The Fiske-Mott High Resistance


The principle of this insulator will become apparent to any electrician at a glance, and his first feeling will probably be one of surprise that he had not thought of it himself. Like most inventions that find their way instantly into use, it is extremely simple, and fulfils exactly the purpose for which it is intended.

In order to see clearly the reasons for the efficiency of this device, let us first review the conditions to be satisfied in an efficient insulator, and also the causes that operate to promote leakage.

In the first place, an insulator must be of very poor conducting material. The Chicago Insulator Company meet this requirement b
