minimal training requirements.
Cyber-Security
The sophistication of protection schemes, coupled with the advancement of technology,
increasingly leads to devices and substations being interconnected with open networks,
such as the internet or corporate-wide networks. This introduces a potential security risk
making the grid vulnerable to cyber-attack, which could in turn lead to electrical outage.
To secure communication within such environments, MiCOM P14N, P14D and P94V offer
NERC-compliant cyber security.
