SF6-Air leak pointer for Very High Voltages

SF6-Air leak pointer for Very High Voltages

Sep 01, 2008On the other hand, the conductor on the right, with its rounded tip, will have very little leakage and will stand off much higher voltages. Solder joints are always a trouble spot in high voltage circuits. In one instance I designed and constructed a 10,000 volt DC power supply for an industrial flash unit.
