Introduction

In the world of energy measurement, kilowatthour (KWH) meters play a crucial role in determining the consumption of electrical energy used by consumers. These meters are categorized into two main types: Analog KWH meters and digital KWH meters. Each type has its own unique characteristics, advantages, and disadvantages. At PT. PLN (Persero) Medan Branch, the comparison of these two types of meters is essential to ensure accuracy in measurement and billing to customers.

Differences in How it Works

Analog KWH Meters

Analog KWH meters work using a rotating gear mechanism, where the motion of this wheel is triggered by electricity. Each wheel rotation will display numbers on the dial that shows the amount of energy used. Although simple, this way of working is often vulnerable to disturbances, such as dust or dirt that can interfere with the accuracy of reading. The simplicity of analog KWH meters makes them cheaper and easier to use, but it also makes them more prone to errors.

Digital KWH Meters

Digital KWH meters, on the other hand, use sensor technology and microprocessors to calculate the energy used. Reading is displayed in digital form that is easier to read. The advantage of digital KWH meters is its ability to provide faster and more accurate results, and can conduct further monitoring through data-based systems. Digital KWH meters are more expensive and require more maintenance, but they offer better accuracy and ease of reading data.

Accuracy and Percentage of Errors

A study conducted to test the accuracy of the two types of meters shows interesting results. In analog KWH meters, with cos φ = 1, the percentage of errors ranges from 0.56% to 1.12%. Meanwhile, on a digital KWH meter, the percentage of errors is only 0.4%. When cos φ = 0.5, the percentage of analog KWH meter errors increases to between 0.69% to 1.54%, while the digital KWH meter remains stable at 0.4%. However, in minimum load conditions, an increase in the percentage of errors in the analog KWH meter to 0.75%.

From these data, it can be concluded that digital KWH meters have a better level of accuracy than analog KWH meters. This is very important, especially for industries and businesses that depend on the accuracy of energy measurements for cost calculations.

Advantages and Disadvantages

Each type of meter has advantages and disadvantages. Analog KWH meter, although it is cheaper and simpler in terms of use, often requires more often calibration and is more susceptible to errors. On the other hand, digital KWH meters, although more expensive and require more maintenance, offers better accuracy and ease of reading data.

Advantages of Analog KWH Meters

  • Cheaper and simpler in terms of use
  • Easy to install and maintain
  • Can be used in areas with limited resources

Disadvantages of Analog KWH Meters

  • Often requires more often calibration
  • More susceptible to errors
  • Limited accuracy

Advantages of Digital KWH Meters

  • Offers better accuracy and ease of reading data
  • Can conduct further monitoring through data-based systems
  • Can provide faster and more accurate results

Disadvantages of Digital KWH Meters

  • More expensive and require more maintenance
  • Requires more complex installation and maintenance
  • May not be suitable for areas with limited resources

Conclusion

The comparison between analog KWH meter and digital KWH meter shows that digital KWH meters are superior in terms of accuracy and accuracy. PT. PLN (Persero) Medan Branch, as an electric service provider, must consider switching to digital KWH meters to provide better services to customers. By using more sophisticated technology, companies can ensure that energy consumption is calculated accurately, providing benefits both for customers and the company itself.

The selection between the two types of meters is very dependent on the needs of the user and the available budget. However, taking into account aspects of accuracy and efficiency, digital KWH meters are a highly recommended choice.

Recommendations

Based on the comparison of analog KWH meters and digital KWH meters, the following recommendations can be made:

  • PT. PLN (Persero) Medan Branch should consider switching to digital KWH meters to provide better services to customers.
  • Digital KWH meters are a highly recommended choice for industries and businesses that depend on the accuracy of energy measurements for cost calculations.
  • Analog KWH meters can still be used in areas with limited resources, but they should be calibrated regularly to ensure accuracy.

By following these recommendations, PT. PLN (Persero) Medan Branch can ensure that energy consumption is calculated accurately, providing benefits both for customers and the company itself.
