Innovative Solutions for Partial Discharge Measurements

Elektrichestvo, 2021
The article discusses systems developed using an innovative approach to measuring partial discharges, their advantages over traditional methods of monitoring cable lines and electrical equipment, as well as the principles of their operation. The design of the systems is based on a special broadband sensor-antenna which provides remote recording of both

Measuring system for partial discharge

Quality Measurement: The Indispensable Bridge between Theory and Reality (No Measurements? No Science! Joint Conference - 1996: IEEE Instrumentation and Measurement Technology Conference and IMEKO Technical Committee 7. Conference Proceedings, 2002
Measuring of the partial discharge (PD) parameters of the insulating systems is very important. The prompt insulating system estimation and its remaining life time give the great savings. The new, complex PD measuring methods are now developed in the world because conventional methods do not give valid information of the insulating system conditions ...

Advances in Measuring Partial Discharge in Insulating Liquids

2019 IEEE 20th International Conference on Dielectric Liquids (ICDL), 2019
The IEC 61294 Technical Report, published in 1993, describes a simple test procedure to measure the PD Inception Voltage (PDIV) in insulating liquids and doesn’t cover any other items related to the PD patterns and their evolution at higher voltages. This simplified approach should be considered superseded when taking into account the several studies ...

Partial Discharge Measurement and Analysis

2013
Partial Discharge (PD) is a common local defect of high voltage equipment, especially insulation system of transformers. PD in the insulation of electrical equipment is a sign of dielectric defects as well as a cause of further degradation of its insulation system, which may ultimately lead to failure of the apparatus.

Measurements of the energy of partial discharges

Proceedings., Second International Conference on Properties and Applications of Dielectric Materials, 2003
The purpose and the principle of measurements of partial-discharge (PD) energy are described. Two methods of PD energy measurements are presented. The first method gives the discrete values of the energy of PD pulses while the second method realized the averaging of the energy in a specific measurement time.

Amplitude Analysis in Partial Discharge Measurement

2009 Second International Conference on Advances in Circuits, Electronics and Micro-electronics, 2009
In commercial sphere, there is obvious the pursuit of produce electrical wares with high reliability and low risk of breakdown. It is known, the Partial Discharge (PD) is regarded as a parasitic effect occurring in insulating systems. Deep investigation of Partial Discharge activity is necessary for longer service life and better reliability of high ...

Partial discharge measurement and interpretation

IEEE Electrical Insulation Magazine, 1988
An overview is given of partial discharge patterns, their evaluation, and determination of their origin. Some brief comparisons of test equipment considered to be of general interest are made. The intent is to assist practitioners in the interpretation of results as well as in the accurate discrimination between true partial discharges within an ...

Partial discharges and their measurement

2004
The study of partial discharges is not an academic pursuit. It is driven by a very practical desire, a desire to understand a phenomenon which can be utilised to infer the level of integrity within the insulation systems of high voltage plant and which, in itself, constitutes a serious stress degradation mechanism. The role of partial discharge studies

A contribution on the traceability of partial discharge measurements

IEEE Transactions on Electrical Insulation, 1992
Commercially used partial discharge (PD) detectors are intended to capture current pulses generated by PD activity in the insulation of a HV test object and then to integrate it, producing a display proportional to the apparent charge. The integration procedure is approximated by a low pass (or bandpass) filter and therefore different partial detectors

Nature of partial discharges and their measurement

Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1987, 1987
There are perhaps very few measurement techniques that have contributed as much as partial discharge detection in the evaluation of high voltage apparatus, devices and cables. Notwithstanding, the progress that has been achieved over the past several decades in the description and understanding of the various mechanisms that may precipitate electrical ...
