Technical Definition

Partial discharge transformer testing equipment is a professional device for detecting insulation defects and latent faults in power transformers, based on electrical signal collection and intelligent analysis technology, which can realize full-item performance testing and early fault warning under various operating conditions. As a core solution in the electrical manufacturing industry, it has become an indispensable technical support for ensuring the safe and stable operation of power systems. Our equipment covers two main series: the NKE-DTTS-AUTO fully automatic series, designed for high-efficiency batch testing with one-time wiring and full-process unmanned operation; and the NKE-DTTS-SE semi-automatic series, suitable for medium and large capacity transformers with containerized design for easy overseas deployment. Our product design is centered on high precision, automation, and compliance, strictly following full-life cycle reliability standards to provide stable, cost-effective solutions .

Technical Principle

The core working principle of our equipment is based on high-precision partial discharge signal collection and AI-powered data analysis. The complete workflow includes three steps: first, collect partial discharge signals and electrical performance data from the transformer through specialized sensors; second, process and analyze the data using intelligent algorithms to identify insulation defects and fault risks; third, automatically generate standardized test reports compliant with international standards. Compared with traditional manual testing schemes, our equipment eliminates repeated wiring and manual data recording, reducing human error by over 90% and improving testing efficiency by 400% .

Key Technical Parameters

All parameters are tested strictly according to international standards, and we provide full parameter test reports for each batch .
