TUNKIA's Electrical Steel Testing Solutions

Comprehensive Solutions for Every Stage of the Electrical Steel Value Chain

As demand for high-efficiency transformers, electric motors, and renewable energy systems continues to grow, manufacturers face increasing pressure to reduce core losses, improve energy efficiency, and maintain consistent product quality.

Meeting these challenges requires far more than individual testing instruments. From production monitoring and laboratory evaluation to advanced magnetic research, core performance verification, and instrument calibration, every stage requires accurate, reliable, and traceable measurements.

TUNKIA provides comprehensive Electrical Steel Testing Solutions that support the entire electrical steel lifecycle. Designed for steel manufacturers, transformer and motor producers, research institutes, and calibration laboratories, our solutions help customers improve quality, accelerate innovation, and build confidence in every measurement.

Solutions for Every Stage of the Industry

Electrical steel testing requirements vary across the industry, but every application shares the same objective: obtaining accurate data to support better products and better decisions.

TUNKIA offers dedicated testing solutions for each stage of the electrical steel value chain, helping customers optimize manufacturing, validate product performance, advance research, and ensure measurement traceability.

For Steel Manufacturers

Improve Process Control and Product Consistency

Consistent magnetic performance is essential for producing high-quality electrical steel. However, conventional sampling methods may not identify process variations until after production, making quality control more difficult.

TUNKIA supports both production monitoring and laboratory quality inspection through comprehensive testing solutions.

In-line Production Testing

Monitor critical magnetic properties in real time, including: Transverse Core Loss and Longitudinal Core Loss

Continuous monitoring enables manufacturers to optimize rolling and annealing processes, reduce quality fluctuations, and improve production consistency. 

Specimen Testing

Perform comprehensive laboratory evaluation of electrical steel materials, including:

• Core Loss

• Magnetic Flux Density

• Insulation Resistance

• Electrical Resistivity

• Magnetostriction

• Lamination Factor

• Coating Adhesion

• Bending Performance

Together, these measurements provide a complete understanding of material performance for quality assurance and process optimization

For Transformer and Motor Manufacturers

Validate Performance Beyond Material Properties

Excellent material properties alone do not guarantee superior equipment performance. Evaluating magnetic cores under practical conditions provides valuable insight into manufacturing quality and final product efficiency.

TUNKIA's core testing solutions support:

• Core Loss Measurement

• Volt-Ampere (V-A) Characteristic Testing

These capabilities help manufacturers verify core quality, optimize manufacturing processes, and improve the efficiency of transformers and electric motors.

For Research Institutes

Explore Magnetic Performance Under Real Operating Conditions

As electrical steel materials continue to evolve, conventional power-frequency testing is no longer sufficient for advanced research and product development.

TUNKIA supports comprehensive magnetic analysis, including:

• Harmonic Loss Analysis

• DC Bias Magnetic Performance

• Magnetic Properties under Mechanical Stress

• Full-Angle Magnetic Property Measurement

 These advanced testing capabilities enable researchers to better understand material behavior under complex operating conditions, supporting innovation in next-generation magnetic materials and electrical equipment.

For Calibration Laboratories

Ensure Accurate, Reliable, and Traceable Measurements

 Reliable testing begins with reliable calibration.

 TUNKIA provides complete calibration solutions for magnetic measurement instruments, supporting:

• Electrical Parameter Calibration

• Magnetic Parameter Calibration

• Permeameter Performance Verification

 These solutions help laboratories establish traceable measurement systems while ensuring long-term measurement accuracy, consistency, and confidence.
