Recently authors have proposed damage equalization method with step-stress tests for quick estimation of life exponent of power equipment insulation. Traditional constant-stress accelerated ageing tests for insulation are disadvantageous since outliers in sample data will always be there and some samples may not fail even after a long time. Such long duration life estimation tests are a major bottleneck...
Insulation in electrical equipment is a very crucial aspect while designing any electrical system especially in case of high voltages in any part of a power system. Hence it is crucial to determine the properties and performance of an insulating material. The experiments deal with the measurement of breakdown voltages and determination of ageing of an insulating material under accelerated AC fields...
Conventional constant-stress accelerated ageing tests are time consuming, cumbersome and suffer from the disadvantage that some samples may not fail even after a long time. This necessitates censoring the data for life estimation, increasing the complexity of data analysis and leaving some amount of uncertainty due to censoring. Step-stress breakdown tests for life estimation were already proposed...
This paper presents methods for forecasting solar power generation by a solar plant. Solar power generation depends primarily on relative position of sun and some extrinsic as well as intrinsic factors. Extrinsic factors such as cloud cover, temperature, wind speed, rainfall and humidity have been used with intrinsic ones such as degradation of solar panels as inputs for proposed techniques for generation...
The Pulsed Electroacoustic method has been widely used in research labs and industries for space charge measurement for quite some time. Due to its robustness and simplicity it has attracted great attention of researchers. Various models of PEA system have been reported using numerical simulation and COMSOL to address issues related to charge signal. Recently, the authors have reported a PSpice model...
Pulsed Electro-Acoustic Method is widely used for the measurement of charge in polymeric insulation. The method is based upon the generation of acoustic wave proportional to charge and pulsed electric field. This acoustic wave traverses several material layers before being sensed and converted to electrical signal by a piezoelectric transducer. Due to multiple reflections in its path a direct analysis...
