PROTASIS Substation Automation System (SAS)

PROTASIS® Substation Automation System (SAS) is a comprehensive solution designed for the protection, control and monitoring of primary substation equipment. Delivered fully assembled and configured, the system integrates critical substation functions into a unified environment, enabling reliable and efficient operation across the entire substation.

Through real-time monitoring and control, PROTASIS® SAS enhances operational visibility and supports the reliable performance of power transmission and distribution networks. Advanced protection and automation functions enable the rapid detection and isolation of faults, helping minimize equipment damage and reduce outage duration.

By automating routine operations and reducing the need for manual intervention, the system contributes to greater operational efficiency and enhanced personnel safety. Integrated data acquisition and communication capabilities provide operators with accurate and reliable operational data, supporting informed decision-making and effective substation management.

Real-time monitoring and control of substation equipment such as circuit breakers, disconnectors, earthing switches, power transformers, on load tap changers (OLTC), and other auxiliary systems, such as AC and/or DC power supply systems.

Collection and analysis of data from various devices within the substation to ensure optimal performance and quick fault detection.

Implementation of protection & control interlocking schemes to isolate faulty sections of the network and prevent potentially hazardous operations, thereby minimizing equipment damage and increasing personnel safety.

Facilitates communication between different devices within the substation and with central control centers, often using protocols like IEC 61850, IEC-60870-5-101 & 104.

Integration of SAS with the substation SCADA system allowing operators to manage substations through a user-friendly interface.
