Re: [TCML] LTR/STR and spark length

Hi David,

A wide gap increases the voltage to arc the gap (do not doubt this), but it doesn't mean that the larger bang energy will run more efficiently across the gap. The gaps ability to process that energy with low losses is what makes it "good" or "not". Opening the gap is usually a start to destruction in my opinion. However, if the gap runs hot, the arc voltage is simply lower and they get away with doing it (meaning not killing the transformer or cap), but since the arc voltage is lower due to a lower voltage, no bang energy increase (expect maybe at the first few sparks).

If the gap is adequately design to handle the power, then opening the spark gap would certainly develop a large bang size and increase spark length (up until the transformer or cap died which could be seconds or several minutes of run time).

Temperature, bang energy, and geometry are very important in my opinion with regards to a static gap of any type (and they are interrelated).

Take care,
