The GAS Discharge Tube has not found the way has not found the way into Tesla Coil designs. Latest design from Bourns does prove the opposite as possible. Our goal is to produce a high voltage power supply. In my demonstration I achieve 100 KV very easy and save.

We integrate our measurements into the formula
GDT – 3600 V
NST = 40 volt, 20 Watt
Spark Frequency 50 Hz
Hv Transformer = 12 Volt, 250 mA = 3 Watt
Spark Frequency 7 Hz
Spark Gap 3,5 cm
Humidity 40%
Lap Temperature 18 Degree Celsius
100 KV, Air Voltage Breakdown 1 mm per 3000 Volt
Rectified via a High Voltage bridge rectifier is 1.44 times RMS or 140 KV DC

Summary
The GDT is mainly a precision voltage breakdown device for regulating voltage and
current. Most of them are only to be used in circuits where the condition is only briefly met. However the 2975 series from Bourns is designed to work continuously in high voltage tank circuits. The arrangement as shown in the diagram before is simplistic and does not suffer from overheating devises. However for long term use a heat dissipation system need to be applied. Either direct via clamping copper blocks on each electrode side and using a water cooling system or by embedding the whole device into an transformer oil bath and cool the whole bath as done with any high voltage transformer in power plants. The designed GDT in use will ignore any change in voltage and current and only lets the design values path. To increase the breakdown voltage GDTs can be mounted in series. For increasing life and security devices can be installed in parallel. That has no impact on the second device. It will not conduct unless the first one is defect. It does not behave like a resistor in the circuit.
