Title: Innovations of Tatsumi Ichioka

Introduction

Tatsumi Ichioka is a notable inventor based in Kounan, Japan. He is recognized for his contributions to electrical engineering, particularly in the field of line arresters. His innovative designs have significantly impacted the safety and efficiency of electrical systems.

Latest Patents

Ichioka holds a patent for an improved line arrester that features a non-linear resistor. This design includes a pair of arcing horns positioned on both the earth side and the line side of the arrester, with an aerial discharge gap situated between them. The aerial discharge gap is electrically parallel with the resistor. The length of this gap is carefully selected to prevent flashover for currents smaller than the rated discharge current of the resistor. However, it allows flashover for currents greater than the rated discharge current but lower than the critical discharge current of the resistor. This innovative arrangement protects the resistor from lightning surge currents that exceed the critical discharge current.
