Profile:

The KDZD2015L addresses a critical yet often overlooked step in transformer maintenance: residual flux removal. Traditional demagnetization takes up to 30 minutes with inconsistent results—but the KDZD2015L completes the process in as little as 2–3 minutes with over 90% effectiveness. Its compact, lightweight design (5 kg), intuitive Chinese-language interface, and compatibility with existing DC resistance test leads make it ideal for field engineers. Whether performing fine, standard, or rapid demagnetization, this unit delivers consistent, reliable performance across all voltage levels and transformer sizes.

Features:

Features

DC Variable-Frequency Decay Principle – ensures deep and uniform demagnetization
Single-Phase Operation – demagnetize just one phase to effectively remove core remanence
Ultra-Fast Process – reduces demagnetization time from 30 min to ≤3 min
High Efficiency – achieves >90% remanence reduction per cycle (vs. ~80% traditionally)
Four-Wire Connection – directly uses existing DC resistance test cables for seamless workflow
Real-Time Progress Display – clear Chinese UI shows 0–100% demagnetization status
Field-Ready Design – only 5 kg, compact size (32×26×25 cm), rugged for on-site use
