HY—Power capacitor series HYFD-2000

Chapter I Summary

1. Summary

With the development of China’s economy, the power supply and use departments have brought forward higher requirements oelectric energy quality. To better control the electric energy quality of terminals and enhance power distributioefficiency, our company has developed the BYFD-2000 power distributiomeasuring and controlling device provided with such functions as real-time circuit parameter monitoring, historical data retrospect, dynamic and static reactive compensatioand etc., playing its good role ihelping users master power supply parameters and enhancing power distributioefficiency.

The BYFD power distributiomeasuring and controlling device integrates voltmeter, ammeter, power factor meter, voltage automatic recorder, voltage quality monitor, active energy meter, reactive energy meter , harmonic monitor, reactive compensatiocontroller and etc. It is aintelligent apparatus of high performance-price ratio and complete functions for monitoring and managing low voltage power distributionetwork.

The BYFD power distributiomeasuring and controlling device supports RS232/RS485 communicatio, and it caalso be extended for near wireless meter reading and remote BYFD data acquisitiomode. Iconjunctiowith its humanized background software, it carealize comprehensive analysis of power supply quality and statistics of power supply reliability, voltage qualificatiorate, load rate and other indexes. Iadditio, it caalso display various data lists, draw curves, print, output and analyze statistical reports.
