Summary

In this video, the presenter reviews a compact electrical device used to measure voltage, amperage, and frequency (Hz) in household electrical systems. The device is explained as a tool to monitor the performance of electrical wiring, with a focus on how it measures the 220V standard voltage, 50Hz frequency, and amperage, which is calculated using a coil instead of resistance. The presenter highlights the simple installation process and the benefits of having such a device to track and control electricity consumption, especially during peak hours when voltage may drop.

Takeaways

• 😀 The device measures three key electrical metrics: voltage, amperage, and frequency (Hz).
• 😀 It is designed for household use, specifically for monitoring electrical parameters in home circuits.
• 😀 Voltage readings can fluctuate, such as dropping from 220V to 213V, especially during peak electricity usage times.
• 😀 The device shows frequency as 50Hz, which is typical for electrical systems in Indonesia.
• 😀 The device is compact and can be easily installed in MCB boxes with simple connections.
• 😀 It works by connecting to the positive and negative wires of the electrical system, typically marked red and black.
• 😀 Users can install the device by drilling holes in the MCB box and attaching it with screws.
• 😀 The tool helps users monitor electrical consumption, making it useful for controlling energy usage at home.
• 😀 The device is simple and user-friendly, making it suitable for non-expert individuals to install and use.
• 😀 A bonus feature includes the ability to monitor amperage and frequency, in addition to voltage.
• 😀 Voltage drops are expected during high-demand hours (e.g., nighttime), but will return to normal after peak usage hours.

Q & A

What is the primary purpose of the device mentioned in the video?

The primary purpose of the device is to measure electrical parameters such as voltage, amperage, and frequency (Hz) in household electrical systems.

What are the two main functions the device was initially expected to have?

The device was initially expected to measure voltage and amperage in the household electrical system.

What additional functionality did the reviewer discover about the device?

The reviewer discovered that the device has three functions, not just two: it can measure voltage, amperage, and frequency (Hz).

What is the typical voltage and frequency in Indonesia’s electrical systems?

In Indonesia, the typical electrical system operates at 220V with a frequency of 50Hz.

How does the device measure amperage?

The device measures amperage by using a coil (kumparan), which is installed in the electrical cable, particularly in the red (live) wire.

Why was the amperage reading not visible in the video?

The amperage reading was not visible because the device was not connected to an active electrical circuit (no cables were inserted into the holes for reading amperage).

What might cause the voltage reading to fluctuate during the night?

Voltage fluctuations are common during the night due to higher electricity consumption, leading to a drop in voltage levels (e.g., from 220V to 213V).

What can be concluded from the reviewer's experience with the device's performance?

The reviewer concluded that the device is useful for monitoring and controlling household electricity, providing insights into voltage, amperage, and frequency, which can help manage electrical systems more effectively.

How does the device connect to the electrical system for measuring voltage and amperage?

The device connects to the electrical system through two terminals, X1 and X2, where the positive and negative electrical wires are connected, enabling it to measure voltage and amperage.

What type of installation is required for the device to function properly?

The device requires installation by drilling a hole of approximately 3 cm diameter in the electrical system's casing, through which it is mounted using bolts for stability and secure connection.
