Inteligentní jistící prvky pro elektrické instalace v ostrovních sítích

Abstract

This thesis is focused on the design of the measuring station for settings and diagnosings the intelligent protection elements of the off-grid power systems. The complementary use of this station is to verify the parameters of the electromechanical circuit breaker. The thesis describes the problem of protection in off-grid power system, and later I solved the protection used in these systems. Furthermore, I designed a semi-automated measuring station including own production. Finally, I have measured and evaluated the properties and use of circuit breakers and two digital over current protections in small off-grid systems.
