T/CPSS 1006-2021 Low-voltage parallel switching type voltage sag treatment device technical specification

Scope

Scope: This document applies to parallel switching voltage sags management devices used in single-phase and three-phase AC low-voltage distribution systems with a nominal voltage of 1,000 V or less and a nominal frequency of 50 Hz or 60 Hz. When the device detects a power supply sags event, it quickly disconnects the electrical connection between the load and the power supply. The energy storage components and bidirectional converters provide short-term power supply to the load. After the sags are eliminated, the device can switch back to the low-voltage distribution power supply. Other voltage sags management devices with similar functions can also refer to this document for implementation. Main technical content: This document specifies the related terms and definitions, system composition, and model naming rules of low-voltage parallel switching voltage sags management devices, as well as their usage conditions, technical requirements, testing, packaging, marking, transportation, and storage.
