The basic measuring circuit of this method includes the AD515A and a integral capacity, it not only enhances the measuring stability but also makes the calibration and the adjustment more convenient.
The paper analyzes origin and connotation of thermal stabilitycalibration formula from basic concept of insulating conductor thermal stability, and discusses some means for thermal stability.
A standard impulse signal generator with high stability is an important equipment for routine test and calibration of digital recorders for measurement in high-voltage impulse tests.
