DL/T 536-2023 DL/T 536-2023 Technical Conditions for the Use of AC Coupled Capacitors and Capacitive Voltage Divider
Basic Information
Scope
This document specifies the terms and definitions, usage conditions, technical requirements, testing and marking for AC coupling capacitors and capacitor dividers. This document applies to AC single-phase coupling capacitors with a rated AC voltage of more than 1000 V, connected between the line and ground, with the low-voltage terminal permanently grounded or connected to power line carrier (PLC) accessories, harmonic filter tuning devices, and AC single-phase capacitor dividers used in the manufacture of voltage transformers, as well as other similar applications. Note 1: The requirements for carrier accessories used in power line carrier (PLC) systems refer to GB/T 19749.2, the requirements for tuning units refer to GB/T 19749.3, and the requirements for AC single-phase capacitor dividers used in the manufacture of voltage transformers refer to GB/T 19749.4. Note 2: The requirements for large-capacity frame-type AC PLC capacitors refer to GB/T 31954.
