DL/T 618-2022 in English

The standard "Code for On-site Acceptance Tests of Gas-Insulated Metal-Enclosed Switchgear" with the number DL/T 618-2022 was published on May 13, 2022. It officially came into effect on November 13, 2022. This standard sets out detailed procedures and requirements for conducting acceptance tests at the installation site of Gas Insulated Metal Enclosed Switchgear (GIS). These tests are crucial to ensure that the GIS equipment is functioning correctly and meets all necessary safety and operational standards before being put into service.

DL/T 618-2022 covers various aspects including but not limited to insulation testing, mechanical characteristics verification, electrical performance evaluation, and sealing integrity checks. It also includes guidelines for test preparation, execution methods, data recording procedures, as well as the interpretation of results and recommendations based on those findings.

The standard aims at providing a unified approach to enhance safety measures in power systems by ensuring that all equipment meets stringent quality control standards throughout its lifecycle from installation through operation. By adhering to this code, utilities and manufacturers can minimize risks associated with electrical failures, thereby contributing towards the reliable and efficient distribution of electricity.
