GB/T 26216.1-2019 in English

1. Overview of the standard

GB/T 26216.1—2019 is Part 1 of "DC current measuring devices for high-voltage DC transmission systems", which mainly regulates the technical requirements for electronic DC current measuring devices. This standard is applicable to DC transmission systems with voltage levels of ±1100 kV and below.

Compared with the old version of the standard (GB/T 26216.1—2010), the new version of the standard adds applicable scenarios for flexible DC transmission systems, and expands and optimizes technical parameters such as rated current and voltage.

4. Analysis of Technological Evolution

The development of electronic DC current measuring devices is mainly reflected in the following aspects:

• The transition from analog output to digital output has improved the measurement accuracy and transmission efficiency.
• Increased the adaptability requirements for flexible DC transmission systems.
• The insulation design and test methods have been optimized to cope with the needs of higher voltage levels.

5. Implementation Suggestions

Selection and Configuration: Select appropriate measuring devices according to the characteristics of the project. For example, for high voltage level systems, devices with higher insulation levels and accuracy should be given priority.

Installation and Commissioning: Ensure the normal operation of the equipment under rated conditions, and calibrate and test in accordance with standard requirements.

Maintenance and repair: Regularly check the insulation performance and measurement accuracy of the equipment, especially the equipment operating in harsh environments needs to be monitored more closely.
