Introduction
GB/T 16895 (all parts) sets forth safety precautions for low-voltage electrical installations in general installations or locations and in special installations or locations.
Requirements for the selection, installation, inspection, and functionality of electrical equipment. It provides positive guidance for the safety of low-voltage electrical installations.
GB/T 16895 consists of six parts.
Part 1.Basic Principles, General Characteristic Assessment, and Definitions. Determining safety for the design, installation, and inspection of low-voltage electrical installations.
Rules are in place to prevent harm to people, livestock, and property during the installation and use of low-voltage electrical installations, and to ensure the safety of electrical installations.
Install and run correctly.
---Part 4.Safety Protection. This includes sub-parts 4-41, 4-42, 4-43, and 4-44, which respectively address the safety precautions taken during the installation and use of electrical equipment.
The process may involve four types of electrical hazards. electric shock, thermal effects, overcurrent, voltage interference, and electromagnetic interference. Specific safety measures are proposed for each of these hazards.
Protection requirements.
---Part 5.Selection and Installation of Electrical Equipment. Contains sub-parts 5-51, 5-52, 5-53, 5-54, 5-55, and 5-56, intended to be based on...
Equipment functionality and installation environment, including cabling systems, isolation, switching and control equipment, grounding configuration and protective conductors, and low-voltage power generation.
Requirements are set forth for the selection and installation of electrical equipment, including electrical equipment, auxiliary equipment, and safety facilities.
---Part 6.Inspection. Specific requirements are set forth for the preliminary and periodic inspections of electrical installations, providing assurance for the long-term safe operation of equipment.
Quality assurance.
---Part 7.Requirements for Special Installations or Locations. Includes 7-701, 7-702, 7-703, 7-704, 7-705, 7-706, and 7-710.

It specifies safety protection, equipment selection, and installation requirements. The sub-sections in Part 7 are relatively independent and do not have direct connections.
connect.
---Part 8.Functional Aspects, outlining functional requirements for electrical installations. This includes sub-part 8-1, which proposes improvements for electrical installations.
Energy efficiency requirements. This document, for the first time, sets forth requirements for production and consumption-type low-voltage electrical installations in subsection 8-82.
Parts 1, 4, 5, 6, and 8 above are general sections, and most of the requirements apply to them.
Part 7.However, in special installations and locations, Part 7 provides for supplementary, modified, or superseding provisions and requirements of the general parts.
Previously, the management perspective of the public power transmission and distribution network was. centralized power generation adapted to changing demand, top-down energy flow, power supply companies, and
Achieving a balance between production and consumption among relatively passive users.
The following key factors drive changes in the power distribution network.
The increasing use of electronic devices, and potential future demands (such as charging electric vehicles), will lead to higher electricity consumption.
Structural growth;
---The pressure of climate change calls for a reduction in carbon dioxide emissions;
---The increase in electricity generation using renewable energy sources is prompting rapid changes in the electricity market (both globally and locally);
---User expectations are constantly evolving because people have increasingly higher requirements for the reliability and power quality of distribution networks, and seek...
Better economic performance and a willingness to proactively manage energy;
---Due to the low cost of information and communication technologies (ICT), new energy storage solutions are emerging, thus requiring consideration of technological advancements.
The development of technology.
All stakeholders directly involved in power generation, transmission, distribution, and consumption have new expectations.
---Users are willing to reduce electricity costs to meet environmental goals (renewable energy, energy efficiency) and also hope to benefit from improved power quality;
---Electricities hope to limit customer churn through pricing and service management;
---Producers expect to maximize their return on assets, optimize their investments, and profit from energy trading;
---Transmission system operators (TSOs) want to build a robust transmission network that meets regulatory objectives (price and service levels);
Distribution system operators (DSOs) aim to meet regulatory objectives (price and service levels) by improving productivity (including metering).
Reduce costs and have a flexible power distribution network;
Finally, governments and regulatory agencies are willing to create a competitive and sustainable energy market.
The purpose of this document is to ensure that low-voltage electrical installations are compatible with current and future operating modes, regardless of whether the electrical energy comes from a DSO or local generation.
Electricity can be safely and successfully delivered to electrical appliances. This document is not intended to influence how all stakeholders in the electricity supply sell their electricity.
And deliver electrical energy.

82.1 Scope
The requirements and recommendations set forth in this part of IEC 60364 apply to low-voltage electrical installations, whether connected to or not connected to a distribution network, and capable of operating in.
---Use local power, and/or
---Use local power storage units.
Furthermore, it monitors and controls the connected local power supply and delivers electrical energy to.
---Electrical equipment, and/or;
---Local energy storage units, and/or;
---Distribution network.
This type of electrical device is called a producer-dissipator electrical device (PEI).
All requirements and recommendations in this document apply to both new installations and retrofits of existing installations.
This document also sets forth requirements and recommendations for safety, efficiency, and normal operation when PEI is integrated into the smart grid.
Note. IEC 60364-5-56 specifies the requirements for the power supply of safety facilities.
Appendix B provides relevant information that needs to be interacted with the power grid to ensure the stability of the PEI electrical system during grid connection.
This document covers the stability requirements for both islandable and standalone PEIs.
