Physical Security: Resiliency Against Long-Term Outages

To help utilities reach their substation security and resiliency goals, operation managers are deploying smarter physical defenses that work hand-in-hand with a reliable and secure communication network to shore up substation defenses, decrease reaction times and improve the speed of restoration. While absolute physical security is not practically achievable, it is possible to lessen the damage. ABB Power Grids has recommend a layered approach to security.
