I initially thought about making a sensor like this, but as a level transmitter for my arduino. I planned on using a 555 in a monostable configuration in order to read its actual capacitance value. Then after would have to calibrate it in order to correlate its level to its reading. [Edit] I shared your video to GreatScott. He had a project recently to monitor a water tank level and used an ultrasound sensor in the end. But I wanted him to be aware of your creation :)

In the first version it may be intersting to change the BC337 for an opamp led drive. The leds goes in the feedback loop of one non inverting opamp. With this configuration the leds turns on gradually from zero.

the reason you have to turn down your inverter is because it has to sync to the sine wave on the grid and with grid down it has no way to sync

16:40 - I think you came up with quite an elegant solution for the problem. It would greatly reduce the possible errors in the flat surface and the results would be more than suitable for a lathe or similar project.

I wonder what to do in the situation faced by me? The two Neutrals from the two outputs 230 VAC of the Nitrox Inverter ( 3 KW - 24 V, SP - Hybrid _ by A.P.T. ) aren't allowed to be jointed! At my home the PE and the Neutral are NOT jointed! Neither the Solar Panels nor the Inverter is Grounded till now! The Inverter demands the two Neutrals to be isolated and afloat! I'm rather perplexed. Obviously the two Phases are certainly to be distributed isolated! The problem faced has been that either regular Load RCD or the Smart Load RCD have been in the habit of tripping off upon Grid On / Off since installation. Even sometimes the RCD on the Input to the Inverter also goes off! The reason: the wiring of my home has become leaky for sometimes. I've been curious about the Phase difference of the two outputs of the Inverter. Is there any way to examine it's two lines 230 VAC (RMS) each. Probably phase difference of 120° with about 460 VAC (RMS) that amounts to be ~ 651 VAC RMS, oh no, sorry I mean to say 650 VAC Peak ! Moreover, the grounding croc clips of the O-Scope share the same common ground! Is there any way to compare the 2 outputs, one 'Regular Load' and the other 'Smart Load' be visualized on single O-Scope screen with custom devised High Voltage Probe(s) X100 on single or Dual Channel OScope? Note: The Inverter trips the RCD's on bringing the the neutrals near each other. I've a plan to examine the phase relationship of the Regular and the Smart Output phases without putting any load on these. The OScope to be used is a Rechargable Battery Operated ( Floating ) DSO ’ZEEVEII DSO3D12’ I've seen your kind vlog on a ’DP’ Passive Differential Probe utilizing Dual Channels on an Oscilloscope for measuring High Voltage safely, safe for the Operator, the OScope and the Device Under Test DUT. Would you suggest me to use similar probe for the situation faced by me. I'm waiting for 2 Accessory DP4100 Probes X100. With afloat DSO, the Cric Clips of the 2 DP4100 X100 grounded to earth and the probes on the two phases? Wouldn't it be safe for me , the OScope and the electrical system? Awaiting your kind response!

You *must* have a single ground. I mean a grounded spike to which all grounding convey, including the PE line. Power the oscilloscope referencing to that ground. Then use a couple of active differential probes rated at not less than 1000V. The measurement must be performed knowing the procedures of how to handle high voltages and you must know what you're gonna do because this could be lethal! I won't take liabilities. On the oscilloscope use math functions to know the difference between the two AC sources. You mention 460V RMS and ~651V RMS ...I don't think this is correct starting from 230VAC RMS, I'm afraid you keep confusing RMS with peak and peak to peak. Oscilloscopes *always* display peak to peak voltages. For voltages out of phase you can't really use the root square of 2 to go back and forth RMS. About the problem you face with that inverter I have a similar issue with a hybrid solar inverter, made by Voltronic, China. I have had no chance to investigate the problem deeply enough but it seems the problem arises from the fact that the inverter must disconnect neutral from ground when running over the grid, and reconnect it to ground when running over solar panels and batteries (UPS mode). What you describe, two separate neutrals, seems quite weird but for those inverter designed to run on two phases grids (no neutral) that are in use in some corners of the world. It seems an interesting case.

