Kdzr-s40a Transformer Dc Resistance Tester (hereinafter Referred To As Dc Resistance Tester) Is The Latest Generation Product Of Transformer Dc Resistance Measurement. It Is Optimized For Measuring The Dc Resistance Of Three-phase Winding Of Large Capacity Transformer.

 

The Three-phase Winding Dc Resistance Of The Transformer Can Be Tested At The Same Time.

 

The Dual Power Supply Structure Is Adopted To Connect The Winding Of The Transformer Yn With Tapping To Realize Three-phase Simultaneous Power On. The Measurement System Adopts Independent Three-channel Current Sampling And Independent Three-channel Voltage Sampling, And Simultaneously Measures And Displays The Three-phase Resistance Value And Three-phase Unbalance Rate.

The On Load Voltage Regulating Transformer Can Directly Adjust The Tap Changer Without Discharging, Which Greatly Shortens The Working Time And Solves The Problem Of Long Time-consuming Dc Resistance Test Of Each Tap Winding Of Power Transformer. The Measurement Time Is One Third Of That Of Traditional Single-phase Measurement.

 

The Dc Resistance Meter Adopts Large Screen Lcd, With Full Chinese Graphical Interface, Which Is Clear And Intuitive, And The Operation Is Very Simple.

It Is Equipped With Panel Printer And Large Capacity Nonvolatile Memory, Which Can Conveniently Store And Print Measurement Results. The Test Data Is Stable, Fast And Repeatable. It Is The Best Choice For On-site Measurement Of Transformer Dc Resistance.

 

Kdzr-s40a Transformer Dc Resistance Tester Is A Necessary Test Item For The Factory Test, Installation, Handover Test Of Semi-finished Products And Finished Products In Transformer Manufacturing And Preventive Test Of Power Department.

It Can Effectively Find The Manufacturing Defects Such As Material Selection, Welding, Loose Connection Parts, Missing Strands, Broken Wires And Other Hidden Dangers After Operation Of Transformer Coils. In Order To Meet The Needs Of Rapid Measurement Of Transformer Dc Resistance, The Instrument Adopts A New Power Supply Technology, Which Has The Characteristics Of Small Volume, Light Weight And Large Output Current.

 

The Whole Machine Is Controlled By A Single Chip Microcomputer, Which Automatically Completes The Functions Of Self Inspection, Data Processing And Display, And Has The Functions Of Automatic Discharge And Discharge Indication. The Instrument Has The Advantages Of High Precision And Simple Operation, And Can Realize The Rapid Measurement Of Transformer Direct Resistance.
