In recent years, with the deepening of environmental protection concepts, green and low-carbon development has become a consensus among all sectors of society. As a traditional industrial province, Shandong has taken an important step in promoting green transformation. Have you ever thought about what natural ester insulated oil transformer is? What is the difference between it and traditional mineral oil transformers? In this context, State Grid Shandong Electric Power Research Institute recently approved the release of two local standards for natural ester insulated oil transformers, which undoubtedly adds new impetus to Shandong's green energy reform.

Firstly, let's talk about the background and importance of these two standards. According to reports, the "Technical Specification for Condition Maintenance of Natural Ester Insulated Oil Transformers" and "Technical Specification for Handover Test of Natural Ester Insulated Oil Transformers" led by State Grid Shandong Electric Power Research Institute have recently been officially approved by the Shandong Provincial Administration for Market Regulation. This is the first local standard in Shandong Province that specifies the requirements for handover testing and condition based maintenance of natural ester insulated oil transformers. Compared to traditional mineral insulating oil, natural ester insulating oil not only degrades automatically, but is also safe and harmless. It is a green and environmentally friendly insulation material with zero carbon emissions, which is more in line with the requirements of the national "dual carbon" policy.

So, what is the magical thing about natural ester insulated oil transformers that makes Shandong Province pay so much attention to them? Originally, unlike traditional mineral oil transformers, natural ester insulated oil transformers have their own characteristics in terms of handover testing. However, at present, there is a lack of unified standards for handover testing and status maintenance, which poses a hidden danger for safe operation. Taking this opportunity, State Grid Shandong Electric Power Research Institute organized a team of experts including Shandong Electric Power Equipment Co., Ltd. and 19 relevant enterprises and universities in the province to conduct in-depth research on standard policies, on-site application requirements, and technical issues. Eventually, these two important local standards were successfully formulated and released.

Next, let's uncover the mystery behind these two standards. The Technical Specification for Condition Maintenance of Natural Ester Insulated Oil Transformers specifies in detail the implementation principles of condition maintenance and the work content of condition evaluation, clarifying the maintenance standards for new and old equipment, power outage maintenance cycles, and other contents. These standards can not only effectively guide the maintenance work of natural ester insulated oil transformers, but also timely eliminate latent faults and ensure the safe operation of equipment.

The Technical Specification for Handover Test of Natural Ester Insulated Oil Transformers specifies 21 handover acceptance test items, which will provide strong guarantees for the smooth network connection of natural ester insulated oil transformers based on these technical requirements and judgment criteria. The implementation of this specification is timely and necessary to ensure the quality and safety of natural ester insulated oil transformers. Will anyone ask why the introduction of these standards is so important? Because they not only ensure the safety of equipment, but also provide strong support for promoting low-carbon development.

It is worth mentioning that the introduction of natural ester insulated oil transformers marks substantial progress in Shandong's transition to a green power industry. It is not only the pursuit of the national "dual carbon" goal, but also a contribution to the construction of a clean, low-carbon, safe and efficient modern energy system. Hey, we live in an era of intensive electricity, and the power facilities around us can be seen everywhere. You know what? Our future is closely linked to these silent technological standards.

In the future, State Grid Shandong Electric Power Research Institute will continue to promote the revision of technical standards for natural ester insulated oil transformers, and strive to promote the comprehensive application of green and low-carbon new materials such as natural ester insulated oil in the Shandong power grid. This will not only promote Shandong's innovative development in the field of green energy, but also become a demonstration of green transformation nationwide.

In short, the standardization of natural ester insulated oil transformers is not only an emphasis on equipment safety, but also another important exploration and practice of green development in Shandong Province.
