Analysis of Measuring Methods of Grounding Insulation Resistance and Distributed Capacitance of Underground Low-voltage Power Grid

In order to verify accuracy of values of grounding insulation resistance and distributed capacitance of underground low-voltage power grid measured by AC voltammetry and AC-DC voltammetry, the Pumps Water paper introduced theory analysis and deduction of calculating formula of the two methods, and made comparison for Wovens measuring results of the

Poly-para-xylylene enhanced Fe-based amorphous powder cores with improved soft magnetic properties via chemical vapor deposition

In this work, dense and pinhole-free poly-para-xylylene (PPX) with high thermal stability, high insulating property and high lubricity has been designed as coating layer for Fe-based amorphous powder.Three ultra-thin PPX layers have been Fitted successfully deposited on the surface of FeSiBPNbCr amorphous powder via chemical vapor deposition (CVD)
