Substation Zone Of Influence
Substation Zone Of Influence
(OP)
I am looking for assistance in calculating the 300V Zone of Influence with respect to communications equipment protection at a substation. Does anyone have any references on this?

One reference is IEEE standard 367 Recommended Practice for Determining the Electric Power Station Ground Potential Rise and Induced Voltage From a Power Fault

Unfortunately, IEEE does not provide much of anything for free these days, but PDF availability does simplify things a bit.

since it addresses in:

the 300 Volts Point Zone of Influence

Significant induce voltage could be created on control and low voltage power cable by surge during switching, lightning or fault conditions in a substation.
Fiber optic could be an option for control system since is naturally immune to induce voltage.
The enclose article could be helpful for your application.

I don't have access to IEEE Std 487 or 367, but wouldn't a calculation of equipotential lines around a facility during a fault give you the 300 volt zone of influence. Several grounding packages (for instance SES CDEGS) allow modelling of the ground system and calculation of earth potential at various points.
