In recent years, the implementation of information security level protection has become a key focus across various industries in China. The power sector, given its critical role in national infrastructure, has taken proactive steps to develop industry-specific standards tailored to its unique operational and security needs. This article explores the protection requirements for information security levels within the power industry and outlines how both national basic indicators and industry-specific criteria are applied during rating evaluation processes.
The power industry encompasses not only systems related to power generation, transmission, and distribution but also includes management systems such as production and marketing. In 2005, the Electricity Regulatory Commission issued the “Regulations for the Protection of Secondary Power Systems,†marking an early step in formalizing information security practices. Subsequent guidelines, such as the “General Plan for the Protection of Power System Secondary Systems†and specific plans for dispatch centers and substations, further reinforced these efforts. As one of the first sectors to implement the national information security level protection framework, the power industry has continuously refined its approach through pilot projects and real-world application.
The power industry adopts a cautious and methodical approach to information security level protection, leveraging pilot demonstrations to identify best practices. Based on the characteristics of power systems, it has developed a set of industry-specific protection requirements that align with and often exceed national standards. For instance, the Ministry of Public Security’s 2009 guidance emphasized that key sectors should follow the “Basic Requirements for Information System Security Level Protection†while tailoring them to their unique needs. This has led to the development of the “Basic Requirements for the Protection of Power Industry Information System Security Levels,†which serve as a foundational document for the industry.
This article provides a comprehensive overview of how the power industry applies these standards in practice. It details the process of selecting and applying both general and specialized evaluation indicators during the assessment of information systems. Through case studies and practical examples, it illustrates how these standards are implemented, tested, and refined to ensure robust security measures.
As the scope of information security level protection evaluations expands, the power industry continues to adapt to new challenges posed by smart grids and emerging technologies. These advancements bring increased automation, interactivity, and digital integration, which require more sophisticated and dynamic evaluation methodologies. The ongoing development of these assessments plays a crucial role in strengthening the overall security posture of the power sector and ensuring the reliability of critical infrastructure.
Overview
A turbidity sensor, also known as a turbidity probe, is a water quality sensor used to measure suspended matter content and assess water clarity. Daruifuno's turbidity sensors and probes are based on the principle of light scattering or light transmission. They measure the intensity change of transmitted or scattered light when light passes through water, and calculate the turbidity value through a specific algorithm. This turbidity sensor and probe has the characteristics of high precision, real-time monitoring, intelligence, and durability. It is an indispensable tool in modern water quality monitoring.

Introduction to Turbidity
Turbidity refers to the degree of obstruction caused by a solution to the passage of light, including the scattering of light by suspended matter and the absorption of light by solute molecules.
Definition: Turbidity is an optical effect that characterizes the degree of obstruction caused by tiny insoluble particulate matter (such as suspended matter and colloids like silt, humus, and phytoplankton) in a solution (especially water) to the passage of light.
Principle: When light passes through a solution containing suspended particles, the particles scatter and absorb light, causing light attenuation. The magnitude of turbidity is closely related to factors such as the content, size, shape, and refractive index of the suspended particles.
Unit of Measurement: There are various units for measuring turbidity, the most common of which are NTU (Nephelometric Turbidity Unit, also known as TU), FTU (Formazine Turbidity Unit), and JTU (Jackson Turbidity Unit, a standard solution based on white clay or diatomaceous earth). Additionally, there are standard turbidity units expressed in SiO2 content.
Standard: Turbidity measurement is typically calibrated with a standard solution, such as one prepared with formazin. The measurement result obtained by measuring the scattered light principle is called 1NTU.
