Electrical Protection Laboratory
The laboratory is designed for measuring and testing electrical protection devices and equipment used to implement protection in the power system. The main function of the laboratory is to support the educational process of students. The laboratory also serves the needs of applied research.
Subjects and learning outcomes:
Two subjects are taught in the electrical protection laboratory: Electrical Protection in Power Systems and Protection Systems in Power Systems.
The subject Electrical Protection in Power Systems is a compulsory subject that must be completed by all students of the electrical power engineering program in the third year of their bachelor's degree. By completing the course, students will gain knowledge of the principles of operation of various types of protection, from electromechanical to modern digital protection, as well as methods of protecting electrical lines and electrical machines.
The course Protection Systems in Power Systems provides students with basic knowledge of methods for designing protection systems for individual elements of power systems, as well as for complete systems, such as protection systems for power plant units, electrical substations, and electrical transmission and distribution networks. The following activities are carried out in the laboratory:
Testing of auxiliary electrical protection devices
The laboratory has various types of instrument transformers for current and voltage, as well as current and voltage sensors, on which students verify their correct operation. Incorrect selection or operation of PNP and PTN for individual applications will significantly affect the operation of electrical protection. Therefore, verification and knowledge of the operating principles of individual instrument transformers is a very important aspect of ES protection.
Testing of digital protection devices
The laboratory provides the possibility of secondary testing of digital protection devices using Omicron CMC 156, COMPANO 100, and SEL 4000 devices. Testing of digital protection devices consists of a computational part, where students use their theoretical knowledge to numerically determine the individual parameters necessary for the correct setting of protection devices. They then enter this data manually or using ACSELERATOR QUICKSET software into the specific protection device and test the protection using Omicron Test Universe software and Omicron CMC 156 or SEL 4000 equipment.
The laboratory is equipped with a wide range of digital protections as well as real HV switchgear with integrated protection, disconnectors, and circuit breakers.
