Non-destructive dielectrometry measurement techniques such as polarisation and depolarisation current (PDC) measurement is gaining popularity in power industry to evaluate the insulation condition of transformers. Due to nature of the polarisation species involved in transformer insulation, a perfect PDC measurement would take a very long time, to allow all(More)
Dielectric testing techniques, in both time and frequency domains are currently being widely used by the power utilities for the assessment of the condition of transformer oil-paper insulation systems. However, it has been reported that the results of these tests are highly influenced by the operating temperature during the measurement. The distribution,(More)
With the advancement in digital technology, diagnostic techniques based on dielectric relaxation methods e.g. frequency domain spectroscopy (FDS) are currently being widely used by the power utilities for the assessment of the condition of power transformer oil-paper insulation. However, it has been observed that the results of these tests are highly(More)
Temperature affects the mating displays of many ectothermic animals, yet almost no information exists on the temperature preferences of ectotherms while they are displaying for mates. This study investigated the preferences of displaying male field crickets (Gryllus integer) for microhabitats of different temperatures. G. integer males attract sexually(More)
Dielectric testing techniques such as frequency domain spectroscopy (FDS) is currently being widely used by the power utilities for the assessment of the condition of transformer oil-paper insulation (OIP) systems. However, it has been observed that the results of these tests are highly influenced by the operating temperature as well as the ingression of(More)
