Because the cable has capacitance, and an AC source would not be able to distinguish between capacitance and leakage.
Yes, what matters is that the cable can take the correct voltage, and is thick enough to carry the required current, but ac or dc makes no difference.
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
The difference is the type of insulation on the conductors. Type AC used a thermoset insulation , Type ACT is a theromplactic insulation.
Capacitors are used in ac machines to assist the field during starting.
Are you planning to build a perpetual motion machine in which the power generated by an AC generator is used to run an AC motor which is used to run the same AC generator which provides it with power? Because that won't work. Yes, you can use a motor to generate electricity, and you can use electricity to run a motor, but the process is not 100% efficient and if you try to make it a closed loop, it will run down fairly quickly. So, what do we actually do? We use fuel to run an AC generator, or we use waterfalls or wind, or some other energy source, and then we use the power to run our motor.
You do not use AC to megger a device, because the purpose of meggering is to measure the insulation resistance of the device. You use DC to do that. If you used AC, you would be unable to differentiate between insulation leakage and capacitance.
No. The cable has capacitance, and an AC source would not be able to distinguish between capacitance and leakage.
Earth testing results should be related to the voltage source, i.e., AC in most situations. AC reacts to resistive and reactive loads, DC to resistive loads only. Not all earth testers, however, use AC.
megger are available in ac &dc
use a cable that is specified on the fan AC OR DC
Yes, what matters is that the cable can take the correct voltage, and is thick enough to carry the required current, but ac or dc makes no difference.
There are different types of megger, which is simply a trade name for a range of different instruments. Not all meggers use d.c., for example, an earth-resistance megger uses a.c. On the other hand, an insulation-resistance megger uses d.c. because it applies a constant test voltage across the insulation being tested.
ACT has thermoplastic insulated wires. AC is old MC is the modern cable.
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
...and DC? yes. The voltage rating may change, though.
Yes you can use the iPod Charger or any usb to ac
The maximum voltage rating for AC-90 armored cable is typically 600 volts. This type of cable is designed for use in various applications, including building wiring and power distribution, and is suitable for both indoor and outdoor installations. It's important to ensure that the cable is used in accordance with local electrical codes and standards.
