Kini usa ka high-integration, multi-functional nga precision testing instrument gihisgutan alang sa comprehensive electrical performance detection sa power transformers, distribution transformers, oil-immersed transformers, ug dry-type transformers. Ang iyang core function mao ang pag-integrate sa 8+ key test items sa usa ra ka device, naghimo og one-stop testing sa transformer winding DC resistance, turns ratio & connection group, no-load/load loss, insulation resistance, withstand voltage, OLTC dynamic performance, ug optional winding deformation (FRA) test, walay repeated wiring.
Prinsipyo sa pagtrabaho: I-connection ang device sa high-voltage side, low-voltage side, neutral point, ug control circuit sa transformer usa ra. Ang embedded industrial computer nag-control sa relay matrix aron mobag-o ang test circuits automatik, mogenerate og standard test signals (high voltage/large current), mag-collect og real-time data pinaagi sa 16-bit high-speed ADC sampling module, mag-process sa data pinaagi sa DSP digital signal processing technology, ug mag-compare sa IEC 60076, IEEE C57, ug GB 1094 standards aron mohimo og compliant ug traceable nga test report. Nag-integrate kini og multiple test functions aron makalimpyo sa trouble sa pag-switch sa split instruments, nakapahigayon og dako sa testing efficiency.
