    摘要： A surge protection system provides surge protection to one or more circuits. Each circuit is connected to power and a surge protection module bridges the circuit such that the surge protection module absorbs surges from the power and/or the circuit. Being that, after exposure to certain amounts of surges, the surge protection modules lose effectiveness for surge protection, each surge protection module is independently removable and replaceable by a user without risk of personal injury from shock caused by making personal contact with the power and/or circuit. In some embodiments, a filter circuit is provided to filter out noise on the circuit. It is anticipated that the protection module includes indicators to inform a user that the protection circuit is operational and whether protection has been lost. Further, in some embodiments, a fuse is provided to protect the circuit from over current.

    摘要： Apparatus to provide arc flash protection regarding a wind turbine. In one embodiment, a wind turbine (10) includes a wind turbine generator (12) to generate an alternating current power. A transformer (14) has a high-voltage side (16) coupled to a load. A circuit breaker (18) is adapted to selectively reduce arc flash energy available to the wind turbine. The circuit breaker may be arranged to provide circuit interruption between the generator and a low-voltage side (20) of the transformer upon detection of a fault condition. The circuit breaker includes an arc flash protection mode (24) and a normal protection mode (22). In response to a sensed condition, a respective one of the modes may be automatically set so that the circuit breaker can perform the circuit interruption in accordance with the protection functionality of the set mode.