9:42 I suppose at this point you meant 230uA rather than 320uA? O.K.? What are the safely full scale voltage measured by O-Scope with X1 and X10? Are these 3.2 and 32 VDC or RMS? 990 KOhm is almost 1000 KOhm or 100 MOhm to constitute a Probe 100X while in unison with standard 10X one. In my humble opinion, wouldn't have it been better if the Standard Probe used in X1 confuguaration for safety of the O-Scope? And all calculation done on the later basis? Help me if I'm confused. I'm a medical doctor happened to be an accidental scientist: may be on wrong side! I've never used any O-scope other than patient bedside monitors. My first ever entry level Chinese Rechargable, Dual Ch, SigGen O-Scope+DMM (ZEEVEII-3D12) with Voice-Assistant reached me 2-3 days ago. In search of safe use of the same I touched your KZbin channel. In my life, I've been moved by a few, and you are one among those, I happily ❤️ declare. Help me please if I'm confused or wrong! Thank you.

First off thanks for commenting. Indeed your comment could be of help for others. It could be helpful because many could confuse some points that clearly I have taken for granted when they'd not ...that's the curse of people with experience :) The current value is correct: around 320uA @ 230VAC. So why it is correct? An oscilloscope do not take the RMS voltage but the peak(+DC) voltage, while it shows the peak to peak voltage. I know, this may arise even more confusion, but don't worry, follow me. Let's take a sine wave that you want to measure at the oscilloscope. The instrument will show the sine wave from a reference point that is the GND (ground) level. In respect to GND the alternate sinusoidal signal swings from zero to full positive; then back to zero (GND); then down to full negative and finally back to zero again, where the cycle start over again. So what you actually see on screen is a wave that swings from peak to peak. However what matters for the input circuit is the voltage peak as an absolute value, which is the maximum allowed voltage in respect to ground irrespective of the polarity. Indeed if we look at the specifications of an oscilloscope they tell us the maximum input voltage that is meant as peak+DC voltage. In other words it is the absolute maximum voltage, be it AC or DC. So speaking about a possible voltage to measure I took as a reference example 230VAC, the mains voltage in EU. Mains voltage is alwasy declared as RMS voltage. So, for a sine wave with a 230 RMS voltage, for the purpose of finding the voltage that the oscilloscope's input matter we need to find out the peak voltage. Which for such a sine wave is: 230 times the square root of two, or simply 230 * 1.41 = 324.3 Vpk. When we compute the current across a resistor usually we compute it as DC or peak value, rarely as RMS value. And since we want to know the voltage at the input of the oscilloscope we have to calculate the peak value. So the math is as follow: Input voltage 324 Vpk / (990Kohm + 10Kohm) = 324uA. Remember, the current flows through both resistors to GND. Now because we know the current, and because the same current flows on both resistors, we can compute the voltage across the 10K resistor: 324uA * 10K = 3.24Vpk. Notice we should also consider the input impedance of the oscilloscope which happens to be in parallel with the 10K resistor. Though since this impedance is about 1Mohm at DC (or at very low frequencies such as 50 or 60 Hz) it doesn't change much our computations: 1/ ((1/1M) + (1/10K)) = 9900 ohm, actually an added attenuation of 1% . The probe x1 change anything as it is just a chunk of wire. Now, about the safe usage of the instrument, understanding that you are not that experienced, I'd recommend you to avoid taking measurements from mains. Instead use it to make measurements of small voltages of devices fully insulated from mains. In such a case it is quite safe to use in any condition. I never heard of that brand/model of oscilloscope, BTW. Hope this will be helpful. P.s. Thanks for love. Love+Peace.

@@AccidentalScience I got your point! For all practical purposes, regarding AC voltage or current we talk about it's effective value, the root mean square RMS value that is equivalent to its counterpart DC's heating effect. It's the peak value of the AC V or C 'times' the Inverse of Square Root of 2 = 0.7071 In true measurement one has to consider the Peak Voltage or Current of the AC that's RMS value times √2=1.4142. So it would be around 325 uA. This has to be accommodated resistance and capacitance calculation. I'm grateful for reminding me!
