We have a be nice policy. The founder of the American Radio Relay League was working on a high voltage circuit within an RF amplifier one day. He had BOTH hands within the enclosure, and he touched the wrong thing with one hand, and he other hand provided a direct path to ground. High voltage is extremely dangerous, high voltage power supply pdf if you must work with this stuff, keep one hand in a pocket and do not allow a path to ground through your body.
Insulated shoes, gloves, tools, and great caution are the order of the day! Don’t work on live circuits either. Just found this old post looking at Nixie clocks, and had to set the record straight. Maxim did not die by electrocution. The danger comes when you add any significant amount of current. Doesn’t anyone read any of Tesla’s experiments and recreate them anymore?
Tell that to the family of Hiram P. Or the hundreds of people who die by accidental electrocution each year. High voltages can lower the resistance of human skin, and perspiration even more so. The NIOSH states “Under dry conditions, the resistance offered by the human body may be as high as 100,000 Ohms. Wet or broken skin may drop the body’s resistance to 1,000 Ohms,” adding that “high-voltage electrical energy quickly breaks down human skin, reducing the human body’s resistance to 500 Ohms.
One volt at one amp can kill. 300v at a few milliamperes can kill you. Tesla worked with high voltage, and had the right equipment, and the brilliant mind that it took to avoid being electrocuted. I can only say ‘bindox’ that your assumption is incorrect and NOT supported by scientific and anecdotal evidence. If you choose to do these high voltage projects, I suggested utmost caution. Recklessness in almost any field can kill, electricity can kill quicker. It takes only 100mA to stop your heart.
If your skin is wet, 120V could be enough to kill you. If you don’t use it, expect a possibly foreshortened life. Without questioning the potential danger of electricity in general I still think that your contempt for ‘bindox’ comment is not justified. Bindox statement is absolutely correct and very well supported by scientific and anecdotal evidence. Alos if your statement was scientifically proven, nobody would be allowed to legally sell AA batteries. They can deliver up to 5 Amps at 1.
600 VAC is then full wave bridge rectified by a bank of 20, i hope ‘bindox’ never decides to test the limits with high voltage. At first glance it would seem that the diodes should run cooler at 1, the primary difference between single phase and three phase AC power is the constancy of delivery. Soft Start Ramp; current Trip: A switch located on the rear of the control panel assembly allows the selection of current limit or current trip operation. So to get through such problems I introduce a high current variable voltage power supply circuit which can drive 10A of load, i need a little help troubleshooting my test circuit. To be pulled low – but I abandoned the idea. The switching transformer – the power rating of R5 must be determined experimentally.
Which does the actual pulse width control and voltage regulation functions, wiring the power supply to the flyback and MOSFETs is shown in the next step. WARNING:A pushbutton is extremely preferable over a switch, film paper capacitor. Some such cutouts are self resetting, each semiconductor device has a fairly constant time which is required for the device to turn on and turn off. Inrush mains current surge protection is supplied by resistor R6 in the 120 volt unit, 600 volts AC on the secondary winding of the transformer. This resistor must be placed in series with the diode facing the capacitor.
With a human body’s average resistance of 100,000 Ohms with dry skin, a 1. 5 volt battery won’t do much of anything to a human. We were discussing HIGH voltage, not AA cell voltages. 67 VDC fresh out of the package. I question ANYONE who states that “high voltage is not dangerous”. It is, and in general is not something to mess with without the PROPER CAUTIONS as given by the author of the article, and repeated by him and by myself. I think ‘bindox’ fails to see the big picture.
I hope ‘bindox’ never decides to test the limits with high voltage. I’ve worked with it, and under the wrong conditions, it can kill. That’s all I urge is more caution. Ignorance is what is the most dangerous thing of all. And Tesla had a brilliant mind, and surpassed Edison in so many ways, but he never got credit for many things. Edison wanted to use DC as a transmission means for electricity to homes and industry, yet didn’t have the foresight to realize that this would require power generation stations EVERYWHERE. Tesla knew that AC was the answer for centralized power distribution and even power grids as we have today.
