This article is planned to be a guideline for secondary protection practices basic calculations and setting procedures for DEMA MCR 310 Electronic Overcurrent Protection Relay. To form a basis for the calculations, a sample project /with the single line diagram on the left is created. When evaluating the project, it must be noted that;
- The project and single line diagram are completely fiction,
- The component ratings are given as sample values and may not necessarily represent any component ratings in the market,
- The component selections are not based on engineering fundamentals and thus must not be translated as selection suggestions or templates.
The following pdf contains calculations, estimations, and graphics that show the fundamentals of protection for a power transformer by using the DEMA MCR 310 Electronic Overcurrent Protection Relay.
