I > suspect dust or some variable > is greatly affecting the breakout point. ---- Important variable might be impulsive character of TC impulses as well.In other words :time and shape of pulse.Both affect conditions that maintain development of selfsustained discharge . For example,one may get higher results for breakout voltages when bps are low in comparation with CW operated TC.Also ,for small diameter smooth sphere breakout point, max field required is more than 30 kv/cm (standard conditions given). Still,70% discrepacy seems too high to me anyway. Good news:with your OLTC system you will be able to control and vary the excitation parameters at will and see how things change. regards, Boris __________________________________________________ Do you Yahoo!?
