GB/T 3334-1999 "Test Method for Dielectric Dissipation Factor (tan δ) of Cable Paper (Bridge Method)" specifies the test method for determining the dielectric dissipation factor (tan δ) of cable paper using the bridge method, which is applicable for assessing the insulation performance of cable paper. It clarifies the sample preparation, testing environment, bridge instrument parameters, and operational procedures. By measuring the dielectric dissipation factor, the energy loss of cable paper under electric field conditions is evaluated, ensuring the safe operation of cable insulation systems.
