It is a high-integration, multi-functional precision testing instrument designed for comprehensive electrical performance detection of power transformers, distribution transformers, oil-immersed transformers, and dry-type transformers. Its core function is to integrate 8+ key test items into one device, realizing one-stop testing of transformer winding DC resistance, turns ratio & connection group, no-load/load loss, insulation resistance, withstand voltage, OLTC dynamic performance, and optional winding deformation (FRA) test, without repeated wiring.
Working principle: Connect the device to the transformer’s high-voltage side, low-voltage side, neutral point, and control circuit once. The embedded industrial computer controls the relay matrix to automatically switch test circuits, outputs standard test signals (high voltage/large current), collects real-time data through a 16-bit high-speed ADC sampling module, processes data with DSP digital signal processing technology, and compares it with IEC 60076, IEEE C57, and GB 1094 standards to generate a compliant and traceable test report. It integrates multiple test functions to avoid the trouble of switching between split instruments, greatly improving testing efficiency.
