The GB/T 22689-2008 standard recommends a test method for measuring the relative resistance of solid insulating materials to surface discharge breakdown. The standard details the test equipment, sample preparation process, and operation steps for simulating surface discharge, covering key points such as voltage application methods and discharge monitoring. Through these methods, the performance of solid insulating materials against surface discharge breakdown can be evaluated under different working conditions. It provides an important basis for relevant manufacturers to control product mass and scientific research institutions to carry out research. It helps to improve the safety and Reliability of insulating materials in electrical equipment and reduce the risk of equipment failure due to insulation failure.
