儀器內部自動進行量程切換，允許測量電壓、電流范圍寬，接線簡單。4. 做三相變壓器的空載、負載試驗時，儀器能自動判斷接線是否正確，并顯示三相電壓、電流的向量圖。5. 單機可以完成1000KVA以下的配電變壓器全電流下的負載實驗的測量；在三分之一額定電流下可完成3150KVA以下的配電變壓器的負載試驗的測量（在三分之一的額定電流下，儀器可換算到額定電流下的負載損耗參數）。廣州電子變壓器檢測機構全自動變比測試儀真正意義上的三相同時測量。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">下面就將常見變壓器變比測試儀在使用過程中常遇到的問題匯總：1、測試時將高低壓測試線接反，這種情況在常見變比測試儀會將儀器損壞。在一些新測試儀中加裝了保護裝置，測試線接反時會將測試回路的保險絲熔斷。2、測試值與計算值不符，接線組別與銘牌接線組別不符，可能是儀器損壞，也可能是變壓器存在問題。3、測試注意事項夾線鉗必須可靠夾緊，避免測試過程中夾線鉗掉落，在以往測試中發(fā)現，測試中夾線鉗掉落，繼而導致儀器損壞。4、測試過程中禁止觸摸被測試變壓器接線銅牌?，F場對變壓器變比是否損壞的檢測方法；1、用被檢測的變比測試儀對已經測試合格的變壓器進行復測，與合格數據進行對比。2、將高低壓側測試線鉗A-a；B-b；C-c夾住，進行測試。此時變比測量結果應該為1。部分廠家不建議用此方法測試，存在一定的爭議。</p><p style="text-indent:25px">變壓器低電壓短路阻抗測試儀，適用于電力變壓器（單相或三相）出廠、大修、預試以及交接試驗中低電壓負載阻抗測試。常規(guī)試驗項目中的基本項目，其原理是在現場對電力變壓器進行短路阻抗（%）測試，并與銘牌值或出廠值進行比較，能發(fā)現出廠試驗后經運輸、安裝和運行中嚴重故障電流等所造成的繞組位移、變形等缺陷。變壓器低電壓短路阻抗測試儀用于現場和試驗室條件下對35KV級及以上主變壓器進行低電壓短路阻抗測量的儀器。該儀器設計精巧，性能優(yōu)越，內部采用較新型的單片機測試技術及數字信號處理技術，測量數據準確；外部采用7寸觸摸彩色液晶顯屏，顯示中文操作菜單，觸摸操作更便捷，同時配備熱敏打印機和存儲功能，方便數據的打印和存，將所需導出的數據可通過USB轉存到計算機；儀器體積小，便于現場使用攜帶；本儀器輸入參數，便可進行單、三相測試并自動計算變壓器阻抗誤差百分比，測試結果非常直觀，是現場測試變壓器有無繞組變形的快速測試儀器。檢查分接開關的位置是否正確。</p><div

style="text-indent:25px">變壓器幾乎在所有的電子產品中都要用到，它原理簡單但根據不同的使用場合（不同的用途）變壓器的繞制工藝會有所不同的要求。變壓器的功能主要有：電壓變換；阻抗變換；隔離；穩(wěn)壓（磁飽和變壓器）等，變壓器常用的鐵心形狀一般有E型和C型鐵心。一般降壓變壓器一次繞組的電阻值為幾十至幾百歐，二次繞組為幾歐至幾十歐，這點要做到心中大致有數，為選萬用表的量程提供參考，一般選用萬用表的R×1或R×10檔，分別測一次繞組和二次繞組，查看有無斷路和短路問題，這個方法有個缺點就是，無法檢測出局部短路問題，這個缺憾可以通過通電檢查彌補。自動記錄試驗的日期、時間利于實驗結果的保存、管理。安微實驗時電源變壓器</p><p
