Caution:If the master station connects directly to your home's electrical system, be sure to de-energize the circuit involved and take precautions to prevent someone else from turning it back on while you are working on the circuit. If a transformer is supplied with the master station to powe...
At this point in the measurement system, waveform data from the modules is used to calculate any power quality parameter desired. Some of these calculations are fairly simple while others are complex calculations aggregated over several cycles, seconds, or minutes to determine the ultimate quality. ...
Also, I used LiDAR measurement in the app to establish what size and type dish I had bought (a cheap no-brand thing in a store where immigrants buy satellite dishes to watch homeland TV) but later on Tije pointed out to me that the dish on the app screen looked nothing like mine whi...
-running directly off mains voltage is often hazardous unless you run it in conduit and shit. If you step it down first, you can have a bank of protection at your primary step down transformer thats heavy, and put lighter protection on your subsequent circuits. plus, a big surge would dam...
If your laptop has a charger you can no longer use, be sure to scrap that, too. The wire can be classified with your insulated wire, and if there is a small transformer on the end, you can cut that and throw it in your transformer pile. Once you have removed these items, the lapt...
By LearnMetering January 11, 2025 Current Transformer When working with current transformers (CTs) and potential transformers (PTs) in metering setups, calculating the burden accurately is critical to ensuring precise measurements. In this post, we’ll break down how to calculate burden, why it ...
There are five important things to do to make a good vertical stack. (1) Use identical antennas. (2) If you use coaxial cable, such as RG-59/U, you should also use a weather-proof 300-ohm to 75-ohm matching transformer mounted as close as possible to each antenna...
Any lines carrying signals into your home can also carry a power surge, due to lightning or a number of other factors. If you have a coaxial cable line hooked up to expensive equipment, consider a cable surge protector. Surges on these lines can do just as much damage as surges over ...
The easiest antenna with a good match is a dipole, but that is a bit more challenging to deploy in the field, so I opted for an end-fed halfway (or EFHW) antenna with a 49:1 transformer. I 3D printed a winder that allowed a BNC connector and the transformer to be mounted on the...
Repeat this process for the other lamp socket. Step 5 Bryan Trandem Join the socket cords to the lamp cord:At the center wire connection housing, join together the three neutral wires (the portion of the cord with faint ridges on the jacket) by twisting the bare ends together and screwing...
