Ensure Your Electrical System’s Safety with Our Reliable Transformer Testing Solutions.
Transformers are core components within power systems, whether located in substations, power grids, transmission lines, or power plants. They perform the critical task of voltage transformation. Given their high maintenance and replacement costs, regular and effective testing and maintenance are paramount to ensuring the long-term stable operation of these vital assets.
Transformer testing encompasses a series of critical procedures designed to assess the electrical insulation performance, operational status, and overall health of a transformer. These tests not only help identify potential faults but also predict equipment lifespan, thereby preventing unexpected outages and expensive repair costs.
By regularly performing transformer tests, power operators and maintenance teams can gain a comprehensive understanding of their transformers’ health, promptly identify and resolve issues, thereby significantly enhancing equipment reliability, extending their service life, and ultimately ensuring the safe and stable operation of the power system.
Transformer test equipment is essential for ensuring the safety, reliability, and performance of power and distribution transformers. These instruments are used by manufacturers, utilities, and maintenance teams to perform routine diagnostics, factory acceptance tests, and condition assessments of transformers.

Transformer Tan Delta Tester is a specialized electrical testing instrument used to assess the insulation condition of a transformer. It measures tan delta, also known as the dissipation factor (DF), Loss Angle or power factor, which indicates the dielectric losses in the insulation system.
Testing the DC resistance of transformer or motor windings helps detect issues such as shorted turns, loose connections, or damaged conductors. It ensures that the winding resistance is within design specifications for proper operation. Significant deviations may indicate overheating, corrosion, or poor manufacturing. This test also verifies the integrity of tap changers and winding connections. Besides, it is a key step in preventive maintenance and quality assurance.
Yes. Our instruments are designed and manufactured to comply with the relevant international standards, such as IEC 60076 for power transformers and IEEE C57.12. This ensures that the test methods and results are accurate, repeatable, and globally recognized, giving you confidence in your asset management decisions.
Winding resistance tester can adopt the “step current method,” which involves initially applying a low current—typically around 20% of the rated test current—to establish a magnetic field. The current is then gradually increased to the rated level (e.g., 1A, 5A, or 10A). This helps minimize the impact of the inductive energy storage process.
In addition, the tester is equipped with an automatic arc suppression circuit, which reduces the effect of back electromotive force (EMF) during current switching and prevents pointer jitter.
By enabling the “fast stabilization mode,” the tester uses intelligent algorithms to predict the final stable resistance value. When the rate of change in the measured value falls below 0.05% per second, the reading is automatically locked. These combined techniques can reduce the stabilization time from the conventional 3–5 minutes to under 1 minute for transformers rated above 1000 kVA
