Open secondary connections with power on the primary can lead to extremely hazardous Voltage potentials. CT options when purchasing include nominal range, opening diameter, split/solid core, output type (voltage/current), and output range (0.333VRMS, ±10V, 1ARMS, 5ARMS, etc.). CT vendors can...
However, people in the Northeast receive up to 1700 mrem per year, mostly due to radon that is natural to rocks and soil. Is 1700 mrem safe? Take a look at the sidebar to see. So what do you do if you're exposed? Find out on the next page. Radiation Exposure Dosage Chart: ...
For samples of solution heat treated and peak-aged states, we observe the formation of the nanocrystalline (Al,Mg)-rich oxide film and its transition to a detrimental (Zn,Cu)-rich layer from the surface to the interior. We find that the Mg content of the oxide layer decreases from 33...
If you've studied our article on transformers, you'll know that they're electromagnetic devices that change low-voltage AC to high-voltage AC, or vice-versa, using two coils of wire (called the primary and secondary) wound around a common iron core. In a mechanical inverter, either an ...
Reading the serial port. Find out about the optimal solution for reading data from COM port, follow simple steps to read and observe all serial port activity.
However, insulation can also keep things cold -- your refrigerator, for example, is insulated to keep the heat out. Either way, insulation saves energy by keeping your appliances from having to work as hard to maintain the temperature. This experiment helps you find out which materials make ...
and the shorter lengths through the socket channels. This can be a somewhat tricky operation, so be patient and work slowly in order to avoid kinking and binding as you run the cords. You may find a pair of needle-nose pliers helpful to grab the end of the wires as they become visible...
In a step-up transformer, we use more turns in the secondary than in the primary to get a bigger secondary voltage and a smaller secondary current.Considering both step-down and step-up transformers, you can see it's a general rule that the coil with the most turns has the highest ...
Burnt Hard Drive: The hard drive may burn due to heavy voltage and electrical storms in the PC or laptop. 2. How to Avoid Hard Drive Crash In order to avoid the situation of the crashed hard drive because of any above-mentioned reasons, you need to follow some tips while using the...
Locate the nameplates on a transformer associated with a power distribution system. Find the kilovolt-amperes rating, or "KVA," the secondary voltage, or "Vsecondary," and percentage impedance, or "Zpercent." As an example, assume the KVA is 1200 KVA, Vsecondary is 480 volts and Zpercent...
