II. Electrical parameters:
Rated withstand high voltage :10/20/35 KVAC;
Impulse voltage: 80/120/210 KV;
Rated Low Voltage Signal (or self- determined)6.5/3V;
III. Electrical schematic:
The product is designed by the principle of capacitor partial voltage, the primary capacitor is high voltage ceramic capacitor, which is used to collect voltage signal; the secondary capacitor is low voltage ceramic capacitor, and the secondary large capacity capacitor is used to divide voltage to obtain a small voltage signal.
High voltage end Vin is connected with the measured signal, low voltage end is the shielding line, the red line of the shielding line is the low voltage signal, and the black line is the ground wire. The two low voltage lines are connected with the acquisition system for data analysis and processing.
V. Data analysis:
The voltage divider for this design uses a variable ratio of 2664, or 2664 times the recorded low voltage data, which is the actual data on the high voltage side.
