1. An apparatus for detecting an anomalous event and capturing an associated waveform, comprising:

  • a detection module within the power control device that detects an abnormal condition indicating;

    one or more of an impending failure of the power control device; and

    a condition within the power control device indicating that a parameter is outside a specified limit, wherein the power control device controls power to one or more power devices in a power distribution system; and

    a signal transmission module that transmits a capture signal to a plurality of transient capture instruments that measure the power distribution system at a plurality of locations in response to detecting the abnormal condition, the transient capture instruments measuring transient conditions of different legs of the power distribution system, wherein the capture signal instructs the transient capture instruments to capture one or more of current and voltage waveforms that are related to time when the abnormal condition was detected by the detection module,wherein the captured signal includes a time when the detection module detects the abnormal condition and the time in the captured signal is adjusted for any time delay before the detection module detects the abnormal condition.
