Description
XHZ1340A The Ultimate Transformer Tester for DC Resistance Measurement of Large Power Transformers
The XHZ1340A transformer DC resistance tester is a new generation of rapid testing equipment that integrates magnetic testing, three-phase testing, and degaussing functions. This advanced instrument is specifically designed for measuring the DC resistance of large power transformers with exceptional precision and efficiency.
Key Features
  • Simultaneous connection of high and low voltage current potential test wires without need for reversal during testing
  • Three-phase simultaneous testing capability for star-connected windings (A0, B0, C0 phases) significantly reduces testing time
  • Automatic magnetic assist method for faster testing of three-phase five-column low-voltage internal corner-connected transformers
  • Comprehensive data display and printing of all test results for high, medium, and low voltage windings
  • Automatic calculation of three-phase unbalance degree with optional printing of resistance values converted to rated temperature
  • Innovative testing sequence that solves the neutral point lead wire resistance measurement challenge
  • Advanced back-EMF protection for enhanced safety
  • Permanent storage for 200 test datasets (expandable) with USB export capability for computer analysis
  • Robust design featuring wide temperature tolerance, high accuracy, shock resistance, anti-interference, and portability
