1. Apparatus for detecting hot spots in a power conductor in an electric power system, the apparatus comprising:

  • an electrically insulative support member having a contact surface for engaging the power conductor and a cavity in the contact surface;

    an electrically insulative thermally conductive material in the cavity extending to the contact surface to bring the electrically insulative thermally conductive material into surface-to-surface contact with the power conductor; and

    a temperature probe embedded in the electrically insulative thermally conductive material spaced from the power conductor sufficiently to be electrically isolated from the power conductor, the electrically insulative thermally conductive material having sufficient thermal conductivity to heat the temperature probe sufficiently to substantiate trends in temperature change in the power conductor.
