Product Description
Product Overview

The Digital Transformer Winding Resistance Tester is designed for accurate DC resistance measurement of transformer windings.

One important factor affecting winding resistance is temperature. The resistance of copper and aluminum conductors changes with temperature, making direct comparisons between measurements taken under different temperature conditions potentially misleading.

This instrument can provide resistance temperature conversion according to the selected winding material and reference temperature, where this function is available.

It helps engineers compare measurement results under consistent reference conditions and maintain more organized transformer testing records.

Main Testing Functions
  • High-resolution DC resistance measurement.
  • Multiple test current ranges.
  • Copper winding temperature conversion.
  • Aluminum winding temperature conversion.
  • Reference temperature setting, where supported.
  • Single-phase and three-phase measurement.
  • Automatic resistance unbalance calculation, where equipped.
  • Digital measurement display.
  • Data storage and export.
  • Optional automatic demagnetization.
Applications
  • Power transformer manufacturing.
  • Distribution transformer inspection.
  • Transformer maintenance and overhaul.
  • Electrical testing laboratories.
  • Transformer quality control departments.
  • Power engineering commissioning.
Addressing Common Measurement Challenges
Ambient temperature affects resistance readings

Temperature conversion helps engineers compare resistance measurements using a common reference temperature.

Winding materials have different temperature coefficients

The instrument should allow appropriate material selection where temperature conversion is supported.

Historical test data needs to be compared

Consistent temperature reference conditions make historical measurement analysis more meaningful.

Quality inspection needs reliable records

Digital storage and export help maintain measurement documentation.

Frequently Asked Questions
Q1: Why is transformer winding resistance temperature dependent?

The electrical resistance of conductor materials changes with temperature. Copper and aluminum have different temperature coefficients.

Q2: Can the instrument convert resistance to a reference temperature?

Yes, if the selected model supports temperature conversion and the required winding temperature information is provided.

Q3: Does the tester support both copper and aluminum windings?

Models with material selection can provide different conversion coefficients for copper and aluminum.

Q4: What is the purpose of temperature conversion?

It allows measurements taken at different temperatures to be compared at a common reference temperature.

Q5: Does temperature conversion replace accurate temperature measurement?

No. Reliable conversion requires correct input temperature and material information.

Q6: Can the instrument store converted resistance values?

Data storage capabilities depend on the model and its software configuration.
