Principle of tanδ measurement in liquid dielectric is introduced using rectangular waveform voltage. Technical key to realization of the measurement is analyzed. With respect to time approaching a stable measured value in the measuring system
control in measuring time
set up various parameters in the system
and instrument selection for current measurement
calculation method and solutions are proposed based on successful experiences. And these methods are proved to be an effective way to measure low tanδ of liquid dielectric with better measurement resolution and accuracy.
