Abstract :
For pt.III see ibid., vol.6, no.6, p.11 et seq. (1990). Commercially available partial discharge (PD) detectors are described, along with their important characteristics. The primary characteristics that detectors have in common and that are used as a basis for classification are the number of inputs used, the bandwidth of the detector, and the method of display processing. Ancillary test components, which complete an integrated test system, are discussed. PD measurements for quality assurance require not only a detector, but an entire system coordinated to maximize the measurement sensitivity for the specific type of apparatus under test. To illustrate how a coordinated system is applied, examples of some systems in commercial use are provided.<>
