Test probes for HV measuring device..?
Hi, Here's the thing. I bought a 10kV insulation tester a long time ago. It came with various cables. Today I discovered that not all test cables are approved for 10kV. The COM cable is only approved for 1kV, but it was originally supplied with the 10kV tester. Is that even allowed? I would say…
With a two-tariff meter, does the household electricity also run through the off-peak meter at night or ONLY the heating electricity?
To put it another way: A. Does a dual-tariff meter have two separate outlets for household electricity and heating electricity? And the off-peak meter, along with the heating electricity outlet, is only switched on at night. In that case, household electricity would also be "expensive at night" (= on peak tariffs). OR: B. Do household…
Measuring device does not fulfill all functions?
I received a measuring device for my exam, but the person responsible for it isn't here. No one else can help me. Hence the question: Can I measure protective conductor current with the Benning IT 120 B? Because Rlow is protective conductor resistance, Riso is insulation resistance, and what is protective conductor current?
How do I read the battery correctly with the measuring device?
Is it defective? (Pretty sure it is, but I still have some that work.) And what can you measure? And, of course, how to set up the measuring device. Thanks.
What form of technical connection do most smart meter gateways use to communicate with the electricity supplier/electricity meter operator?
According to 21390-technische-daten-smart-meter-gateway.indd (eonplus.de), for example, there are various types of external connections (towards the network operator). Which is used most often and why? What are the advantages and disadvantages of each connection? Does the "Ethernet connection" mentioned in the link use the internet connection provided by the customer? I'm grateful for any practical, technical…

Strange characteristic curve for PTC (thermistor)?
Could someone explain to me why the characteristic curve of the PTC looks so strange? From 100°C it makes sense, depending on the temperature R gets bigger, but why does the resistance get smaller up to 100°C? Thanks in advance for the explanation!
Measure voltage with a measuring device?
Hi, I have a question. I need to measure/test the light bulbs for our candle arch. How do I measure them, and what should I set them to without a measuring device (see image)? Can someone please help me? Thanks.
Which signal processing operations do I use here and what are the requirements for converting to discrete values?
Hello everyone, I'm currently practicing for the signal processing module in my mechanical engineering studies. I came across a problem here: "Suppose that for digital signal processing of an analog signal, you first want to represent the signal as a sequence of temporally equidistant values." First of all, "equidistant in time" should mean discrete. However,…
How is it chemically determined whether there is air in the gasoline-fuel mixture?
How can the air content (volume content…) be detected (chemically, petrochemically or physically)?
