Profile:
KDKC-2020 is a comprehensive OLTC tester that uses computer-controlled measurement circuitry to analyze conversion parameters. It features a 32-bit microprocessor and a high-speed A/D converter (400kHz sampling rate), capable of acquiring waveforms at sampling rates of 10-30kHz. An 800×480 color touchscreen interface provides an intuitive user experience, and the internal memory can store 1000 waveforms, with support for exporting via USB/USB flash drive. It supports Y0/Y/Δ transformer connections, eliminating the need for resistor conversion, and generates Word documents for easy data management.
Features:
1. Tests Y0, Y, and Δ type transformers with direct resistance display (no conversion required);
2. Intelligent data analysis automatically identifies and marks faults within transition waveforms;
3. Waveform display automatically adjusts resistance and time amplitude based on sampled data;
4. Supports both with-winding and without-winding measurement modes;
5. Four-terminal wiring method provides high-precision resistance measurement without lead compensation;
6. Continuous testing capability during measurement saves transformer outage time;
7. Generates Word reports for convenient data management and querying;
8. Computer-controlled operation with external 800×480 color LCD touch screen;
9. High-speed printer with external mouse support for easy operation;
10. Internal storage for 1000 data sets plus external USB drive saving capability.
