摘要：

A newly developed colloidal magnetic fluid (MF) has been investigated for use as high-voltage insulation. Being a liquid magnet, MF interacts with the magnetic field of transformer windings and improves their cooling, while at the same time MF increases the lightning impulse withstand voltage and decreases the discharge propagation velocity, probably due to an enhanced electric field dissipation due to the presence of magnetite nanoparticles.
