Understanding the Cybersecurity Risks

Transformer protection systems, integral to managing the flow and integrity of electrical power, now often rely on digital and networked technologies. These systems are targets for cyber threats due to their critical role in energy distribution. Cyberattacks can lead to the unauthorized manipulation of protective relays, resulting in false tripping, sustained outages, or physical damage to the transformers themselves.

Types of Cyber Threats

  • Targeted attacks: Specific systems are targeted to disrupt power supply operations.
  • Malware and ransomware: Software designed to damage or gain unauthorized access to the system.
  • Data breaches: Unauthorized access to system data, potentially compromising operational security.

The Expanding Threat Landscape for Transformer Protection

Traditional transformer protection schemes relied on isolated relays with minimal network connectivity. However, the integration of digital relays and communication networks for remote monitoring and control...
