电能质量监控系统
(PQMS)

Summary

PQMS (Power Quality Monitoring System) analyzes the primary causes of power quality decline and suggests solutions for this problem by gathering power quality information from the PQ meter installed in major power facilities and analyzing the information in real time.
In particular, this is a useful system for production facility systems requiring a high quality of power.

Features

• - On / Off Line electric quality analysis
• - Interface including the user color-setting for each PQ event type
• - Visual analysis using various charts and graphs
• - Detailed analysis using various graph tools
• - Real time trend (option) analysis by using the real time data and graphs
• - Record trend (15 minutes up to / minimal / average value) and PQ event storage and management
• - PQ event statistical report
