Introduction

This standard covers insulating materials and systems. Voltage endurance tests are used to compare and evaluate electrical insulation materials and systems. Sure electrical The AC voltage durability of edge materials and systems is very complicated, because the voltage durability test results are affected by many factors. This standard is proposed to A unified method for simple design and analysis of voltage durability tests. Electrical insulation materials and systems AC voltage durability assessment

1 Scope

This standard describes many factors related to electrical insulation materials and system voltage durability tests, describes voltage durability curves, and lists The test method and its limitations are defined, the terminology of voltage durability is defined, and the sinusoidal intersection of the insulation material and the system is evaluated based on the test results. Guidelines for Durability of Streaming Voltage. This standard is applicable to the durability assessment of insulating materials and systems under AC voltage with a voltage frequency of 20 Hz to 1000 Hz. The test principles used in this standard are also applicable to other waveform voltages.
