High Voltage Terminations - Videos and Related Books
Summary
This 55-minute video covers basic theory and typical practices for terminating conductors in substations and switchyards. It explains the importance of minimizing voltage stress and of maintaining proper clearances in high-voltage terminations. Examples of commonly used connection hardware are shown, and their uses are explained. Examples of typical high-voltage terminations are given to illustrate the basic principles.
