技術名稱: 多功能數位電錶

技術簡介

以全數位的方式設計電表,用以量測與分析用電狀況。彈性的接線設定,使的它適用於所有的電源系統,從單相到三相系統。以快速的即時資訊運算的技術,同時滿足時域的用電量測統計與頻域的用電品質分析。

Abstract

Multi-function digital power meter is designed by using full-digital approach, its capability is both power consumption measurement and power quality analysis. It is suit for every power system since its flexible wiring configuration setup. Not only the power usage calculation and statistic, but also the power quality analysis function are both contained since its powerful real-time calculation power.

技術規格

1.整合電錶 (Power Meter),電力品質分析儀 (PQ Monitor),與用電調節控制器 (Utility Controller)。 2.適用於所有的中,低壓電源系統(單相,雙相與三相Y/?),45~65Hz。 3.量測功能包含電流,電壓,頻率,功率(W, VAR, VA),耗能(Wh, VARh, VAh),功因,諧波分析等。 4.標準依據: IEEE Std 1459-2010, 1159-2009 and 519-1992。 5.同時記錄量測現值,最大值,需量值,最大需量值與其發生時間等用電統計資訊。 6.清析的人機界面,與簡易的可程式控制機能,適用於即時性的用電調控與保護(如契約用電保護)。 7.電壓是以直接輸入檢測,也可外加比壓器(PT)。電流檢測是使用內含的低電流比流器(CT),也可外加CT 。 8.內建MODBUS 通訊界面。

Technical Specification
