RELAY PROTECTION TESTER MODEL NO.JBC 703 4U 3I

Optical Differential Relay Protection Model

Optical Differential Relay Protection Model

As OCT has no magnetic saturation, no band limits, and can accurately and quickly transform the full-waveform current signal in principle, the authors put forward a new optical differential protection algorithm which directly use the integral values of the operating current and the. Apply the SEL-411L for complete protection and control of any transmission line (short, long, or series-compensated). With its flexibility and the high-performance DIGSI 5 engineering tool, the SIPROTEC 7SD82 device offers future-oriented. This project work focuses on the design of one such system comprising of microcontroller based line differential protection using fiber optics communication.
