    Abstract: An electrical power cable is provided with two ends and an elongated length therebetween. The cable includes one or more conductors for conducting electrical power from a power source to an electrical load. One end includes a switch and a relay to provide electrical power to the electrical load and to disconnect an electrical contact from the power conductor.

    Abstract: A wind turbine is disclosed having a generator and rectifier and structured to provide direct current power that in one form is medium voltage direct current (MVDC). The wind turbine includes a crowbar circuit arranged to protect from a condition such as an overvoltage. The crowbar can be activated based on a voltage measurement or rate of change of voltage. A resistor can be coupled to the crowbar to absorb excess power provided by the generator during the overvoltage condition. Individual wind turbines in a wind farm can each have individual crow bars that can be activated based on local measurement of a voltage condition. In some forms the crowbar can be coupled with a transformer, for example coupled with a tertiary winding of a three winding transformer.
