Product Description

XZH TEST Three Phase Test Transformer Winding DC Resistance Tester 40A

The XHZ1340A transformer DC resistance tester is a next-generation rapid testing device that combines magnetic testing, three-phase testing, and degaussing functions. This instrument is specifically designed for measuring DC resistance in large power transformers with exceptional efficiency and accuracy.

Key Features

Simultaneous three-phase testing capability for star-connected windings (A0, B0, C0 phases)
No need to reverse test wires during operation - connect once for complete testing
Automatic magnetic assist method for faster testing of three-phase five-column low-voltage transformers
Comprehensive data display and printing of all winding test results (high, medium, and low voltage)
Automatic calculation of three-phase unbalance degree with temperature-converted resistance values
Advanced neutral point lead wire resistance testing capability
Robust back-EMF protection system
Data storage for 200 test results (expandable) with USB export capability
Designed for harsh environments with wide temperature tolerance and anti-interference features
