“…The inverter surge voltage is characterized by the waveform parameters of rise time (0.04-1 μs), repetition rate (1-20 kHz), impulse duration (0.08-25 ms), shape (square or triangle) and polarity (unipolar or bipolar) [5]. Figure 2 depicts an enlarged waveform of the inverter surge voltage and the resultant PD signals measured with a photomultiplier tube, where PD was detected at both the rise time and the fall time of the inverter surges [6].…”

This paper reviews the up-to-date research activities on electrical insulation techniques under repetitive surge voltages with steep wavefront for low voltage inverter-fed motors. Partial discharge (PD) inception, propagation, ageing and breakdown characteristics of magnet wires, including recently developed PD-resistant wires such as nanocomposite enameled wires, are described. PD measurement techniques under the steep-front voltages and IEC activity toward their standardization are also introduced.

“…Currently more research is going on the effectiveness of nanofillers. It has been already proved by many researchers that when the sizes of nano fillers are very less, the interaction zones are so large that they start to interact at very low level of loadings [3]. The interactions between polymer matrix and nanoparticles alter polymer chemistry, i. e. chain mobility, degree of cure and generate new trap centers in the composite which brings about the significant changes in electrical properties [4].…”

-The polymer nano composite possess good priority recently for engineering applications.Especially the electrical insulating materials attract the high performance of nano composites. In this work the ballmill synthesiation process of nano sized Alumina (Al 2 O 3 ), the preparation of new nano composite material with an content of enamel and synthesized Alumina as 1wt%, 3wt% and 5wt%. Experimental investigation has been carried out for the prepared nano composites materials with respect to dielectric parameter measurements such as dielectric loss (tan δ), dielectric constant (ε), dielectric strength under various temperature. The partial discharge level also measured for all the samples and the PD inception voltage is also observed and compared. Weight loss of the material has been analyzed through TGA. It has been experimentally proved that 3wt% of Alumina nano filler added enamel has significant improvement in the dielectric and thermal properties.

-In recent days, there was a significant development on the electrical, thermal, mechanical, physical, chemical, magnetic and optical properties of the polyamide enamel, varnish and other insulating materials by the addition of nano fillers to it. Enamel was used in High Voltage Apparatuses used in Medical Electronics as insulation. Insulating materials determine the life time of the electrical apparatuses. The life time of the insulating materials was improved by the addition of nano fillers to it. Hence the life time of the electrical apparatuses was improved by the mixing of nano fillers to the enamel. In this research, the basic dielectric properties of the enamel and enamel mixed with nano composites of silica and alumina were analyzed and compared with each other. The addition of nano fillers has improved the quality factor and capacitance of the enamel. It was also observed that the addition of nano fillers has reduced the dissipation factor and dielectric losses of the enamel. Heat produced by the dielectric losses was also reduced by adding nano fillers to it.
