Technical Definition
Power transformer testing equipment is a specialized system designed to conduct comprehensive electrical performance, insulation state, and mechanical reliability tests on power transformers throughout their lifecycle. Based on automated control and precision measurement technologies, it enables full-item compliance testing and data-driven quality assessment, serving as an indispensable technical support for transformer manufacturing and power system safety.
Our product line covers two main series to meet diverse operational needs: Fully Automatic Distribution Transformer Testing System (NKE-DTTS-AUTO Series): A high-efficiency standard series ideal for mass production testing, featuring one-time wiring and one-click automated testing to complete 7 routine factory tests. Semi-Automatic Distribution Transformer Testing System (NKE-DTTS-SE Series): A flexible, container-integrated series suitable for medium-to-large capacity transformers and on-site deployment, supporting semi-automated testing with high precision.
Our design centers on high reliability, precision, and user-friendliness, with strict adherence to full-life cycle reliability standards to deliver stable, cost-effective solutions for industrial scenarios.
Technical Principle
Our transformer testing equipment operates on the principle of integrated automated control and precision signal measurement. The complete workflow includes: Input: Connect the transformer to the testing system with a single wiring setup, eliminating repeated connections. Processing: The system automatically activates corresponding test modules based on preset protocols, conducting insulation resistance, DC resistance, ratio, no-load, load, and voltage withstand tests. Output: Real-time data collection and analysis are performed, with test reports generated and exported automatically.
Core architecture innovations include: Automated Control Module: Enables one-click initiation of full-item tests, reducing manual intervention and operational errors. Precision Measurement Module: Delivers 0.05-class measurement accuracy, ensuring data reliability in line with international standards. Compared to traditional manual testing methods, our solutions eliminate repeated wiring, reduce testing time by over 60%, and eliminate human-induced data errors, fundamentally solving long-standing industry inefficiencies.
