Trust me the ADD and Invert work perfect when probing into unknown territory. In high school (1970's) we were taught differently and will not go there do to liability but is does work and prefer not to use that method. It wasn't until I acquired a Tek 7854 which had a differential plugin only to find out later when someone showed me this method the plugin is not needed on a dual trace with ADD and channel 2 Invert. Just remember like this gent said if you were wanting to look at a phase in a motor controller even at just 20 amp fused that ground lead at 16AWG at best will pretty much explode in your hand and molten copper slung everywhere along with melted insulation. Also good 10X probes are not a bad idea either as most budget scopes only go up to 10 volts per division. Good job with the video.

I'm currently a year 2 mechatronics student at BTC!! I found one of these in our trash bin and I've been cleaning it up and playing with it, and look what I stumble upon in researching it! If you are who I think you are, we used your EE textbooks and coursework last year and it was really good! o7

Good God , worked with the 13A all over the world , that was when the US was at the front of technology

cool

what i don't understand, why an NC contact is a not true once it allows current through and make the output true energized, ? i understand is the opposite of the NO, ..., but i found several videos with Nc Stop button once open once closed, ...?

I have a question that has been bothering me: after changing the settings of the protection relay, do I still need to conduct a test? For example, the overcurrent protection has been changed from 5A to 6A. Do you still need to test the relay protection? Thank you

any tips on plug/seat lapping such valves?

It would be very informative if it’s possible to make demonstration when water level goes below water pump level and how to provide suction when water level is below pump

I got confused by this so I asked ChatGBT to describe to me the difference like I'm 5 years old! Hub: Imagine a big classroom where the teacher (the hub) shouts every message out loud to everyone in the room, even if the message is only for one person. Everyone hears it, but it might be confusing or noisy, because every message goes to everyone, even when it's not for them. Switch: Now imagine a smart teacher (the switch) who knows exactly which student the message is for and whispers it directly into their ear. Only the person who needs the message gets it, and it’s much quieter and faster for everyone else. In short: Hub: Yells everything to everyone. Switch: Sends the message only to the right person. Switches are like smart helpers who make things quicker and easier by only sharing what’s needed!

Great thanks for explean expermantal the cavation

Did this with my first pull. Good video, works well. Thanks.

What kind of generator did you used?

Camera op should stop drinking

Thank you

you need to connect a 250ohm resistor in series for this, no?

Is the signal generator and oscilloscope Both terminated at the entrance or positive lead of the cable ?

Interesting video! I never saw a switch taking 5 minutes to update it's mac table. Is this a cheap netgear issue? Usually when a switch inidicates a port up, it refreshes the mac table.

My analogy of synchronising of three phase alternators is not using " rotating batteries" as that does not make sense. I rather thnk of three flying members of the red arrows flying 120 digress with respect to each other performing a " barrel roll in one direction and following them are three flying members of the Blue angels, The idea of synchronizing the two teams is to get a passenger in each of the blue angles to jump over to the cockpits of the red arrows Without ANYONE GETTING HURT. Hence the required state is that the each team must be 120 digress with respect to each other and roling on the same diameter circle and in the same direction . Only then the equality of the voltage, the right phase sequence and the frequency are met, The rotating battery is a silly example to suggest as it is much more than that, The two , three member display team is a more faithful analogy. Perhaps rather than two display teams one should use three fuel tankers while three F-22 are all trying to refuel at the same time with the three tankers flying the equivalent of a three phase supply system, with the three F- 22 following with the required synchronised state! Hunting about the final point is interesting and excitation and throttle control is not explained by using " rotating batteries". One can use a similar demonstration using synchros or two wound rotor induction motors, If one excites the rotor with AC and rotate the rotor one can get a rotating three phase on the stator Two such motors excited from the same AC source can remain non rotating with a similar effect . Also the three light bulbs are not connected so that they all show zero voltage at synchronization but two will be bright and one will be dark. and they do show the difference in rotation and not only the pulsating effect, A synchroscope is only a unit with a three phase winding on the stator and a three phase winging on the rotor where the excitation from the two incoming alternators rotate the magnetic fields in different directions with the shaft of the unit remaining stationary at a particular direction when synchronization is best to be activated. ,

is there a way of braking a motor without spending electricity but instead generating it? I know, regenerating brakes, but how does one keep a constant rpm?

Your video and set up is amazing. May i know if I can get your set up circuit for me to follow it and assemble it as well? Thank you so much

Thank you

I have watched numerous videos about synchronizing generators but this is the only one i found that explains how they stay in synch! Wonderful job my friend, great demonstration and explination about this process. Thank you!

Hello, I invite BTCInstrumentation and Internet users to analyze my KZbin channel and website. Best regards 💖😀.

it is a very claer explanation. why 220 idiots didnt like it :D

Holy crap

I used to work in the Foxboro factory, for 2 summers. I never completely understood what the parts I made did! I find it interesting how you said that your unit had the wrong diaphragm. I worked in the capsule room, assembling and welding the diaphragms and flexures onto the capsules, then filling them with oil. Were you actually swapping out the entire capsule?

This made my day. One of the coolest demonstrations of AC I have seen 🙂

So I’m gonna go on a limb and say so the neons are connected phase to phase of each generator?

عجب جامع و عالی بود توضیحتون

"Probably the most complicated or confusing part is the torque tube itself..." Really?? Sure buddy.

Thank you, very well illustrated

by what process is a total NOx reading filtered to determine NO2 and NO3 levels?

Be careful, that cavitation you see just after the suction valve is caused by the pressure drop through the valve not the pump...sending them to the pump.

Excellent 👍

Isn't there a tool that do this automatically?

*Absolut GEIL! Danke für dieses Video.*

thank you

Waiting for the conspiracy idjits to chime in about how the gubberment is clearly hiding the infinite energy machines because you’ve got 2 running right there.

wireless intrinsically safe transmitter did need a zener or galvanic barrier in control room to limit the voltage and current . please can anyone answer me

If I have intrinsically safe wireless transmitter Ex ia did I need zener or galvanic barriers in control room

There used to be a tool making this easy to do. I have been looking for a set, but I guess they are no longer available.

Does the slave PLC not need any code for modbus? If I’m seeing send/receive instructions in a ladder program do I immediately know I’m reading a program meant for a master PLC?

13 years later and still helping thanks!
