Our team, with their expertise in architecture, R&amp;D,\u00a0schematics, BOM and DSP, delivered a solution that met the client&#8217;s\u00a0requirements. The relay was designed for earth faults, short circuiting,\u00a0over voltage and overload protection. It collects real-time data from CTs\u00a0and PTs and acts instantaneously to mitigate the fault by sending a cutoff\u00a0signal to CBs (Inverse Definite Minimum Time and Definite Minimum Time\u00a0techniques implemented in firmware). The relay communicates to other\u00a0devices through RS-485 MOD-Bus RTU. It has a number of boards\u00a0including a Binary Input and MOD Bus(Power Supply), CT Board, Relay\u00a0Board, and Relay Controller Board. The system architecture design was\u00a0carried out in accordance with the user requirement document. The relay\u00a0was designed for harsh and critical interference environment and was\u00a0tested for its performance. The firmware was developed for ARM4, with\u00a0internal ADC sampling at 20ksps, FIR LP and HP filter design and half\u00a0duplex RS485 MOD Bus RTU. The communication interfaces used were\u00a012C, R523, RS485, SAI, and SPI. The project was completed in June 2018\u00a0to July 2020 and was delivered on time and within budget.<\/p>\n<p>https:\/\/etazsys.com\/wp-content\/uploads\/2023\/11\/etaz-system-website-Feeder-Protection.mp4#t=21<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Project 3 Feeder Protection Relay for HV Feeders Introduction: \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0etaz Systems was approached by a client to design a Feeder Protection\u00a0Relay for HV Feeders.
