CARA MEMBAGI MCB 3 FASA DAN 1 FASA

Summary

In this video, the process of dividing a 3-phase MCB system into 1-phase and 3-phase outputs is demonstrated. The presenter explains how to wire and set up a basic electrical panel using MCBs, MCCBs, grounding, and voltmeters for both types of systems. They also show how a selector switch can be used to measure voltages across different phases. The video covers safety protocols, the importance of grounding, and how to troubleshoot voltage issues using voltmeters. This simple guide is ideal for those working with electrical panels in industrial or advanced home settings.

Takeaways

• 😀 MCB 3-phase and 1-phase systems are commonly used in industrial and large residential settings to distribute electricity safely and efficiently.
• 😀 The main MCCB (Molded Case Circuit Breaker) supports the entire panel's load, ensuring safe distribution of power to multiple MCBs.
• 😀 A three-phase MCB typically consists of three breakers, with one dedicated to single-phase output and the other two for three-phase distribution.
• 😀 Busbars are used to organize the connections between the MCBs, making the setup more structured and easier to maintain.
• 😀 The installation of a voltmeter allows monitoring of the voltage on each phase, helping identify any electrical issues quickly.
• 😀 A selector switch is used to measure the voltage of each phase (R, S, T) individually, making it easier to troubleshoot power issues.
• 😀 Grounding is a crucial safety measure, protecting both people and equipment from electrical faults and ensuring safe operation of the system.
• 😀 Single-phase MCBs are typically used for powering smaller loads such as lighting, while three-phase MCBs are ideal for larger equipment like motors.
• 😀 The voltage measurements should be 380V for the 3-phase outputs and 220V for the single-phase outputs, indicating proper system functionality.
• 😀 The panel setup can be used for various industrial applications, including motor control, with a focus on safety and efficient power distribution.
• 😀 The simplicity of this panel setup is ideal for beginners, with more advanced systems being explained in future videos.

Q & A

What is the main purpose of the MCB panel explained in the video?

The main purpose of the MCB panel is to distribute both 3-phase and single-phase electrical outputs, with added functionality to measure voltage and ensure safe operation.

Why is an MCCB used in the panel instead of just MCBs?

An MCCB (Molded Case Circuit Breaker) is used as the main breaker to protect the entire system, as it is designed to handle high fault currents and provide overcurrent protection for the whole panel.

How many MCBs are used for the 3-phase output, and why?

Three MCBs are used for the 3-phase output. This setup ensures each phase is independently protected, allowing for proper distribution of the 3-phase load.

What role does the grounding play in this electrical panel setup?

Grounding is essential for safety, as it ensures that any stray current is safely directed to the earth, preventing electrical shock hazards and protecting both people and equipment.

How is the voltage for the 3-phase system measured in this panel?

The voltage for the 3-phase system is measured using a voltmeter connected to a selector switch. By switching the selector, the voltage for each individual phase (R, S, T) can be checked.

Why are both 3-phase and single-phase outputs needed in the panel?

Both 3-phase and single-phase outputs are necessary because they serve different types of electrical loads. The 3-phase output is typically used for heavy machinery, like motors, while the single-phase output is used for lighter loads, such as lighting and small appliances.

What does the speaker mean when referring to 'busbar sisir' in the setup?

'Busbar sisir' refers to a busbar comb, which is a compact conductor used to connect and distribute the phases from one MCB to another, simplifying the wiring process.

What should be done if a voltage drop or issue occurs in the 3-phase system?

If a voltage drop or issue occurs, the voltage at each phase should be checked using the voltmeter. This can help identify which phase is faulty or disconnected, allowing for quicker troubleshooting.

How is the single-phase voltage measured and monitored in the panel?

Single-phase voltage is monitored by connecting a voltmeter across the neutral and the phase wire of the single-phase MCB. This setup allows for the measurement of 220V output.

Can this panel setup be used for residential applications?

Yes, this panel setup can be used in certain residential applications, especially for multi-story buildings or homes that require 3-phase systems for pumps or heavy appliances.
