[0002] In modern power systems, in order to ensure the reliability and safety of power supply, regular testing and inspection of high-voltage power equipment is essential. Especially for gas-insulated switchgear (GIS) and gas-insulated transmission line (GIL), due to their key role in high-voltage transmission and distribution systems, it is particularly important to use test fixtures to test their performance and diagnose faults.

[0003] However, traditional GIS and GIL test tools usually have the following limitations: 1. The design is not compact enough and difficult to deploy in a small or restricted field environment; 2. The connection interfaces are mostly separate designs, requiring field technicians to perform tedious wiring work, which not only increases the time for test preparation, but also increases the risk of operational errors; 3. Data collection and analysis during the test mainly rely on manual operation, which limits the accuracy and efficiency of the test.

[0004] With the development of technology and the increasing requirements for power system reliability, traditional test tools have been unable to meet the requirements of fast, efficient and accurate testing.
