Abstract :
ELECTROSTATIC SHIELDING has long been recognized as an effective means of controlling the impulse voltage distribution in transformer windings. Under certain conditions the same, or a better, result can be achieved by the use of Thyrite.∗ Developed as a material for lightning arresters, Thyrite is characterized by its nonlinear resistance; it passes a current proportional to a relatively high exponent of the applied voltage. Thyrite is a ceramic-bonded inorganic resistance material manufactured in the form of disks.
