Ito ay isang mataas na naka-integrate, multi-functional na precision testing instrument na disenyo para sa comprehensive na electrical performance detection ng mga power transformers, distribution transformers, oil-immersed transformers, at dry-type transformers. Ang pangunahing function nito ay ang pag-integrate ng 8+ key test items sa isang device, na nagpapahintulot ng one-stop testing ng transformer winding DC resistance, turns ratio & connection group, no-load/load loss, insulation resistance, withstand voltage, OLTC dynamic performance, at optional winding deformation (FRA) test, nang walang repeated wiring.
Prinsipyong Paggamit: Konektahan ang device sa high-voltage side, low-voltage side, neutral point, at control circuit ng transformer nang isa lang. Ang embedded industrial computer ay nagkokontrol ng relay matrix upang awtomatikong mag-switch ng test circuits, lumilikha ng standard test signals (high voltage/large current), kumukolekta ng real-time data sa pamamagitan ng 16-bit high-speed ADC sampling module, nagproseso ng data gamit ang DSP digital signal processing technology, at kinokompara ito sa IEC 60076, IEEE C57, at GB 1094 standards upang lumikha ng compliant at traceable test report. Ito ay nag-integrate ng maraming test functions upang maiwasan ang problema ng pag-switch sa pagitan ng split instruments, na malaking nagpapabuti sa testing efficiency.
