Interfaces between dielectrics are considered one of the weakest parts of an insulation system but their behavior under electrical stress is not yet completely understood. In particular, when a dc voltage is applied, the electric field distribution at the interface is quite difficult to predict. This is mainly due to the accumulation of internal charge, which distorts the initial Laplacian field. To shed some new light on this topic, space charge measurements were performed on two types of coaxial XLPE-EPR interfaces. A numerical procedure, based on the Maxwell-Wagner theory for interfacial polarization, was developed for the estimation of the dynamic charge build-up at the interface. Experimentally obtained space charge profiles were compared to the calculated profiles. The limits of the Maxwell-Wagner model were assessed and the main parameters, which affect the interfacial polarization but which are not included in the model, were identified.

“…In most of the cases, the PEA method [8,9] was used for this goal. Hitherto, several kinds of multi-dielectrics have been tested by means of the PEA method [2][3][4][5][6][7][10][11][12][13][14], but only little attention has been paid to the fact that, generally, the PEA method does not directly provide the space charge distribution within the sample if the sample is composed of different insulation layers [15][16][17][18][19][20].…”

The Pulsed Electroacoustic (PEA) method is now widely accepted as one of the most simple and effective techniques for the measurement of the dynamic space charge distribution in solid dielectrics. Recently, the PEA method has been applied also to laminar test objects composed of two or more layers of different dielectrics (multidielectrics). However, when a multi-dielectric is tested by means of the PEA method, the different acoustic and electric properties of the materials affect the detected space charge signal. In this paper, the principle of the PEA technique is reviewed in case the test object is a multi-dielectric. The generation, transmission and reflection of electrically-induced acoustic waves are described. Based on the proposed approach, results of PEA measurements performed on various kinds of multi-dielectrics are presented and discussed.

“…To investigate space charge, both destructive and nondestructive techniques have been in use since 1970s. They include thermal pulse method (TPM) [93], thermal step method (TSM) [94], laser intensity modulation method (LIMM) [95], pressure wave propagation method (PWP) [96], laser-induced pressure pulse method (LIPP) [97] and the pulse electroacoustic method (PEA) [98]. Today, the PEA method is one of most popular measurements for evaluating dielectric materials on space charge behavior; this method can also be modified and improved for different purposes.…”

Abstract-Increased renewable energy integration and international power trades have led to the construction and development of new HVDC transmission systems. HVDC cables, in particular, play an important role in undersea power transmission and offshore renewable energy integration having lower losses and higher reliability. In this paper, the current commercial feasibility of HVDC cables and the development of different types of HVDC cables and accessories are reviewed. The non-uniform electric field distribution caused by the applied voltage, temperature dependent conductivity, and space charge accumulation is briefly discussed. Current research in HVDC cable for higher operation voltage level and larger power capacity is also reviewed with specific focus on the methodologies of space charge suppression for XLPE extruded cables.
