為何不同的電錶量測的電壓或電流值不一樣?

可以考慮兩個因素: 1)True RMS, 2) Scan rate. 1) 使用的電錶是不是True RMS的量測方式,還是用average responding, 或peak averaging。在電壓、電流波型失真時,True RMS還是可以精確的量測電壓、電流。非true RMS的電錶,針對非正弦波形,會量測偏高或偏低。 2) 針對快速變動的負載,量測值的scan rate以及錶頭螢幕的更新率需要考慮進去。如果電錶量測值以及螢幕更新率不夠快,會無法呈現負載變化中,最高的數值。如果電錶有高速模組,比如ION7650、PM8000,可以從軟體來看負載的快速變化。

PM5330的Tariff功能底下,Del 與 Rec 是什麼意思?

PM5330 Tariff Del & Rec Function Q: 為什麼PM5330的tariff電能瀏覽的畫面下,會有Del刪除、Rec記錄的指令? 這樣子是不是可以任意修改電能的記錄值? A: PM5330的tariff頁面瀏覽底下,Del與Rec的功能只的是傳遞(delivered)與接收(recieved)的電能。他們分別會顯示電錶接收的有功、無功、與視在電能,以及電錶傳遞出去的有功、無功、與視在電能。詳PM5300系列使用手冊第46頁。

什麼樣的漏電斷路器適合電路中有變頻器?

由於漏電保護器, 是利用 零相CT (ZCT) 去偵測, 變頻器的特性容易讓漏電保護器 誤動作而跳脫, 建議斷路器下加上漏電模組, 感度電流可以調整至 200mA 以上

ATV320變頻器煞車電阻如何接線?參數如何設定?

ATV320連接煞車電阻: ATV320••••C變頻器煞車電阻接線端子為P0和PB,ATV320••••B變頻器煞車電阻接線端子為PBe和PB,PA+、PC-為直流母線端子,PA+、PC-不需要接線。 注意:PO和PA之間的短接片不要拆掉。 ATV320變頻器連接煞車電阻後,需要設定以下參數來啟用煞車功能: CONF->FULL->FUn-->rPt-->brA=nO(出廠設定為yes), ATV320出廠預設的停車類型stt是斜坡停車(rmp),注意停車類型不能設定為nst(自由停車),否則煞車電阻在停車時不會投入使用。 ATV320菜單結構如下:
