9kV 50mA tesla coil NST question. Why does the circuit breaker in my home trip when i plug in my NST? Answered
please someone help, this is my first tesla coil project, my setup:
230VAC 50Hz input
ricci 9000v 50ma NST with a built in GFI (ground fault interrupter) but i bypassed the gfi succesfully .see pics
7,5 cm diameter pvc secondary
1000 turns #24 magnetwire (0,5mm) secondary
10 turns 8mm copper pipe primary (tapped at 7 turns)
saltwater capacitor 16 green beer bottles in a bucket with a capacitance of 0,0122 uF or 12,2 nF (thegeekgroup bucket cap)
static spark gap 28mm diameter stainless steel spheres as electrodes with oven fan (temporary, i am building a hyperbaric gap)
10cmx27,5cm aluminum toroid topload with a brass screw as breakout point
RF ground aluminum rod 1,2 meter
When i tested the coil for the first time the spark gap was set on 6mm and i got 20cm or 8inch streamers without breakout point but the gfi on my nst tripped after a few seconds.
i didn't know there was a built in gfi on my nst so i fooled around with my spark gap and safety gap and the tapping point on the primary hoping to get better performance. after a few runs the gfi started to trip very fast and i could only run the coil with the spark gap set on max 2mm, any bigger then that would trip the gfi on the nst. so i found out that it had a gfi and i bypassed it with thick wire. Then when i ran the nst i got the exact same thing but with my circuit breaker in my home. i have made a video on youtube that shows the problem here is the link: (please help)
please anyone help me! Any help or suggestion is very welkom!
