HID 400KV-400pF Weak Damping Capacitor Voltage Divider

Lead time: 30 days

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