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 ...

Partial Discharge Measurement

2014
This chapter is devoted to the measurement of partial discharges (PD) localized in weak spots of dielectrics if subjected to high test voltages. As standards for PD measurement s have been introduced only for quality assurance tests of HV apparatus energized by power frequency AC voltages (50/60 Hz), the following treatment refers mainly to this test ...

Measuring partial discharges under pulsed voltage conditions

IEEE Transactions on Dielectrics and Electrical Insulation, 2008
Partial Discharges (PDs) measurement deserves a specific study when in the presence of fast rising/falling voltages, as the output of IGBT switching devices. In such operating conditions, the choice of a proper detection system is crucial in order to have the best signal to noise ratio and to solve some problems linked to the specific characteristics ...

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 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.

On line measurement of partial discharges

2000 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.00CH37132), 2002
On line measurement of partial discharges of equipment while in service has a great deal of potential in saving equipment down time in gas insulated substations (GIS) and gas insulated transmission lines (GITL). To address this aspect of partial discharge measurement there is scope for considerable progress particularly in the area of cables already is

LEMKE: Partial Discharge Measurements

2017
The LEMKE Partial Discharge Measurements dataset includes ASCII file outputs from PD testing of low density polyethylene (LDPE) and polypropylene film samples using a LEMKE LDS-6 measurement system. Files include PD magnitude, phase, and period number (please note voltage measurements are not valid, the correct applied RMS voltage is in the file name).

Cable model for partial discharge measurements

2016 IEEE International Conference on Dielectrics (ICD), 2016
A transient analysis software for high voltage cables has been developed as an aid to partial discharge measurements carried out to assess the insulation condition of installed cables. Knowledge of the transient behavior of cable systems allow to know if a specific measuring PD system is sensitive enough to detect partial discharge pulses that can ...

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 ...
