HCG 3000KV-400pF Multiple Chopping Gap

Mode: HCG 3000KV-400pF
1) Weak damping capacitor 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 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 are top electrodes, which prevent abnormal flash over discharge when doing switching impulse test.
4) Standard lightning wave: ±3000kV
5) Standard switching wave: ±2000kV
6) HV rated capacitance: 400pF
7) Partial response time:Tα≤100nS 
8) Over-shoot: β≤20%
9) Scale factor uncertainty: Kε≤±1%
10) Capacitor voltage divider equip with two low voltage arms, voltage ratio is 2000, 4000 respectively( Supply national calibrating certificate)
11) The square wave response characteristic meet the requirement of GB311 standard.
12) There are corona cover at the top of generator, corona cover’s cross profile is enough for 3000kV impulse wave output.
13) Considering the transportation: the top electrode is field-installed. The material is stainless steel tube.
