Product Description

■ Product Overview

This instrument is a specialized device designed to eliminate residual magnetism in large power transformers. It features both demagnetization and demagnetization‑verification functions, playing a critical role in protecting transformers from the impact of inrush currents, ensuring safe commissioning, and extending transformer service life.

Employing advanced and rational composite current technology, this method not only rapidly demagnetizes power transformer current transformers but also quantifies residual magnetism detection. Residual magnetism measurement and demagnetization are performed automatically in a single step. For three-phase transformers, demagnetization of just one phase is sufficient, further saving time and enhancing efficiency.

■ Key Features

An advanced composite current demagnetization method is employed, resulting in minimal current surges during the demagnetization process.

High degaussing efficiency , For a three-phase transformer, de-energizing just one phase is sufficient, significantly saving time.

It is equipped with both manual and automatic degaussing.

It features both initial remanence detection and post‑demagnetization remanence measurement, allowing demagnetization and remanence quantification to be performed with a single wiring connection.

The demagnetization progress is displayed as a clear, intuitive percentage and a progress bar, with the residual magnetization rate quantified.

Wiring is simple; demagnetization can be performed directly using the DC resistance test leads.

Digital current regulation is employed, ensuring high precision in current control.

Adopt 5 Control via a color touchscreen, making operation even easier; the system interface can be switched between Chinese and English.

Test results are automatically stored, with complete records of data before and after degaussing—no manual storage required.

The report can be printed directly and saved to… U During trading.

The analysis software is highly user-friendly and intelligent; once the parameters are set, all measurements can be completed with a single button press.
