Product 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
