Construction and operation of a valve arresters VBOs



Valve discharger VBOs consists of the spark gaps (1) and nonlinear resistors (2), enclosed in a hermetically closed porcelain lid (3), which protects the internal elements of the arrester from the external environment and provides stability characteristics.
Working resistor spark gap made of Sparkasse "Visit" and has a nonlinear current-voltage characteristic.
