Hi,
I have a small transformer, it will generate high voltage, using voltage doubler (Diode + cap), the voltage is about 1.5~2KV DC. the circuit is similar to neg ion generator, where voltage is high but current is very small.
The application is to test insulated of magnet wire, high voltage is applied to the wire and conductive brush, if insulated of wire is bad, it will sparking.
Now I need to detect if the HV is short or sparking , how to convert the spark or short to logic, so I can interface it to PIC MCU?
Thank you,
