Main Classifications

• NKE-DTTS-AUTO Series: Fully automated high-precision series, suitable for mass transformer production factories, featuring one-time wiring and one-click full-item testing with 0.05-level accuracy.
• NKE-DTTS-SE Series: Semi-automated flexible series, suitable for small-batch production and on-site testing scenarios, supporting vehicle-mounted and containerized designs for easy mobility.

Design Philosophy

Our equipment is designed with precision, efficiency, safety, and ease of operation as core principles, adhering to full-life cycle reliability standards to provide stable, low-maintenance, cost-effective solutions for industrial scenarios.

Technical Principles

The core working principle of our turn ratio transformer testing equipment is based on electromagnetic induction. The complete implementation link is as follows:

1. Input a standardized test signal to the transformer’s primary winding to generate a magnetic field in the core.
2. Collect voltage signals from both high and low voltage windings through high-precision acquisition modules.
3. Automatically calculate turn ratios and winding groupings via intelligent computing modules, and generate standardized test reports.

Core Architecture & Innovative Design

• High-Precision Signal Acquisition Module: Equipped with 16-bit AD converters, ensuring signal sampling error is less than 0.05% for accurate data capture.
• Intelligent Data Processing Module: Integrates automated calculation and report generation functions, eliminating manual recording errors and improving data traceability.

Comparison with Traditional Solutions

Unlike traditional manual testing methods that require repeated wiring and manual calculation, our automated equipment completes full-item testing with one-time wiring, reducing test time by 70% and eliminating human-induced data errors, effectively solving long-standing industry pain points.
