CERCA ELÉTRICA SEM ATERRAMENTO NÃO DA CHOQUE!

Summary

In this video, Francisco Teixeira explains the importance of proper grounding for electric fences. He emphasizes that almost all modern electric fence systems approved by Inmetro require grounding to work correctly. Without it, the fence may seem to be delivering a shock, but it won't actually be sending any electrical current to the perimeter. Francisco demonstrates the difference by showing the effect of proper grounding and how it impacts the fence's performance. He also encourages viewers to ensure proper installation and offers to assist with any questions.

Takeaways

• 😀 Grounding is essential for electric fences: All electric fence systems should have a properly grounded unit to function correctly.
• 😀 Importance of certified units: Electric fence central units must be certified by Inmetro (Brazilian National Institute of Metrology, Standardization, and Industrial Quality).
• 😀 No grounding means no proper shock delivery: Without grounding, the fence may seem to be shocking the perimeter but is actually not delivering a shock.
• 😀 Grounding equipment: A copper rod, typically 1.5 meters long, is used to establish proper grounding by connecting it to the electric fence unit.
• 😀 Grounding affects functionality: A properly grounded fence delivers the intended electrical shock to the perimeter, while an ungrounded fence does not.
• 😀 Practical demonstration: The video demonstrates the difference in behavior when grounding is connected and disconnected from the electric fence unit.
• 😀 Safety concern: Without grounding, the electric fence can give false signals of being active, which can be misleading or dangerous for users.
• 😀 Visual indicators: When the system is properly grounded, sparks can be seen on the perimeter where the shock is delivered.
• 😀 Disconnecting grounding: The video shows that when grounding is disconnected, the fence appears to be working (making the shock sound) but does not deliver the shock.
• 😀 Viewer engagement: The creator encourages viewers to subscribe and reach out with any questions or doubts about electric fences.

Q & A

What is the main topic of the video?

The video discusses the importance of proper grounding for electric fences, specifically focusing on the need for an Inmetro-approved electric fence control panel with grounding.

Why is grounding important for an electric fence?

Grounding is crucial because it ensures that the electric fence can properly send an electrical charge to the perimeter. Without proper grounding, the system may seem like it is delivering a shock but will not actually do so.

What happens if the electric fence is not grounded properly?

If the fence is not properly grounded, it may sound as though it is sending a shock, but no electrical charge will actually reach the perimeter of the fence.

What is the role of the grounding wire in the electric fence setup?

The grounding wire connects the central unit of the electric fence to a copper rod inserted into the ground, completing the circuit and allowing the fence to deliver a proper shock to its perimeter.

What are the components used for grounding the electric fence?

The grounding components include a copper rod, typically 1 to 1.5 meters long, and a wire that connects the rod to the central unit of the electric fence.

What is demonstrated in the video to show the importance of grounding?

The video shows a practical demonstration where the grounding of the electric fence is temporarily disconnected. This visually proves that the fence will not deliver a shock to the perimeter if it is not properly grounded.

What sound does the electric fence make when it is delivering a shock?

When the electric fence is properly grounded, it makes a distinct sound indicating that a shock is being delivered to the perimeter.

How can viewers visually confirm the electric fence is working correctly?

Viewers can confirm the proper functioning of the electric fence by observing the spark on the wall when the fence is grounded and delivering a shock.

What should you do if the fence is not delivering a shock even though it appears to be activated?

If the fence seems to be activated but is not delivering a shock, the first step is to check the grounding. A lack of proper grounding may cause the fence to appear active without actually sending a charge.

What is the recommended type of control panel for electric fences in Brazil?

The recommended type of control panel for electric fences in Brazil is one that is homologated (approved) by Inmetro, ensuring it meets safety and performance standards.
