Space charge

View this topic in
Space charge is a concept in which excess electric charge is treated as a continuum of charge distributed over a region of space (either a volume or an area) rather than distinct point-like charges. (Wikipedia.org)

The role of space charge in the theory of solid-dielectric breakdown

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1983, 1983

The first theory for low temperature electrical breakdown in solids was given by Zener[1] who calculated the field strength at which quantum mechanical tunneling from valence to conduction levels should become significantly large. This criterion for breakdown would clearly produce conditions leading to failure of insulating properties, but the critical fields calculated in this way are an order of magnitude ...

The hidden threat to HVDC polymeric insulation at design field: Solitonic conduction

IEEE Electrical Insulation Magazine, 2014

While HVDC assets are impetuously expanding worldwide, the design of HVDC polymeric insulation systems still contains unknowns. It has been ascertained that space charge plays a fundamental role in DC insulation reliability because of modifications it may induce in the (Poissonian) electric field distribution, especially when heterocharge is formed during voltage application. Heterocharge (charge close to an electrode of opposite ...

  • Modeling the Electrical Conduction Behavior of Polymers

    For the design of electrical insulation systems the knowledge of the spatial field distribution is essential in order to avoid electrical overstress. Therefore, a simulation model is required taking into account the electron emission and charge transport processes. First, this paper discusses the physical processes of charge emission, transport and trapping. At the cathode- polymer interface the relevant emission mechanisms are the field-relieved thermal Richardson-Schottky emission and the field emission by Fowler- Nordheim. The transport model is based on the continuity equation enhanced by activation processes. According to these mechanisms a physically motivated model is developed and an appropriate computation algorithm is implemented. By the use of the algorithm the time-dependent conduction behavior of polymers is simulated. Measurements of the electrical conduction behavior confirm the characteristic simulation results. Furthermore, the space charge distribution inside the insulation system is analyzed. The analysis elaborates the time dependent space charge distribution as well as the electric field and current density distribution. The major goal of the developed model and algorithm is the simulation of the electric field and space charge distribution aiming at a deeper understanding for the resulting conduction behavior of polymers in order to optimize the design process in an early stage.

  • The hidden threat to HVDC polymeric insulation at design field: Solitonic conduction

    While HVDC assets are impetuously expanding worldwide, the design of HVDC polymeric insulation systems still contains unknowns. It has been ascertained that space charge plays a fundamental role in DC insulation reliability because of modifications it may induce in the (Poissonian) electric field distribution, especially when heterocharge is formed during voltage application. Heterocharge (charge close to an electrode of opposite polarity to that of the electrode) can increase the electric field at the interface between electrode and polymer, thereby enhancing injection from the electrode. This can cause so large a field concentration as to increase the conductivity abruptly and lead to insulation failure due to the electrical discharge process called, usually, thermal instability breakdown [1], [2].
