“…Sustainable transformer operation is achieved by balancing the potential environmental risk, primarily due to mineral oil and impregnated paper used as insulation, with low-cost solutions for extending insulation life and reducing environmental impact. Transformer reliability depends on insulation system design and the ageing performance of insulating materials (Raj and Murugesan, 2022). Cellulose paper and pressboard provide electrical insulation and mechanical supports (Raymon et al, 2015).…”

Using mineral oil (MO) derived from petroleum, e.g., transformer insulation, raises environmental risk and affects sustainability. Due to its affordability and easy availability, MO will ineluctably be preferred over other biodegradable oils. Therefore, tools must be developed to recover aged MO, extend the life cycle, and increase its sustainability. The work presented here is aimed at the investigation of the electrical insulation properties of thermally-aged recovered-aged mineral oil (RAMO), as well as of aged cellulose pressboard impregnated by fresh mineral oil (FMO), aged mineral oil (AMO), and RAMO. The AMO is recovered using the combined adsorbents, A* and B*, which are Chitosan-activated Bentonite (CTN-aB) and Polyaniline coated Kapok Fibre (PANI-c-KPF) mix. According to FTIR, the recovered oil, RAMO, displays less C=C double bonds and carbonyl vibrations at 140°C, indicating lower oil ageing compared to AMO. The distribution of the crystalline and amorphous peaks is uniform for aged oil-impregnated pressboard (PB) with FMO and RAMO. Overall, it has been discovered that PB is impregnated with RAMO, resulting in an extended lifetime for the solid insulation. As a result, the increase in emissions slows down, and global sustainability targets are met.

“…This technique is more effective in identifying the interaction between different independent input variable towards output responses with the analysis of variance (ANOVA) suggesting the prediction of suitable model [23]. Raj et al [24] have studied the transesterification reaction of Pongamia Pinnata oil considering the parameters of time, temperature, catalyst where its optimization using RSM provided a higher breakdown strength and flash point with less viscosity suitable for transformer applications. Duraisamy et al [25] have studied the reclamation of transformer oil using different adsorbents and identified optimal amount of bentonite and kappa cotton using RSM improving its dielectric properties.…”

This paper reports the critical investigation on the streaming current of ester fluids towards power transformer. The optimization of benzotriazole (BTA) additive is tested based on the streaming current analysis considering its influence with and without the temperature. From the experimental results, the BTA concentration of 130 ppm on ester fluids observed a negative streaming current. The influence of temperature increases the streaming current of ester fluids.Only a minimal change is noticed in the viscosity of ester fluids with the addition of BTA but to the contradict, an increased dissipation factor is observed. The Response surface methodology (RSM) algorithm is being utilized as an optimization algorithm to identify the permissible level of BTA under transformer standstill and normal operating temperature conditions.
