HID 1200KV-400pF Weak Damping Capacitor Voltage Divider

Mode: HID 1200KV-400pF
1) Weak damping capacitive voltage divider is consisting of series connection multistage pulse capacitors.
2) Damping resistor is multistage distributed; the capacitor is non inductance structure,low voltage arm is parallel connected by no inductance capacitor.
3) The high voltage arm capacitor is installed on the high mechanical strength movable metal base;the wheels on the movable base are made of polyurethane material with fixed brace.There are top electrodes, which prevent abnormal flashover discharge when doing switching impulse test.
4) Standard lightning wave: ±1200kV
5) HV rated capacitance: 400pF
6) Partial response time: Tα≤150nS                                  
7) Over-impulse: β≤20%
8) Scale factor uncertainty: Kε≤±1%
9) Voltage ratio: 3000:1
10) Divider ratio accuracy: <1%
11) The square wave response characteristic meets the requirement of GB311 standard.
12) There are coronas covering at the top of generator, corona cover’s cross profile is enough for 1200kV impulse wave output.
13) Considering the transportation: the top electrode is field-installed. The material is stainless steel tube.
