Experimental investigations of void dynamics in a dusty discharge

A Novel Approach to Partial Discharge Monitoring

On-line partial discharge (PD) monitoring has existed in some form since the early 1980s. It is the tool of choice to evaluate the health of the stator insulation on large rotating machines. However, analysis of partial discharge results remains difficult to most users and advanced interpretation is usually reserved for experts in the field. While the hardware development has matured, it hasn’t...

A New Partial Discharge Measuring System Calibrator

A new PD (partial discharge) measuring system calibrator is described. The device, battery operated, may be used either grounded or in a floating position, and generates securely mains-synchronized impulses by capacitive coupling. It allows the determination of the scale factor k and resolution time Tr in PD measuring systems, and it fulfils the requirements of International Standard IEC 60270....

Partial Discharge Detection in Solid Dielectrics

Partial Discharge (PD) measurement and characterization provide vital information on insulation condition, different aspects of insulation ageing useful for equipment integrity verification and diagnosis. The work demonstrates standard test methods which employs capture of PD parameters with the aid of discharge detector. This paper investigates on the voltage amplitude at which PD of a specifi...
