Abstract :
A new porcelain post insulator for transmission lines, which is free from radio effect at its operating voltage, is described in this paper. Capacitance measurements are utilized to determine and rate the radio characteristics. Other points of design are described, such as improved leakage path to resist arcing in contaminated atmosphere, greater height to avoid grounding by birds, and increased resistance to destruction by internal cracking, puncture, and breakage.
