Space Charge Distribution Measurement using PEA Method
-Encounter with unexpected behavior
Professor Yasuhiro Tanaka
Measurement and Electric Machine Control Laboratory,
Tokyo City University, Japan
Synopsis:
Space charge accumulation phenomenon is one of key factor to resolve a problem to realize HVDC network,
especially using a solid insulating material. In the case of power transmission cable, it was hard to develop a
good material for the insulating layer which was sustainable under DC high electric stress, and most of the
cable using an ordinary insulating material like XLPE couldn’t pass a DC test for cable. The reason of such fail
was thought as the accumulation of so-called space charge in the layer under high DC stress. To resolve such
problem, authors have been investigating the space charge accumulation characteristics in various polymeric
materials such as LDPE, XLPE and modified materials based on polyethylene using PEA method. From the
measurement results, we have encountered many curious space charge behaviors which were not expected
before the measurements. In this report, I would like to introduce these interesting characteristics of the space
charge accumulation behaviors observed in the polymeric materials under high DC stress at various
temperature.

insulation application; secondly the effects and mechanisms of adding nanoparticles and grafting with polar groups
in tailoring the properties of PP based cable insulation under DC electric field are discussed; thirdly, the space charge
performances under high temperature and high electrical field, are presented. Finally, the issues for future research
are introduced.

Interface tailoring for charge injection mitigation in insulators: different
principles and achievements
Professor Gilbert Teyssèdre
Laboratory of Plasma and Energy Conversion,
University of Toulouse, France
Synopsis:
In the development of HVDC technologies, one needs to handle the major drawback of insulating materials,
which is the accumulation of electrical charges forming internal space charge with possibly two major issues:
(i)- the out-of-control of the internal electric field distribution initiating current runaway and (ii)- cumulated
molecular level damages extending or creating defects and leading ultimately to breakdown. As regards
Polyethylene, which is the main material used in the insulation of HV cables, the efforts are directed to the
reduction of crosslinked by-products or even the replacement by thermoplastic polymers and/or
nanocomposites and more generally to the understanding of charge trapping processes in those materials.
At the same time, it is recognized that charge build up and even conductivity measurements heavily depend
on electrode conditions of samples and not only on bulk properties of insulations. To prevent space charge
accumulation, one necessary route, not examined in depth by the scientific community to date, is to control
the charge injection at the interfaces between the insulating material and the “electrodes” (metallic or semi-
conducting). Very few studies focus on the interface properties to change its characteristics in terms of charge
trapping probably because in a general way the phenomena at play are complex and not correctly described.
In this contribution, we investigated different routes for tailoring the interface between electrode and
polyethylene material, based on chemical modification of the insulation or layer intercalation. Three processes
were tested, going from grafting of polar groups, thick nanocomposite layer intercalation up to thin
nanocomposite layer deposition. Depending on the process, charge injection control is achieved either for
negative charges or for charges of both polarities. The process of charge injection control is discussed with
reference to the chemical/physical modifications brought about by the different treatments. The results
provide indication towards a strategy to control the charge injection in power cables and other electrical
components.

Developments in Functional Materials for Extended Performance Dielectrics
Professor Gary C Stevens
Gnosys Global Ltd,
The Surrey Research Park, Guildford, Surrey, UK
Synopsis:
Achieving high performance electrical power assets for higher voltage and higher ampacity applications in both
alternating and direct current networks requires dielectric materials with increasingly enhanced performance. This
lecture will examine a number of developments in functional materials that enable new materials to be formulated
that can meet some of the key challenges while enabling an appropriate balance of properties to be achieved.
Currently, these developments are informed by some a priori molecular modelling, multi-scale modelling and
simulation but also through the use of simple concepts based on experimental observation. We will illustrate this
using examples drawn from recent work on thermoplastic polymer blends, nanocomposite dielectrics and self-
healing materials having self-repair function.

Polypropylene Laminated Paper (PPLP) insulation for HVDC power cables
Professor George Chen
The Tony Davies High Voltage Laboratory
University of Southampton UK
Synopsis:
HVDC power transmission systems have received significant attention as they offer many advantages over HVAC
systems in terms of grids connectivity, system reliability and off-shore wind farms etc. As a result, HVDC power
cables have experienced a significant development in last ten years. Many efforts have been placed on developing
polymeric insulated cables. Insulation based on improved XLPE, nanocomposite and thermoplastic have been
developed for HVDC power cables at 400 kV and above. However, less attention has been placed on the insulation
based on polypropylene laminated paper (PPLP). PPLP has been widely used for HV power cables including HVDC
due to its excellent electrical and mechanical performances. Its use for power cable insulation can be traced back
to 1970’s, initially for HVAC cables but extended to HVDC cables. Typically, PPLP consists of a laminate of a
polypropylene film with a paper layer on both sides. This type of structure shows a higher AC, impulse and DC
breakdown strengths as well as lower dielectric loss compared with the conventional kraft paper. When compared
with XLPE insulation only limited publications on PPLP insulation are available in the public domain and the exact
mechanisms for the improved electrical performance are not well understood. When this type of insulation is
applied to HVDC cables above 500 kV, it becomes increasingly important to understand charge dynamics in such a
system and the influence on electrical performance.
