This technical overview introduces transformer testing systems developed by Qingdao Nanke International Electric Co., Ltd., a leading supplier in electrical equipment testing with a global client base including Siemens and Eaton. Our systems address key industry pain points: low testing efficiency, inaccurate manual data, and non-compliant procedures. Designed to meet IEC 60076 standards, our core innovation lies in one-time wiring fully automatic testing, enabling 7-item integrated verification. To date, we have served over 200 transformer manufacturers across the U.S., Mexico, Indonesia, and other countries, delivering reliable solutions for factory testing, third-party certification, and grid acceptance.

Technical Definition & Classification

Transformer testing systems are specialized equipment for comprehensive electrical performance, insulation, and reliability tests on power transformers throughout their lifecycle, based on automated control and precision measurement technologies. As a critical component in transformer quality assurance, these systems ensure compliance with international standards and support safe power grid operation.

Our product portfolio includes two core series and customized services: 1. NKE-DTTS-AUTO Fully Automatic Series: High-precision (0.05-class) systems for 500kVA to 10000kVA transformers, featuring one-time wiring and automatic report generation, ideal for batch factory testing. 2. NKE-DTTS-SE Semi-Automatic Series: Containerized systems for 5000kVA to 30000kVA transformers, suitable for overseas on-site deployment and medium-to-large capacity testing. We also offer turnkey test station design and construction services covering 6–1000kV voltage levels.

Core Technical Advantages

1. One-Time Wiring Fully Automatic Testing: Patented technology eliminates repeated wiring, reducing operation time by 80% and labor costs by 60%. The system automatically executes 7 test items and generates standardized reports, ensuring data consistency and traceability.

2. High Precision & Global Compliance: With 0.05-class measurement accuracy, our systems meet IEC 60076 standards, producing internationally recognized test reports. This ensures compliance with global regulatory requirements and avoids acceptance risks for clients.

Key Application Scenarios

1. Transformer Manufacturers: Batch factory testing to improve production efficiency and ensure product quality. Our systems have helped clients increase testing speed by 300% while reducing manual errors.

2. Third-Party Testing Labs: Accurate, compliant testing to deliver credible certification reports accepted by global markets.

3. Power Grid Companies: Acceptance testing to verify transformer reliability and reduce post-installation maintenance risks.

International Standards & Compliance

All our systems are designed and tested to meet IEC 60076 and IEEE C57.12.00 standards. Products comply with UL/CE requirements, and we provide third-party test reports, factory inspection certificates, and compliance documents upon request.
