ASTM D149固体电绝缘材料在商用电源频率下介电击穿电压和介电强度的标准试验方法
标准名称
ASTM D149 Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies
ASTM D149固体电绝缘材料在商用电源频率下介电击穿电压和介电强度的标准试验方法
适用范围
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
