微機式六相/三相繼電保護測試儀主要功能：
1、具有標準的六相電流，六相電壓同時輸出，電流 30A/相，電壓 125V/相。六相電流并聯可達 180A。既可對傳統的各種繼電器及保護裝置進行試驗，也可對現代各種微機保護進行各種試驗，特別是對變壓器差動保護和備自投裝置，試驗更加方便。
2、各種技術指標達到電力部頒發的DL/T624-1997繼電保護微機型試驗裝置技術條件的標準。
3、單機獨立運行，內置高性能工控機，主頻 300--600MHz，內存 128M，硬盤 6--12G，運行 Windows XP操作系統。
4、國內同行業首先采用進口拉絲不銹鋼面板，不銹鋼鍵盤，同時采用觸摸式鼠標，克服了軌跡球鼠標操作不靈活、容易損壞的缺點，并選用 8.4寸,分辨率為800×600的TFT真彩顯示屏,使得單機整體操作方便自如,經久耐用。
5、主控板采用 DSP+FPGA 結構,16 位 DAC 輸出,對基波可產生每周 2000點的高密度正弦波,大大改善了波形的質量,提高了測試儀的精度。
6、功放采用高保真線性功放,既保證了小電流的精度,又保證了大電流的穩定。
7、采用 USB接口直接和PC機通訊，無須任何轉接線，方便使用。
8、可連接筆記本電腦運行。筆記本電腦與工控機使用同一套軟件。
9、具備 GPS 同步試驗功能。裝置可內置 GPS 同步卡（選配）通過 RS232口與PC機相連，實現兩臺測試儀異地進行同步對調試驗。
10、配有獨立專用直流輔助電壓源輸出，輸出電壓分別為 110V（1A），220V（0.6A）。以提供給需要直流工作電源的繼電器或保護裝置使用。
11、具有(you)軟(ruan)件自較(jiao)準功能(neng)，避免了(le)要打開機箱通(tong)過調整電位器來校準精度，從而大大提高了(le)精度的穩定性。
