A device for detecting proximity to an active alternating current (AC) voltage source is provided. The device includes a housing, at least one antenna configured to generate a signal in response to exposure to electromagnetic radiation, signal processing circuitry configured to process the signal generated by the at least one antenna, a microprocessor configured to determine, from the processed signal, whether the alert device is proximate to the active AC voltage source, a communication device configured to generate a signal in response to a determination that the alert device is proximate the active AC voltage source, and an interference reduction device configured to discharge an accumulated charge on the alert device to reduce electromagnetic interference from sources other than the active AC voltage source.

Mining detection system and method

A method for suspending a rotor blade uptower includes mounting a first end of a support structure at a first uptower location of the wind turbine. The method also includes securing the rotor blade to a second end of the support structure. Further, the method includes mounting at least one pulley block assembly between a second uptower location and the support structure. Moreover, the method includes routing at least one pulley cable from at least one winch over the at least one pulley block assembly. In addition, the method includes detaching the rotor blade from the hub of the wind turbine. Once the rotor blade is detached, the method includes rotating the support structure about the first end via coordinated winch operation so as to lower the rotor blade a predetermined distance away from the hub. Thus, the method also includes suspending the rotor blade at the predetermined distance away from the hub via the support structure.
