ABSTRACT:
A method is provided for utilizing a nonintrusive, noncontacting electric field sensing device to detect faults in high voltage transmission line insulators. The electric field surrounding an unfaulted insulator is mapped using a spherical dipole to obtain a characteristic reference curve. The field of a suspect insulator is then mapped to obtain a test curve which is compared with the reference curve to determine the existence of and location of a fault.
