Ciri-ciri
Sistem eksperimen boleh mengesan transformator pengagihan, substesen kotak gaya Amerika, dan substesen kotak gaya Eropah.
Satu bekalan wayar dapat menyelesaikan projek ujian seperti rintangan langsung, nisbah transformasi, switch bawa beban, ujian tanpa beban, ujian bawa beban, tegangan tahanan induksi, ujian peningkatan suhu, dll. Ia juga boleh melakukan ujian automatik seperti isolasi, kerugian dielektrik, tegangan tahanan arus kuasa, rintangan urutan sifar, dll.
Sistem ujian dilengkapi dengan peranti penukar voltan tinggi 20kV dan peranti penukar arus besar 5000A yang cepat, yang boleh menyelesaikan ujian tanpa beban, bawa beban, rintangan urutan sifar, dan peningkatan suhu secara automatik. Peranti output voltan tinggi boleh diperluas untuk memudahkan bekalan wayar sampel ujian.
Sistem eksperimen dilengkapi dengan peranti ujian kesalahan khusus, yang boleh menganalisis kesalahan ujian secara kuantitatif dan mendapatkan hasil ujian yang tepat.
Sistem eksperimen mempunyai skrin perlindungan paparan aksara Cina LED, yang boleh memaparkan status kerja sistem pada bila-bila masa untuk memastikan keselamatan kakitangan ujian.
Sistem eksperimen mempunyai keupayaan teknologi maklumat dan menyelesaikan pertukaran data melalui sambungan sistem pengurusan grid dan platform awan.
