This is so offensive. I want this thread to be completely removed please.

If worked, then the probe has problem and must be changed? If still didn't discharge, power supply has problem? There is a one k ohm resistor between the power supply ground wire and the ground electrode of device. high voltage probe connected to oscilloscope through 50 ohm connector. the...

There is a one k ohm resistor between the power supply ground wire and the ground electrode of device. high voltage probe connected to oscilloscope through 50 ohm connector. the device (plasma jet) made up of: SS 3 mm diameter rod connected to high voltage inserted inside a quartz tube with 4...

power supply: https://www.amazing1.com/hv-hf-power-supplies.html#HVHF oscilloscope: Tektronix 4 channel. then what shall I do to resolve overloading?

Then what this shows if I disconnect the probe and get discharge? and if I disconnect probe and do not get discharge, what this shows?

did not check that really!

The problem is I do not get any discharge, while such voltage must breakdown the gas! I use a high voltage probe to see the voltage on the oscilloscope. The ampere meter on the power supply does not show anything. The only thing I can see is the manually adjusted (30 kV) voltage on the power...

Using a high voltage probe.

I am using a power supply (30 kV, 20 kHz) to discharge in air between two electrodes separated by an insulator. For 30 kV applied voltage, oscilloscope shows only 6 kV, and no discharge occurs. What are possible problems and solutions?

Pulsed as opposed to continues. Apply voltage with specified repetition rate.

If correct, then how pulsed increases the efficiency?

With DC, gas breaks down, but charges are accumulated on insulator and opposite electric field is generated, then no plasma! But AC, polarity changes and this problem resolved.
