Under high temperature conditions, the tangent value of the loss angle of the bushing core material remains between 0.004 and 0.022
Under high temperature conditions, the real part value of dielectric constant remains between 3.9 and 4.5
Amplitude of the 50 Hz fundamental current varies between -6000 A and 6000 A
