safe path for fault current to flow into the ground.

⚡ *Types of Earthing Systems*
Here are the main types of earthing commonly used in electrical installations:
---
1. 🧱 *Plate Earthing*
*Method:* A copper or galvanized iron (GI) plate is buried vertically in the ground (about 3–4 meters deep) with layers of salt and charcoal.
*Use:* Common in residential and commercial buildings.
*Advantage:* Reliable and widely used; provides a low-resistance path.
---
2. 🌀 *Pipe Earthing*
*Method:* A GI pipe (typically 38–100 mm diameter and 2–3 meters long) is buried vertically with salt and charcoal around it.
*Use:* Most economical and preferred for sandy soil.
*Advantage:* Better performance in moisture-retaining soil.
---
3. 📏 *Rod Earthing*
*Method:* A copper or GI rod is driven into the ground.
*Use:* Used when space is limited.
*Advantage:* Simple and less costly than plate earthing.
---
4. 🔄 *Strip or Wire Earthing*
*Method:* A copper or GI strip/wire is buried in a horizontal trench in the ground.
*Use:* Used for systems with large fault currents like substations or industrial plants.
*Advantage:* Suitable for areas with rocky soil or space constraints.
---
5. ⚙️ *Earthing through Water Mains*
*Method:* Using the metal piping of a water supply as an earth electrode.
*Note:* *Now outdated and not recommended* due to risk of disconnection and corrosion.
---
6. 🏗️ *Chemical Earthing*
*Method:* Uses a backfill compound (instead of just salt and charcoal) to maintain soil moisture and resistivity around the electrode.
*Use:* Common in areas with dry soil or poor conductivity.
*Advantage:* Long-lasting, low maintenance, and stable resistance over time.
---
✅ *Purpose of Earthing*
Protects human life from electric shocks.
Prevents damage to electrical appliances due to fault currents.
Stabilizes voltage during lightning or surge events.
Ensures safe discharge of static electricity.
