Transesterification is a well known chemical process of producing biodiesel from edible and non-edible oils, animal fats and cooked oils. Base catalytic transesterification of non-edible oil is a popular method for production of biodiesel. Biodiesel production from Karanja or Honge (Pongamia pinnata) seed oil is gaining momentum in India and other parts of world. The real time monitoring of transesterification reaction progress is essential step towards automating biodiesel production. Two planar inter digital capacitive sensors (IDCS) are fabricated for the purpose of monitoring the transesterification progress of Karanja oil and their performance are evaluated. The repeatability and sensitivity of fabricated sensor is reliable and acceptable. The sensor with associated signal conditioning circuit will be useful in automating the biodiesel production process and play vital role in energy efficiency and the quality of end products.

The physical, chemical and electrical prosperities of MO is matched as an insulating material for transformer. Therefore, it can be used in transformers. Whereas, the MO is extracted from the fossil fuels. Due to vast consumption of fossil fuels, the accessibility of vestige fuel is going to run out near future. In addition, the MO (MO) is doesn’t meet the new environmental regulation due to it has less biodegradable. Therefore, this research proposed a new ecological friendly insulating oil for transformer which is renewable that of petroleum based insulating oil such as MO. Initially, a critical review has been made on recent development on alternate liquid dielectrics for transformer. Subsequently, critical characteristics of insulating oil have been measured according to the standard. Added to that, the critical characteristics of Natural Ester Oil (NEO) are estimated at diverse temperatures from 50°C, 70°C, 90°C, 110°C, 130°C, and 150°C respectively.

The insulation condition of a transformer decides the longevity of the equipment. The unpredicted failure of power transformer will lead to major disaster in the distribution network and it affects both environment and public safety. Nowadays synthetic oil and natural esters are alternatives to transformer oil because of the biodegradable nature. In this paper, investigations were carried out to study the performance of the blended ester. The different properties investigated were viscosity, breakdown voltage, flash point, dielectric dissipation factor and moisture content. Comparisons of the properties were made between mineral oil, vegetable oil without additives and with additives. Further Investigation was carried out to study the impact of antioxidants and degasification. The results indicated that the addition of antioxidants and degasification of the vegetable oil improve significantly its voltage withstanding capacity. The Indigenous oil is code named as DM; Indigenous oil with DBPC is codenamed as DM1, Indigenous oil with BHA is codenamed as DM2. The results have been tabulated and found to be satisfactory.
