Design and Implementation of an Experimental Model for the Control and Telemonitoring of a 27.5kV High Voltage Bipolar Circuit Breaker with Vacuum Switching

The paper presents the design, components and Implementation of the laboratory model created for the control and telemonitoring of a 27.5kV high voltage bipolar circuit breaker with vacuum switching. This proposed experimental model was used to test a remote control and telemonitoring system in laboratory conditions for an outdoor high-voltage bipolar circuit breaker (Un=27.5kV, In=1250A, Ik= 25kA). This monitoring and control system is designated for traction substations used in the railway system and is used to power 25 kV electric lines. The remote control and telemonitoring system of the high voltage circuit breaker is a component of the experimental-demonstrative project 696PED/2022, started by the authors of this paper last year.
