Scope

GB/T 41135.1-2021 is the English-translated version of 故障路径指示用电流和电压传感器或探测器第1部分：通用原理和要求.

GB/T 41135.1-2021 is the Chinese standard "Current and voltage sensors or detectors, to be used for fault passage indication purposes - Part 1: General principles and requirements".

Its scope clause reads: This document specifies the minimum requirements (i.e. minimum performance indicators) for fault path indicators and power distribution units and the corresponding classification and tests (power except performance test and communication test).

This document applies to fault path indicators (FPIs) and power distribution units (DSUs) (including current and/or voltage sensing of FPIs, DSUs) device). FPI and DSU are a single device or a combination of multiple devices/functions that can be used to detect faults and indicate the location of the fault.

Considering the characteristics and operating conditions of the power system with the FPI/DSU installed, the fault location can be. --- Derived directly from the FPI/DSU; or ---From a centralized system that uses more FPI or DSU information.

Note 2.This document specifies the FPI/DSU classification according to the first "core" classification principle defined in GB/T 41135.2.taking into account the broadest Structure and fault types of distributed power distribution systems, GB/T 41135.2 describes in detail the electrical phenomena and power system responses in faults. therefore, GB/T 41135.2 is mainly to help users how to choose FPI and DSU correctly, while this document mainly focuses on the general principles of FPI and DSU and requirements.

1 Scope

This document specifies the minimum requirements (i.e. minimum performance indicators) for fault path indicators and power distribution units and the corresponding classification and tests (power except performance test and communication test).

Note 1.Fault location refers to the location relative to the FPI/DSU installation point in the grid (upstream or downstream of the FPI/DSU location) or the fault current through the FPI/DSU Orientation of DSU. Considering the characteristics and operating conditions of the power system with the FPI/DSU installed, the fault location can be.

--- Derived directly from the FPI/DSU; or

---From a centralized system that uses more FPI or DSU information.

Note 2.This document specifies the FPI/DSU classification according to the first "core" classification principle defined in GB/T 41135.2.taking into account the broadest

Structure and fault types of distributed power distribution systems, GB/T 41135.2 describes in detail the electrical phenomena and power system responses in faults. therefore,

GB/T 41135.2 is mainly to help users how to choose FPI and DSU correctly, while this document mainly focuses on the general principles of FPI and DSU and requirements.
