能夠快速檢測到干擾是電網(wǎng)安全可靠操作的先決條件。因此，對諸如電流和電壓等特定變量的監(jiān)控必須持續(xù)不間斷進行。數(shù)字式電網(wǎng)保護繼電器則用于對這些變量進行監(jiān)視控制，它們起到斷開和切換有缺陷的電纜或變壓器的作用。當電網(wǎng)保護繼電器識別到供電電纜上的錯誤時，該線路中的斷路器立即發(fā)出切斷電路的觸發(fā)信號。
作為安全測試的一部分，電網(wǎng)繼保設備需要定期測試，以確保它們能夠正常工作。為了使測試操作相對便捷和安全，EAM以往使用可插拔式連接器。一旦建立連接，需要首先通過旋轉開關將待測互感器短路，“斷路器斷開”的信號則立即終止。
事實上功能測試只有在所有步驟完成之后才能開始。由于中壓開關設備通常只安裝一個保護裝置，因此在測試期間所有保護功能都被中止。如果電網(wǎng)在執(zhí)行測試的同時發(fā)生錯誤，則保護裝置不能作出反應，因此存在嚴重的潛在危險，甚至可能會導致電網(wǎng)故障甚至系統(tǒng)組件損壞。
使用Fame進行簡化和無差錯的保護測試
為了使保護測試更簡單、安全，菲尼克斯電氣開發(fā)了Fame組合化測試系統(tǒng)。在單個連接步驟中，該系統(tǒng)無需觸發(fā)開關即可將大量必要的觸點與測試裝置進行連接。所有開關過程都通過插入測試插頭來自動啟動。待測互感器的接觸、分斷和短路的順序通過連接器指定，以確保操作正確。
