Title: Fun Stuff with HV Post by: N4zed on July 24, 2015, 04:44:19 PM I didn't want to hijack the fuse thread so here are a few ideas for fuses....LOL
These guys are having fun: https://www.youtube.com/user/Photonvids (https://www.youtube.com/user/Photonvids) Watch the trailer in the center for an overview....

One kind is just a bifilar air core solenoid of wire that will carry the current. It acts as a transformer. One winding is in series with the lamp and the other is in series with an ignition transformer and a spark gap. The lamp is started by the voltage from the high frequency low power arc. Low power meaning power level in relation to the lamp power. In the high current DC supply that runs the arc is usually some sort of protection diode or device to direct the residue of the starting current away from the arc current regulator.

And these guys have access to 3 phase power?? Title: Re: Fun Stuff with HV Post by: N4zed on July 26, 2015, 11:07:42 AM 220 is standard in EU .. I think.
The real question is how is he holding a metal rod or box knife in his bare hands and shorting out the HV ??!!! ??? ??? ??? :o :o :o :o Title: Re: Fun Stuff with HV Post by: SM6OID on July 26, 2015, 10:30:31 PM 230 is The nominal mains voltage.
Title: Re: Fun Stuff with HV Post by: W2PFY on July 27, 2015, 08:27:43 AM 230 is The nominal mains voltage. He in the US we have single phase with 120 volts to center tap on the pole pig or 240 across the transformer to run our electric stove, water heaters etc. Do you have just one 230 lead or is it 460 volts total like the US. I guess you never have a problem with 60 cycle hum in most EU countries?

These guys are crazy Title: Re: Fun Stuff with HV Post by: SM6OID on July 28, 2015, 03:50:39 PM Hi! AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
The "household" mains outlet voltage in Europe is 230 V / 50 Hz. In Sweden we have 230/400 V three phase. (not sure about other countries) Between phase and neutral = 230 V. Between phase and phase = 400 V. Normally a mains outlet is fused to 10 A. (slow blow) If you have a house, you have a 230/400 V feed, at least 16 A. Even some apartments has got a 230/400 V 16 A feed. (!) Needless to say, it's quite nice to have a 400 V three phase feed to the transmitter! I've got a Harris RF-130 with the three phase power supply, flickering light is not a problem. But, when I'm on the air with some of the other TX's that likes 10-15 A @ 230 V, flickering lights is a bit of a concern. |
