Abstract

A high-voltage coaxial-type high-pass filter is reconstructed and used to detect different impulse forms in generator bars. The test results of an old generator bar shows simultaneous occurrence of different discharge impulse forms. In this paper, the error of the band-pass filter used for PD measurement in delaminated aged bars is presented. It is essential to measure both discharge magnitude and discharge pulse forms to minimize the error.
