PERBEDAAN GROUNDING DAN EARTHING | BANYAK YANG BELUM TAHU

Summary

This video explains the difference between grounding and earthing in electrical systems. Grounding is connected to the neutral point of electrical equipment to stabilize current flow and protect devices from electrical surges. Earthing, however, connects to the body of electrical equipment to safely divert leak currents, protecting people from electrical shocks. The video also covers the types of grounding and earthing systems, such as reactance, solid neutral, and resistance grounded for grounding, and various earthing methods like electrodes and plates for better safety. Ultimately, grounding protects devices, while earthing protects people.

Takeaways

• 😀 Grounding connects to the neutral terminal of electrical equipment to manage electrical surges.
• 😀 Earthing connects to the body of electrical equipment to protect individuals from electrical hazards.
• 😀 Grounding protects electrical devices by directing excess electricity to the ground.
• 😀 Earthing protects people by diverting leakage currents from faulty electrical equipment to the ground.
• 😀 Grounding helps maintain a balanced flow of electrical current, ensuring input and output are ideally the same.
• 😀 Earthing helps prevent electrocution, especially in cases of electrical leakage, such as from faulty pumps or electrical panels.
• 😀 Grounding involves systems like reactance grounding, solid grounded neutral, and resistance grounded systems.
• 😀 Earthing involves different electrode systems, including single, connected, and plate electrodes, to ensure effective discharge to the ground.
• 😀 Grounding does not have zero potential, whereas earthing systems are designed with zero potential for safety.
• 😀 Grounding can prevent damage from electrical surges by redirecting excess current, while earthing provides a safety mechanism for human protection from electrical faults.
• 😀 Both grounding and earthing are essential for maintaining electrical safety in equipment and preventing electrical accidents.

Q & A

What is the main difference between grounding and earthing?

Grounding connects to the neutral terminal of electrical equipment to stabilize current, while earthing connects the body of electrical equipment to the ground for human safety, preventing electric shocks.

What is the purpose of grounding?

Grounding stabilizes electrical equipment by channeling any excess current, such as surges, into the ground to prevent damage.

How does earthing protect people?

Earthing protects individuals by ensuring that any leakage current, such as from a malfunctioning pump or electrical panel, is safely diverted to the ground, preventing electric shocks.

Can you give an example of grounding in action?

An example of grounding is a refrigerator, where the neutral terminal is connected to a grounding system that safely diverts excess current into the ground during a surge.

What is the role of earthing in preventing electric shocks?

Earthing ensures that if an electrical fault causes a leakage of current to a metal body (like a pump), the current will flow through the earthing system into the ground, reducing the risk of electric shock.

What types of grounding systems are mentioned in the video?

The video mentions three types of grounding systems: reactance grounding, solid grounded neutral, and resistance grounded.

How does earthing help during lightning strikes?

Earthing helps by channeling the lightning's electrical current safely into the ground through a grounding system, preventing damage to the building or harm to individuals inside.

What are the types of earthing systems discussed in the video?

The video discusses single electrodes, multiple linked electrodes, and plate grounding systems, which are used to achieve effective earthing.

What is the significance of having a low Ohm value in earthing systems?

A low Ohm value in earthing systems indicates better conductivity, ensuring that the system can effectively channel electrical current into the ground, thus improving safety.

What is the difference between grounding and earthing in terms of protection?

Grounding protects electrical equipment from voltage surges and maintains current stability, whereas earthing protects humans from electric shocks by safely diverting harmful currents.
