Switching of Extra-High-Voltage Circuits IV-Compound Circuit Test Facility for High-Voltage Circuit Breakers

IEEE Transactions on Power Apparatus and Systems, 1964
A compound circuit is described for development and acceptance testing of circuit-breaker modules and circuit breakers up to 50,000 equivalent 3-phase module mva (megavoltamperes). The paper discusses high-current-source voltage requirements, synchronization of high-voltage-source application with final current zero, and high-voltage-source impedance ...

Insulative condition monitoring of high voltage circuit breaker

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
In order to improve power system reliability, high voltage circuit breaker(HVCB) as an important power equipment, the insulation state must be monitored reliably. In the paper, a design approach for real-time data acquisition and remote transmission system base on field programmable gate arrays(FPGA) and ARM technology is presented. The approach adopts

Chromatic Assessment of High-Voltage Circuit Breaker Gases

2020
Switching electric currents in high-voltage circuits involves mechanically separating two contacts to form an electric arc plasma which is then quenched. This operation is conducted in a tank containing a vacuum or one type of gas which has good arc-quenching properties.
