Looking for a program that can do this: Allow me to draw the high voltage open ring system of a site, consisting of SF6 circuit breakers, ring main units and transformers. This will be displayed on a pc screen and enable me to change the state of circuit breakers and rmu's from open to close. This will only be what is displayed on the screen and is for simulation - no actual connection or control of field equipment. For example, a transformer is supplied from a circuit breaker, the circuit breaker is ON. The cable to the transformer would be one colour, if I switched the CB off, the cable would change colour to indicate that supply is off. The program is for simulation purposes only so that it can be used to assist in putting together switching schedules, and to aid functional switching. Can anyone suggest a program available to do this?
TIA
