| 摘要 |
The invention relates to a test system and a method for testing a circuit breaker (2) of an electric switchgear. A sub-station battery (3) of the electric switchgear is used to generate a supply voltage (7) for the circuit breaker (2) to test the same, wherein the sub-station battery (3) is coupled to a test device (1) in order to generate the supply voltage (7) for the circuit breaker (2) from an input voltage (6) provided by the sub-station battery (3). The supply voltage (7) is stabilized with the aid of a voltage regulator (11) of the test device (1). |
