Innovation Spotlight: China Top Turns Ratio Tester Exporter Demonstrates with HV Tech at IEEE PES T&D

As global power systems move toward higher capacity, smarter monitoring, and tighter reliability standards, transformer condition assessment has become a core focus for utilities and service providers worldwide. International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role in shaping these developments by bringing together grid operators, manufacturers, and technology partners. Within this professional setting, Huazheng is drawing attention as a China Top Turns Ratio Tester Exporter by demonstrating practical transformer testing solutions in coordination with advanced high-voltage technologies at IEEE PES T&D.
A Turns Ratio Tester(https://www.huazhengtestequipment.com/turns-ratio-tester-1/) is a fundamental diagnostic instrument used to verify whether a transformer's actual winding ratio matches its design specifications. By measuring turns ratio, phase displacement, and, in some cases, excitation current, engineers can identify winding deformation, tap changer issues, or connection errors before they escalate into operational failures. As grids expand and transformers operate under higher thermal and electrical stress, accurate turns ratio testing has become an indispensable part of commissioning, preventive maintenance, and post-fault analysis.

Evolving Industry Expectations and the Value of IEEE PES T&D
IEEE PES T&D is widely recognized as one of the most influential events in the global power transmission and distribution sector. It provides a platform not only for large-scale equipment and system-level solutions, but also for specialized diagnostic tools that support daily grid operation. The growing emphasis on asset health management and lifecycle optimization has elevated the importance of reliable testing instruments that deliver consistent, traceable results in both factory and field environments.
Within this context, transformer testing equipment manufacturers are increasingly evaluated on how well their products perform in real operating conditions rather than in controlled laboratory settings alone. Demonstrations at IEEE PES T&D allow industry professionals to assess usability, measurement stability, and adaptability to diverse transformer types and voltage classes.
Turns Ratio Testing in Real-World Grid Applications
Turns ratio testing is applied across multiple stages of transformer use. During factory acceptance tests, it confirms winding accuracy before shipment. At substations, it is routinely performed after installation to ensure that transportation and assembly have not introduced mechanical or electrical deviations. During scheduled maintenance, changes in ratio or excitation current can indicate early-stage core or winding problems, supporting condition-based maintenance strategies.
For these tasks, modern turns ratio testers must balance accuracy with efficiency. Automatic testing sequences reduce human error, digital displays improve readability in outdoor environments, and data storage functions support traceability and reporting. Portability is also a decisive factor for field engineers who may need to test multiple transformers across large substations or dispersed networks within limited outage windows.
Huazheng's Turns Ratio Tester Portfolio in Practice
Huazheng Electric Manufacturing (Baoding) Co., Ltd.,(https://www.huazhengtestequipment.com/about-us/) founded in 2008, specializes in the development and production of power testing equipment, including transformer testers, oil testers, relay protection testers, high-voltage test equipment, and circuit breaker testers. Located in Baoding, China, near Beijing, the company benefits from convenient transportation links that support both domestic supply and international export operations.
Among Huazheng's representative products, the HZTTR80A Transformer Turns Ratio Tester with Excitation Current is designed for comprehensive transformer diagnostics. In addition to standard turns ratio and phase angle measurement, it supports excitation current testing, which is particularly useful for identifying abnormal magnetic conditions in transformer cores. This model is commonly applied in substations during detailed maintenance inspections of medium- and high-voltage power transformers, where engineers require deeper insight into internal conditions without dismantling equipment.
For applications that prioritize mobility and ease of deployment, Huazheng offers handheld and portable solutions such as the HZBB-10B Transformer Turns Ratio Tester and the HZBB-10B-I Portable TTR Meter. These compact devices are suited for routine inspections, commissioning tests, and service work carried out by utility maintenance teams and third-party testing companies. In addition, the HZBB-10S Handheld Transformer Turns Ratio Tester provides a lightweight solution for fast on-site verification, particularly suitable for distribution transformers and daily inspection tasks where speed and portability are critical. Their lightweight design allows technicians to move efficiently between test points, while digital measurement functions support reliable verification of single-phase and three-phase transformers in the field.
By providing both advanced multifunction testers and portable handheld models, Huazheng addresses a broad range of operational scenarios rather than assuming a single testing environment. This flexibility reflects the practical demands faced by utilities, contractors, and maintenance teams working across diverse grid infrastructures.

Quality Management, Global Reach, and Technical Collaboration
Huazheng operates under an ISO 9001 quality management system and its products carry CE certification, supporting compliance with international technical and safety standards. Quality assurance and quality control processes are integrated throughout design, manufacturing, and final inspection to ensure consistency and long-term reliability.
Since 2012, Huazheng's testing equipment(https://www.huazhengtestequipment.com/success-case/) has been supplied to customers in the United States, Brazil, Chile, Vietnam, Indonesia, South Korea, Turkey, Dubai, and South Africa. The company has accumulated experience serving state grid organizations, municipal power departments, transformer manufacturers, laboratories, substations, and power testing service providers. Participation in projects involving internationally recognized enterprises such as Ausgrid and GE has further strengthened its exposure to complex engineering requirements and global best practices.
To better support overseas users, Huazheng continues to expand its international service network and develop localized after-sales support capabilities. OEM cooperation is also available, enabling partners to integrate Huazheng's testing technology into broader system solutions.
Looking Ahead: Transformer Testing in a Changing Grid Landscape
As power networks become more interconnected and performance expectations continue to rise, transformer testing will remain a cornerstone of grid reliability and safety. While turns ratio testing is a well-established procedure, the equipment used for this purpose continues to evolve alongside digitalization and condition monitoring trends. Manufacturers that focus on practical usability, measurement accuracy, and compliance with international standards are positioned to contribute meaningful value to modern grid operations.
Through active participation in global technical exhibitions and the presentation of proven testing instruments such as the HZTTR80A, HZBB-10B, HZBB-10B-I, and HZBB-10S, Huazheng demonstrates how transformer turns ratio testers support real-world maintenance and commissioning tasks. Its role as a Chinese exporter of transformer testing equipment reflects the broader globalization of power technology and the growing demand for dependable diagnostic tools.
