Lucyelec Test Equipment Transformer Winding Resistance Meter

ZSR10C Handheld Transformer Winding Resistance Meter supplied by Baoding Lucyelec Test Equipment Co., Ltd.

DC resistance measurement of transformers is an essential test item in manufacturing processes (semi-finished/finished product inspections), installation, overhauling, tap changer adjustments, acceptance tests, and preventive maintenance tests conducted by power utilities. This test verifies:
○ Welding quality of winding joints
○ Presence of inter-turn short circuits
○ Proper contact of tap changer positions
○ Alignment between actual and indicated tap positions
○ Integrity of leads and parallel conductors

Features and Advantages: 1.High output currents 2.Repeatable results 3.Strong anti-interference capabilities 4.Comprehensive protection functions 5.Automated control via high-speed microcontroller 6.Automatic discharge with audible alerts 7.High precision and user-friendly operation

Usage: The winding resistance tester is used for checking the welding quality of the winding joints and whether the windings have inter-turn short circuits, check whether the contact of each position of the voltage tap switch is in good condition, whether the actual position of the tap changer matches the indicated position, whether the lead wire is broken, and the multistranded wire is wound in parallel. Whether there is stock breakage, etc.
