Description
Product Description
20A Low Resistance Ohmmeter for Transformer High Accuracy Automatic Digital Winding Resistance Meter

General Information:
This Portable Lithium Battery Transformer DC Resistance Tester is a field-oriented testing instrument for measuring DC resistance of medium and low voltage transformer windings (10kV-35kV). Designed for routine maintenance, emergency fault diagnosis and handover inspection in substations, power distribution stations and industrial workshops, it integrates a high-capacity lithium battery and constant current source technology, realizing cable-free operation in field without external power supply. It accurately tests phase resistance and interphase resistance of oil-immersed/dry-type distribution transformers, providing reliable data for judging winding connection faults and contact resistance abnormalities.
Features:
  • Ultra-High Measurement Accuracy: Resistance accuracy up to ±0.05% FS, meets the testing requirements of high-end power transformers and precision inductive equipment.
  • Multi-Current & Wide Range: 10 automatic switching ranges, max test current DC 20A, suitable for transformers of all voltage levels and capacities.
  • Automatic Calibration & Zeroing: Built-in standard resistance calibration module, supports automatic zero and full-range calibration for long-term measurement stability.
  • Professional Data Analysis: Automatically calculates unbalance rate, supports historical data trend analysis and standard value comparison for fault deep mining.
  • Rich Communication Interfaces: RS485, Ethernet and USB 3.0, supports PC upper computer software connection and remote centralized control.
