SWITCHING SURGE PROGRAM · Tools

This program was originally written in Fortran in 1989 by David R. Brown and the American Public Power Association.

The following sources provided data on the electrical properties of different conductors:

IF SHIELDS ARE SEGMENTED (INSULATED) TO PREVENT 60 HZ SHIELD WIRE CURRENTS, SHIELD WIRE CURRENTS SHOULD BE SET TO ZERO.

LINE LENGTH IN MILES

THE SWITCHING SURGE PROGRAM SIMULATES LINE RECLOSING ASSUMING TRAPPED CHARGE ON THE LINE. THE SYSTEM TO WHICH THE LINE WILL BE CONNECTED IS MODELLED ON THE BASIS OF THE SYSTEM THREE-PHASE FAULT CURRENT.

THREE-PHASE FAULT CURRENT FOR THE SYSTEM IN AMPERES

SIMULATION OF INSERTION RESISTORS

Omit insertion resistance and resistor insertion time if you chose to omit resistors

insertion resistance(OHMS)

resistor insertion time (ms)
