Switch Parameters

Symbol	Description	Unit

Symbol	Description	Unit
From Bus	The phase name of the first bus	a unique name
To Bus	The phase name of the second bus	a unique name
ID	Switch name (ID)	a unique name
Status	Connect/Disconnect status	1 for close and 0 for open

Note: When the switch is on (closed) the series resistance between the From Bus and To Bus is 1e-6 p.u.

When the switch is off (open) the series resistance between the From and the To Bus is 1e6 p.u. The shunt admittance connected to the switch is G=1e-6 p.u.
