Abstract
An apparatus for evaluating an electrical insulator includes: a frame having a base and a pair of spaced-apart resilient arms each having a distal end; and a flexible probe disposed between the arms, the flexible probe being generally U-shaped and having a pair of distal ends, each distal end of the probe being connected to a respective distal end of one of the arms.
Claims22
An apparatus for use in evaluating an electrical insulator, comprising:
- a frame having a base and a pair of spaced-apart resilient arms each having a distal end;
- and
- a flexible probe having a flexible metallic tensile strip embedded within an insulator cover disposed between the arms and configured to receive the electrical insulator, the flexible probe being generally U-shaped and having a pair of distal ends, each distal end of the probe being connected to a respective distal end of one of the arms.
An apparatus for identifying high risk insulators with conductive or high permittivity defects, comprising:
- an enclosure containing electronics for controlling measurement and communication processes;
- and
- first and second spaced-apart electrode assemblies for engaging an insulator to be tested, the first and second electrode assemblies being mounted to the enclosure and operably connected to the electronics;
- wherein each of the first and second electrode assemblies comprise:
- a frame having a base and a pair of spaced-apart resilient arms each having a distal end;
- and
- a flexible probe disposed between the arms and configured to receive the electrical insulator, the flexible probe being generally U-shaped and having a pair of distal ends, each distal end of the probe being connected to a respective distal end of one of the arms.
