Re: [TCML] Do over capacitance lead to poor resonance?

Sounds like you might have a bad capacitor. The rating is too low at 15KV. I have seen primary resonance go as high as 7X, but 2-4X is more normal. My first coil was a 6/30 design and it would blow 15KV ceramic caps like firecrackers. I would double that 15KV value.

Make sure you are using a repetitave pulse capacitor. If you look at the specs, make sure it can handle more than 100 pulses per second for 50 Hz.

Everything else sounds sounds OK. With the higher than LTR value, it means you will need to tap a little further in on the primary. The LTR value works best with syncronous rotory spark gaps.

If you are tunned properly, you should get around a foot of spark length.

Hi coilers,

I have tuned my tesla coil months and months,
However, it don't give any open air discharge and corona.
After I have tried my effort on tuning the secondary coil and primary inductance,
I am thinking if too much capacitance would be the cause?

Here's the case,
I am using a 7.5kV 30mA 50Hz Neon transformer,
as stated by Teslamap,
the capacitor should resonant at 12.7nF, LTR static 20.6nF.
However my capacitor rated at 15kVDC 22nF.
Would this greatly effect my coil and don't let it give out streamers?
