● In order to facilitate the needs of different measurement on site above 300kV voltage divider is designed into the structure of double sections or three sections it realizes multi-purpose and more convenient to carry;
● When semetal structure using one section to measure low voltage using two sections to measure higher voltage and using three sections to measure full-scale voltage;
● Filling with imported dry polymer materials as insulation material which makes the product have smaller structure lighter weight higher reliability and the internal partial discharge is reduced to the lowest value.
● AC/ DC automatically changed with functions of over-voltage protection and high voltage flashover protection.
● Using low temperature coefficient of resistance and capacity components there is no adjustable device on the low voltage arm then there is no vibration to affect the precision.
● The measurement system and the high voltage part is completely separated absolutely measurement is safe and reliable.
