HID 1000KV-400pF Weak Damping Capacitor Voltage Divider

Mode: HID 1000KV-400pF
1) Weak damping capacitive voltage divider is consist 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 capacitors. 
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 is top electrode, which prevent abnormal flashover discharge when doing switching impulse test.
4) HV arm capacitor has 2 stages, each stage is 500kV 800pF.
5) Standard lightning wave:  ±1000kV
6) Standard switching wave:  ±220kV
7) HV rated capacitance: 400pF
8) Partial response time:　Tα≤100nS          
9) Over-shoot: β≤20%
10) Scale factor uncertainty:  Kε≤±1%
11) The square wave response characteristic meets the requirement of GB311 standard.
12) There are corona covers at the top of generator, corona cover’s cross profile is enough for 1.0MV positive switching impulse wave output.
13) Considering the transportation: the top electrode is field-installed. The material is stainless steel tube.
