If interlocking test with protection panel is required CBS (Circuit Breaker Simulator)
CBS ( Simulated test device for breakers if interlocking test with protection panel is required )
Summary
Introducing CBS: CBS is a circuit breaker simulator that allows for a replacement of
the field circuit breaker during the Testing of Interoperability with the protection
circuit, as well as the testing of 765kV recloser.
- Circuit breaker simulator that can execute transmission line reclosing system without a
direct motion of the actual circuit breaker - A simulator that makes possible the performance of an automatic test analysis at the same
time as the test by interlocking an analysis system that confirms the analysis and results of
the motion before and after the Testing of Interlocking
Technology application transferred from KEPCO(Korea Electric Power Corporation) Diagnosis Center
(Skills transfer performance) / Completion of site field test KEPCO Equipment Diagnosis Center /
Completion of verification of KEPCO Research Institute Protected Relay Demonstration Center

Necessity
In advanced countries, the number of breaker operations (100 to 200 times for UAE nuclear power) is severely limited due to
increased possibility of accidents caused by excessive number of blockers such as iron particles due to tests and other tests,
whereas in Korea, the number of blocks is overworking without any limit on the number of operations.
Substation Field Situations
- Direct operation of the real circuit breaker during the Testing of Interlocking for transmission line reclosing system
- Direct operation of the actual circuit breaker during the Testing of Interlocking of the other protection systems
Problems
- Because the circuit breaker is repeatedly being operated in order to verify the reclosing system and protective relaying Testing of Interlocking,
not a circuit breaker self-test, unnecessary motion operations are brought about in view of the circuit breaker - Because the circuit breaker is over-operated during the test, it may exert influence on the maintenance and life cycle of the circuit breaker,
thereby leaving the possibility of a breakdown - There is a necessity for verification of reliability by arbitrarily altering the Trip and Close times of the circuit breaker. however, the actual
circuit breaker is controlled, so an effective verification is impossible
Special Features
- Unconstrained setting function of Trip Time, Close Time
- Interlocking function between test sets that can simultaneously test the upper part and socket of the circuit breaker
- Provision of simultaneous operation of test equipment and analysis system, and independent operation of test equipment
- Circuit breaker simulator that operates the function of a circuit breaker that supports 154kV, 345kV, 765kV, including Digital Input and
Digital Output - Simultaneous test analysis performance with the implementation of analysis system, that allows for analysis and results of signal function
before and after the circuit breaker simulator

Software Functions
- Recording of operation results with a Comtrade format
- Delay setting and instrument indication concerning the Trip and Close of circuit breaker
- Reception and analysis of Binary Input signal and Binary Output signal
- Signal movement analysis and analysis result confirmation before and after the circuit breaker simulation test provided through I/O module
Expected Results
- Prevention of malfunctioning and shortening of service life due to the extremely reduced number of operations of the actual circuit breaker
- Reduction of adverse effects and cost reductions of circuit breaker maintenance
- Possibility of verification through minimization of opening and closing of the actual field circuit breaker during the conclusive test of reclosing transmission line protection
- Real-time test results are available, which shortens the period of analysis of failure causes of Testing of Interlocking, through which it enables accurate verification of protection system
- Shortening of unnecessary waiting time due to the decrease of hydraulic pressure or air pressure of the circuit breaker during test
- Possibility of self-verifying the reclosing system without operating the circuit breaker, which reduces the time required for testing by 1/10 or more
