標(biāo)準(zhǔn)名稱

ASTM D149 Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies

ASTM D149固體電絕緣材料在商用電源頻率下介電擊穿電壓和介電強度的標(biāo)準(zhǔn)試驗方法

?

適用范圍

Scope:

This test method covers procedures for the determination of dielectric strength of solid insulating materials at commercial power frequencies, under specified conditions. Unless otherwise specified, the tests shall be made at 60 Hz. However, this test method is suitable for use at any frequency from 25 to 800 Hz. At frequencies above 800 Hz, dielectric heating is a potential problem
