Field of the Invention The present invention relates to a pulse voltage detection circuit for a circuit breaker, which detects a tripping time, i.e. the time at which an arc starts in the closed state of a circuit breaker, to allow the timing for the tripping operation of the circuit breaker to be accurately determined. 2. Description of the Related Art An example of a conventional circuit breaker is described in Japanese Unexamined Patent Publication No. 2001-228186, for example. This circuit breaker includes a vacuum-tight switch having an external electrode and a secondary winding and is connected to a load via the secondary winding. A first signal generating circuit detects a current flowing through the external electrode. A second signal generating circuit detects a voltage induced in the secondary winding. A time calculation circuit calculates a time from the occurrence of the current detection until the voltage detection. A current detection timing detecting circuit detects a detection time, i.e. a current detection time, when the current exceeds a predetermined level. A current detection output signal is output to a current detection circuit when the current detection time is detected. A voltage detection time detecting circuit detects a voltage detection time when the voltage exceeds a predetermined level. A voltage detection output signal is output to a voltage detection circuit when the voltage detection time is detected. A tripping operation circuit generates a tripping instruction signal when a predetermined period of time has elapsed from the output of the current detection output signal and the output of the voltage detection output signal. A tripping operation circuit outputs a tripping instruction signal to a tripping circuit to open the switch when the tripping operation circuit detects that the current detection time is detected. The current detection circuit detects a current induced in the secondary winding when the switch is opened, and the tripping circuit detects a current induced in the secondary winding when the switch is closed. In the circuit breaker described in the above-mentioned document, a power system current detecting unit, i.e. the first signal generating circuit, detects the current and outputs a detection signal when the current exceeds a predetermined level. An induced voltage detecting unit, i.e. the second signal generating circuit, detects a voltage induced in the secondary winding and outputs a detection signal when the voltage exceeds a predetermined level. A current detection timing detecting unit detects a current detection timing, i.e. a current detection time, when
