High-voltage dischargers (arresters) A high-voltage discharger is a device designed to switch electrical energy due to electrical breakdown of an insulating medium. This is a device that instantly changes its electrical conductivity when a discharge occurs between the electrodes.

ASD (air-spark discharger), can be produced as controlled (with a middle electrode) and not controlled.
We can also offer air spark dischargers with the following parameters:
1. Range of switched voltage 0 ... 125 kV. 2. Range of response time 50… 300 ns. 3. Range of self-inductance 30 ... 300 nH. 4. Range of pulse repetition rate 0… 1000 Hz. 5. Energy range per pulse 0 ... 100 kJ. 6. Range of discharge current 1 ... 1000 kA.
The dischargers are used as high-speed switches in pulse current generators, communication devices, location devices, nuclear and experimental physics, etc. According to the principle of operation, dischargers are divided into:
-controlled, i.e. triggered at a given time from a control action (electrical impulse, optical or ionizing radiation); - not controlled, statistically triggered after reaching a certain voltage level on their electrodes.
Controlled dischargers find wider application. The dischargers can be classified according to the type of dielectric: -gas dischargers of atmospheric and high pressure (spark); -low pressure or vacuum dischargers; -the dischargers with a liquid dielectric; -solid dielectric dischargers, which usually use synthetic films with high electrical strength.
The most widespread at present time are air-spark and vacuum dischargers. The advantages and disadvantages of various dischargers are shown in the table:
