Besides, there is another equipment using hihg voltage. The high voltage divider is a special instrument for on-site measurement, which can measure both DC high voltage and AC high voltage. The whole equipment consists of a voltage divider and a measuring instrument. The voltage divider adopts a balanced equipotential shielding structure, and high-quality electronic components are used inside the completely sealed insulating cylinder, so that the entire device has accurate testing, good linearity and stable performance.
