Abstract— Automatic power factor corrector is designed to improve power factor automatically whenever power factor falls below a certain level. Efficient generation of power at present is crucial as wastage of power is a global concern. As we know, the demand for electrical energy is increasing day by day. Power factor measures a system’s power efficiency and is an important aspect in improving the quality of supply. This paper presents an embedded system for automatic power factor correction with comprehensive power measurements via LoRa wireless communication. It comprises two Arduino Uno-based modules for both transmission and reception., In this system utilising PT and CT sensors for accurate power measurements. Data exchange is achieved through two LoRaWAN modules over a 100-metre range, with real-time power factor and correction data displayed on an LCD at the receiver end. The heart of the system is a capacitor bank equipped with relay switching, intelligently optimising the power factor. A half HP motor serves as the load, exemplifying the practical benefits of efficient power factor correction in electrical systems, ultimately enhancing energy efficiency and reducing costs.

Keywords- Power Factor, Automatic Correction, LoRa Wireless Communication.

What is DOI

DOI:

A DOI will help Author(s) easily locate a document from your citation. Think of it like a Social Security number for the article you're citing — it will always refer to that article, and only that one. While a web address (URL) might change, the DOI will never change.

Where can i find DOI:

  • In IJSREM journal articles, the DOI will be printed with the article itself, usually on the footer of the page
  • If the DOI isn't included in the article, look it up on the website CrossRef.org (use the "Search Metadata" option) to check for an assigned DOI.

Benefits:

  • Allows for a quick and precise search.
  • Article can always be located.
  • Persistent link to its location on the Internet.
  • Easier identification of published articles even if the metadata URL is changed.
  • Aid in citation tracking, ensuring a researcher has accurate metrics on how and where their research outputs are being used or referenced.
