As a leading global supplier in the electrical and electronic manufacturing sector, we specialize in transformer testing systems and have served over 200 enterprises worldwide, including international giants like Siemens and Eaton. Our no-load transformer testing equipment addresses core industry pain points such as low testing efficiency, manual data inaccuracies, and non-compliance with international standards, featuring one-time wiring fully automated testing technology that adheres to IEC 60076, ISO 9001, and other global standards. Currently, we do not maintain dedicated overseas warehouses, but offer direct shipping from our China-based manufacturing facility with full customs clearance support, ensuring on-time delivery to regions including the US, Mexico, Indonesia, Korea, and Thailand.

Technical Definition

No-load transformer testing equipment is a specialized system designed to measure no-load loss, excitation current, and core performance of power transformers, verifying insulation integrity and operational reliability throughout the asset lifecycle. Based on digital signal processing and automatic control technology, it enables efficient, standardized testing critical to transformer manufacturing and grid safety. We offer two main product series: the fully automated NKE-DTTS-AUTO series, ideal for high-volume transformer manufacturers requiring batch testing, and the semi-automated NKE-DTTS-SE series, suitable for on-site or mobile testing scenarios. Our design prioritizes high precision, full automation, and compliance with international standards to deliver stable, cost-effective solutions.

Technical Principle

The core working principle of our no-load transformer testing equipment relies on digital signal processing and closed-loop automatic control systems. The operational flow includes three key steps: first, the system automatically identifies transformer parameters after a single wiring connection; second, it applies calibrated test voltage and collects real-time data with high precision; third, it analyzes data against IEC 60076 standards and generates compliant test reports. Our innovative architecture includes an Automatic Control Module that enables one-click testing without manual intervention, and a Data Acquisition & Analysis Module that ensures 0.05-class measurement accuracy and traceable data records. Compared to traditional manual testing, our solution eliminates repeated wiring, reduces human error by 90%, and cuts testing time by 80%.

Technical Parameters & Specifications

All parameters are tested strictly in accordance with IEC 60076 standards, with clear test conditions and tolerance controls. Key specifications include:
- Core Measurement Performance: 0.05-class accuracy, compatible with transformer capacities from 500kVA to 10,000kVA and voltage levels up to 500kV;
- Electrical Characteristics: Test voltage output up to 200kV, meeting international insulation testing requirements;
- Environmental Adaptability: Operates in temperatures ranging from -10°C to 50°C, suitable for both factory and on-site testing scenarios.
Customized parameters are available to meet specific customer requirements.

Technical Advantages & Differentiation

Our no-load transformer testing equipment offers two core, verifiable advantages over conventional solutions. First, fully automated one-time wiring testing: supported by our proprietary automatic control algorithm and ISO 9001-certified manufacturing processes, this feature reduces labor costs by 70% and increases testing efficiency by 80% compared to manual methods. Second, high precision and compliance: with 0.05-class measurement accuracy and full adherence to IEC 60076 standards, our equipment ensures products pass international compliance tests, reducing acceptance risks for global customers.

International Standards & Compliance Certifications

All our equipment is developed, manufactured, and tested in strict accordance with international standards, including IEC 60076 for transformer testing, ISO 9001:2015 (quality management), ISO 14001:2015 (environmental management), and ISO 45001:2018 (occupational health and safety). We hold valid certifications including national high-tech enterprise status, CNAS testing capability recognition, and customs import-export registration, ensuring full compliance with global market requirements. We can provide third-party testing reports, factory inspection documents, and compliance declarations upon request.
