MEASUREMENT STAND FOR STUDY PROPERTIES OF ISOLATION MATERIALS USING POLARIZATION METHOD
Abstract
The article presents measurement stand, which is used to measure polarization and depolarization currents, using PDC method, in wet transformer oil-impregnated cellulose isolation. Maximum resolution of measured currents reaches 10-15 A. The accuracy of thermal stabilization, in three-electrode capacitor system, comes to 0,001 °C.
