NUMERICAL PANTO FLASH-OVER PROTECTION RELAY
➢ Advanced Digital Fourier Transform based Numerical algorithm design using 16-bit Digital Signal Controller (DSC).
➢ Compact Construction covering several protection modules saving panel space.
➢ Highly resilient against Voltage, Climatic, EM and Mechanical stress.
➢ Man-Machine Communication through 20×4 character LCD display and LEDs.
➢ Self supervision of both hardware and software units.
➢ Interface ability with SCADA can be achieved through IEC 60870-5-103 and IEC 61850 communication protocols.
➢ Facility for storing fault wave-forms (Disturbance recorder) and events with date and Time stamping.
➢ Front accessible communication port for Fault analyzing/Setting modification through GUI.
➢ Graphical User Interface for analysis. Harmonic analysis, DC analysis and di/dt analysis can be done on the uploaded fault wave forms with facility for report generation.
➢ Facility to access/modify the relay settings both online as well as through menu in local PC through SCADA at RCC.
➢ Relay Indication (LED) reset from RCC.
➢ Suitable password protection.
➢ GPS time Synchronization Facility through IRIG-B.
➢ Settable CT and PT ratios.
➢ CB close and open command initiation from relay through RCC.
