Smart LV distribution system will have numerous low-power distributed energy resources (DERs) in form of rooftop solar PV systems, grid-tied inverters, ...etc. These DERs will be responsible for power backup, power trading with distribution grid, and local reactive power support. The characteristics of these power resources is that they will work from smaller PV installations with 1-5 kW rating or lower. This talk concentrates on the power converter topologies and control suitable for these smaller installations. Apart from discussion about conventional Voltage Source Inverters, this talk will explore alternate topologies and their control suitable for future smart LV distribution system.

The talk looks at two most widely used approaches for Bulk Power Transmission at High Voltages viz: HVAC and HVDC. Advent of Power Electronics with High Voltage Capability has not only ...enabled HVDC Transmission but also enabled better and stable operation of HVAC Networks through FACTS. The talk attempts at covering various techniques employed to develop large grids across continents forming regional grids beyond a single Nation. These may perhaps in future evolve into a Global Grid. One grid across the world.
Electricity is perhaps one of the greatest gifts of Science to Humanity in 19th Century. Electric Power is the third most important commodity, next to only Air and Water. Hence, a continuous and reliable power supply is very crucial to our survival and development. In fact, index of development of any country is in terms of per capita energy consumption. The highest level of transmission in Indian Sub continent is decided as 1200 kV class (HVAC) and + 800 kV HVDC.
Power Transmission began with Edison’s DC system for Street Lighting the Perl Street in New York. Invention of Transformer by Tesla revolutionized Power Transmission with ability of stepping up and down of voltages. Adoption of Synchronous Machines as Generators with Coal based Steam Turbines as prime movers and Three Phase Induction Motors as common Rugged application for all forms of Drive gave a Philip to HVAC transmission systems – levels reaching up to 1200 kV. Developments in Solid State Power Electronics and need for transmission of Power with low Rights of way, below sea, large river crossing and Asynchronous operation of AC Networks brought in HVDC Links, HVDC Bulk Power Transmitters and MTDC lines to fore front. India is proud to have the first MTDC line in the whole world at +800 kV. Developments in HVDC Power Transmission as Power Electronics Developed lead to a possible application of HVDC Technology to Power Compensation and Stability through Reactance Control or Reactive Power Control termed Flexible AC Transmission Systems FACTS.
Turn of the century in the year 2000 brought in need for looking at implementing and looking at Clean Energy Resources termed initially as Non-Conventional Energy Resources or Renewable Energy Resources as Known today. The two most widely exploited renewable energy resources are Sloar Photovoltaic Based Generation and Wind Turbine Based Generation (on Shore or Off Shore) mostly being complementary in nature – Sun being available during the day and wind during the night. Another segment that has gained prominence in use of Renewable Energy resources is Transportation Sector known to Electrical Engineers as field of Electric Vehicle (EV) technology.
With all these developments it is envisaged that large regional grids also termed Mega Grids are possible in near future. In fact Indian Grid which was five regional Grids in the year 2000 is now one with connections for import/export to neighboring countries viz: Bangladesh, Bhutan and Nepal. A submarine to Mauritius is being envisaged. Experts predict thus possibility of a Global Grid across the planet Earth.

Transformers are not only critical components but also very expensive power system equipment. Large number of power transformers, which have oil-paper as the insulation, have already crossed their design life,... but are still working fine. The strategy for health management of transformers is therefore of immense economic importance to power utilities all over the globe. Such strategy depends on monitoring of condition of the insulation. Condition monitoring is best performed if it is non-invasive in nature and if it could identify the ageing status of the most vulnerable insulation, viz. paper. The contaminant that damages paper insulation most is moisture. Hence, a good condition monitoring technique for transformers is the one that could estimate moisture content in paper insulation accurately, which requires a proper understanding of moisture dynamics within the transformer insulation.
The following will be discussed in the Tutorial:

Over the last 50 years, the branch of high-voltage (HV) engineering called “electrostatic processes” has provided the foundation for extraordinary, new industrial developments measured in billions of U.S. dollars. All these processes make use... of the forces that may be generated in a high-intensity electric field. The range of applications extends from electrostatic painting to the separation of granular mixtures in the recycling industry, and from air filtration to waste water treatment [1, 2]. Electrostatic techniques serve also to remove unwanted electric charge and prevent the related hazards [3].
This presentation is aimed to introducing to the HV scientists and engineers attending this tutorial some of the electrostatic processes developed by our research team at the PPRIME Institute, on the campus of the University Institute of Technology in Angoulême. With more than 600 scientists, doctoral students, engineers and technical staff, PPRIME Institute is the largest research unit of the French National Center for Scientific Research in the field of physical sciences for engineers. The PPRIME’s research team directly involved in the present study has a world-wide-recognized expertise in electrostatic processes, as demonstrated by hundreds of scientific publications, more than 40 PhD theses, tens of industrial partnerships and two patents active in most of the countries in the world.
The use of high-intensity electric fields for sorting the constituents of granular mixtures is the class of electrostatic processes on which most of our investigations have been focused. In our talk, we will introduce the principle of operation of these devices and give some hints on the HV experimental techniques that we are currently using. After a brief presentation of the main applications of the electrostatic separation in the recycling industry, we will expose in more detail the techniques that are specific to the treatment of waste electric and electronic equipment.
To illustrate the diversity of high-intensity electric fields applications, we will also describe the use of: (1) AC HV for the generation of dielectric barrier discharges for the depollution of water and the modification of the tribological characteristics of polymers; (2) DC HV to produce corona discharges for the precipitation of dust in industrial effluents and for improving the performances of electret filters.
In the end, we will discuss the perspectives of expending the range of industrial applications of the HV engineering techniques designated as “electrostatic processes”.

Partial Discharges (PD) are in general a consequence of local electrical stress concentrations in the insulation or on the surface of the insulation. If it remains undetected, then catastrophic failure may happen leading to severe financial... losses as well as outage of power supply. It is important to understand the subtle differences between Partial Discharge and Corona Discharge. This talk will highlight how the Dielectric Strength of a Gas vis-à-vis Pressure plays an important role in PD phenomenon and hence what are the sources of PD. The goals of PD measurement will be discussed with a focus on the physical effects of PD. PD detection through electrical measurement based on IEC 60270 and thereafter non-invasive measurement of PD based on ultra high frequency and acoustic sensors will be explained in details. Major quantities related to partial discharge pulses and display of PD pulses will be outlined. PD Pattern Analysis in GIS along with Trending of PD Pattern will be taken up as case studies.
