  "textContent": "A fault on the generator (12) can be detected with the use of a simple arrangement. The output of the generator (12) which has multi-phase winding and is driven by an engine (11) is rectified and then converted by an inverter (133) into an alternating current at the frequency of a system before interconnected to the source of the system (14). After the engine (11) is started, the direct current voltage Vdc is monitored with a first fault monitor (40). When the direct current voltage Vdc rises up to a predetermined level, a connector relay (135) is closed. As the output of the inverter (133) is increased, the interconnection with the system source (14) is enabled. After the interconnection, the direct current voltage and the output of the inverter (133) are monitored with a second fault monitor (43). If the direct current voltage drops down to below the predetermined level before the output of the inverter (133) reaches a rated level, the canceling and re-interconnection is repeated. Then, when the direct current voltage remains below the predetermined level after the re-interconnection, it is judged that the generator (12) has a fault such as a line breakage in the windings disconnection.",
