| Communication Gateway | Protocol bridging and data routing | IEC 61850, DNP3 | Interoperable integration |
| Human Machine Interface | Visual monitoring and control | Web, SCADA compatible | Centralized situational awareness |
| Automation Engine | Auto switching and sequence control | Sub second response | Reduced outage duration |
Core Protection Logic and Settings
Overcurrent and Differential Schemes
PSP S PS employs overcurrent, directional overcurrent, and differential protection to detect phase and ground faults. Engineers can set pickup values, time curves, and restraint levels to match network impedance and loading conditions.
Seamless Integration with SCADA
Through standardized communication protocols, PSP S PS connects to existing SCADA and control centers. Data points such as currents, voltages, and relay status are visualized, archived, and used for automated decision workflows.
Device Configuration and Engineering Workflow
Project Templates and Libraries
Prebuilt templates for feeders, transformers, and generators accelerate engineering. Reusable device libraries ensure consistent logic, naming, and parameter sets across substations and sites.
Offline Editing and Version Control
Configuration is performed in an offline engineering tool before deployment. Change tracking, baselines, and rollback features protect against unintended edits and support coordinated updates.
Deployment, Commissioning, and Testing
Hardware Installation Guidelines
Relay panels, metering sensors, and communication switches are installed following strict electrical and environmental standards. Proper grounding, wiring, and labeling reduce noise and improve measurement accuracy.
Functional and Performance Tests
Commissioning procedures include relay testing, communication checks, and synchronization validation. Test reports capture settings, measured trip times, and verification of protection coordination curves.
FAQ
How does PSP S PS achieve selective fault isolation?
By coordinating inverse time overcurrent curves, directional elements, and differential pilot schemes, the system isolates only the affected section while preserving supply to healthy feeders.
Can PSP S PS integrate with legacy protection hardware?
Yes, communication gateways support multiple protocols and legacy interfaces, enabling data exchange with older relays without full hardware replacement.
What cybersecurity measures are built into PSP S PS?
Role based access control, encrypted communication, secure boot, and firmware signing help protect relay networks against unauthorized access and tampering.
What maintenance schedule is recommended for PSP S PS devices?
Annual functional tests, quarterly communication health checks, and periodic calibration of sensors ensure sustained accuracy and reliability over the asset lifecycle.
