GB/T 39853.1-2021 is the Chinese standard "Power quality measurement in power supply systems - Part 1: Power quality instruments(PQI)".

Its scope clause reads: This part of GB/T 39853 specifies the measurement method (Class A or Class S) defined by IEC 61000-4-30.2015, with The performance requirements of products and instruments that measure, record and monitor the power quality parameters of the power supply system.

These requirements apply to single-phase, two-phase (divided Phase) and three-phase AC 50Hz or 60Hz power supply system.

Such instruments are used for. ---In power generation, transmission and distribution systems, such as power plants, substations or distributed power generation systems; --- The connection point between the facility and the power grid, for example to check whether the power grid operator and user follow the connection agreement.

Note. These instruments can also be used in other applications, such as in commercial and/or industrial facilities, especially where comparable measurements are made (such as data centers or petrochemicals). plant).

These instruments are either fixed or portable, and are used indoors and/or outdoors. Equipment such as digital fault recorders, electric energy/power instruments, protective relays or circuit breakers can be equipped with IEC 61000-4-30.2015 Defined Class A or Class S power quality functions.

If such equipment is required to comply with this part, then in addition to the relevant product standards, this part is fully applicable. Used for these devices.

This part does not replace relevant product standards. This section does not involve user interfaces or topics that are not related to the measurement performance of the device.

This section does not cover the post-processing and interpretation of data, such as special software.
