Mode: HID 900KV-400pF
1) Weak damping capacitive voltage divider is consisting of series connection multistage pulse capacitor.
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 flashover discharge when doing switching impulse test .
4) lightning impulse wave: 900kV
5) Voltage ratio: 3000:1
6) Uncertain of measurement <1%
7) HV rated capacitance: 400pF
8) Partial response time: Tα≤100nS
9) Over-impulse: β≤20%
10) Synchronous rate : >2%
11) The square wave response characteristic meet the requirement of GB311.
12) There are corona cover at the top of generator, corona cover ’s cross profile is enough for 900kV impulse wave output.
13) Considering the transportation: the top electrode is field- installed. The material is stainless steel tube.
