Abstract
The crystallinity of several dielectric liquids at low temperatures used as capacitor impregnants was investigated by means of DSC (differential scanning calorimetry), and some of the results obtained are compared with those obtained by the traditional glass-tube test. Compared to the glass-tube method, DSC has the advantage of fast measurement speed. Further research results on the partial discharges of model capacitors (all-time capacitors and paper/film capacitors) impregnated with the dielectric liquids tested show that the DSC method is practicable for measuring the properties of dielectric liquids at low temperature.<>
