Electricity is one of the indispensable energy sources in modern society. With the growth of population, the acceleration of urbanization process, the improvement of industrialization level and living standards, the global demand for electricity would continue to grow.

According to Shangpu Consulting Group Co,Ltd, the Global electricity demand would grow by 1.5% per year between 2022 and 2030, reaching 27,000 terawatt hours by 2030.

The transformers are one of the essential components in the power system. With the growth of electricity demand, the power system also needs to be continuously expanded and transformed to improve the reliability and efficiency of power supply, which undoubtedly provides a huge market space for the transformers. According to the “Report of the Chinese transformer industry market demand and investment planning analysis between 2022 and 2026” released by the Newsijie Industrial Research Center, the global transformer market size in 2021 was about $8.69 billion; from 2018 to 2021, the global transformer market continues to grow, with an average annual compound growth rate of 4.4%.

China is one of the world's largest producers and consumers of transformers, with numerous transformer enterprises and products.Among them, Jiangyin Spark Electronic Technology Co., Ltd. which established in 1995 has been committed to the research, development, production and sales of current transformers for almost 30 years. Company products include low voltage DC current transformer; indoor busbar type split core current transformer; indoor cable type split core current transformer; outdoor cable type split core current transformer; ring type split core current transformer; residual current type split core current transformer; Rogowski coils; hall sensor series; transmitter series; residual current closed current transformer; cable type closed current transformer; secondary transformer-current voltage transformer; secondary transformer-micro current transformer; three-phase multi-function intelligent instrument; energy, equipment management solutions and services. The majority of the products have passed the UL, CE, ETL and other international certifications, products are sold to domestic and abroad.

In recent years, Chinese transformer industry has benefited from the growth of domestic and foreign market demand, in particular, State Grid has increased the investment in the construction and transformation of transmission and distribution network, and promoted the implementation of smart substation, smart distribution network and other projects, providing a broad application space for the transformer. According to the data from Shangpu Consulting Group Co,Ltd, in 2022, the market size of Chinese transformer industry would reach 13.306 billion Chinese yuan, and the annual size of Chinese transformer market is expected to reach 15 billion yuan in 2023, accounting for 15.6% of the global market.

Transformer is a general term of voltage transformer and current transformer. Its function is to convert high voltage or high current into standard low voltage and standard small current, in order to realize the purpose of instrument measurement and protect the line.

Among them, the split core current transformer is a sensor used to measure the current in the AC circuit. Compared with the traditional fixed current transformer, the split core current transformer has the advantages of smaller size, lighter weight and more convenient installation. However, there are many kinds of split core current transformer products but no unified standard. The safety and stability during production and use are not guaranteed.

Therefore, it is necessary to develop relevant technical specifications to protect the personal safety of operators and maintainers to the greatest extent, provide technical support for the domestic power and electrical equipment industry, and help the healthy development and technological progress of the transformer industry.

According to the relevant provisions of the “China International Association for the Promotion of Science and Technology Standardization Committee group standards Management Measures”, after the China International Association for the Promotion of Science and Technology Standardization Committee and relevant experts’ technical review, approved the “split core current transformer safety requirements” group standard formulation plan, the plan number is: CI2023424, this standard is proposed by Jiangyin Spark Electronic Technology Co., Ltd. and associated by China International Science and Technology Promotion. At present, the exposure draft of the group standard  “split core current transformer safety requirements” has been approved and waiting for the final audit.

This group standard specifies the safety requirements, testing methods and quality classification of split core current transformers, including the scope of application of the standard, normative reference documents, term definitions, abbreviations, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage and so on.

In order to make this group standard more scientific, advanced and operable, there is an urgent need for relevant units to discuss together and form technical specifications generally recognized by the industry. In this regard, we sincerely invite relevant units and industry experts with practical experience or interest to actively participate in the review of our standards.

If you are the experts or company representatives who interested in participating in the standard formulation and audit of the group standard, please contact us as soon as possible, the audit would be organized in the early 2024.
