The SIPROTEC 7SS52 distributed busbar and breaker failure protection consists of compact bay units which are connected to the central unit by fibre-optic cables. All tasks from acquisition of the measured values up to the commands to the circuit breakers are exclusively processed in a digital manner.
In the bay units the feeder or coupler currents are measured time-synchronized, digitalized, pre-processed and transmitted to the central unit.
The central unit reads in time-synchronized measured currents from the connected bay units and processes them together with binary information from the protection functions (differential protection, breaker failure protection).
The central unit transmits the results of the calculations cyclically to the bay units, which perform logical combinations of the results.
The Configuration of Siemens Siprotec-4 De-Centralized Bus Bar Protection Relay using DIGSI-4 Software will be discussed in this series of sessions. This series will consists of 7-8 sessions. At the end of this series you will learn the various aspects of Siemens Dec-Centralized Bus Bar Relay configuration using Digsi Software. We will also discuss about the meanings and implications of various settings available in central unit and bay units of De-centralized Bus Bar Protection. All the sessions will be in Hindi as well as English and you may watch these sessions as per your convenience.
An incredible amount of time and effort is needed to develop high-quality video tutorials. Each video takes approximately 6-8 hours to complete which includes learning the concept myself, brainstorming creative ways to teach and explain the concepts, creating the presentations (if delivered through PPT mode), Setup of analysis software, video recording, and editing. Your support truly makes all the difference. So, Please like👍🏻, comment and share this video with your friends and keep watching this channel for more such videos in future.
