What are the different uses of the acronym VFD?
VFD stands for the Volunteer Fire Department. Those who volunteer to fight fires are the bravest people, as they do it on top of their regular duties, and ask nothing in return.
Speed control of three phase induction motor by supply voltage control using AC voltage regulators?
No. Use standard utility AC, 3 PH voltage to feed a Variable Frequency Drive (VFD). The VFD is then wired to the motor. The output of the VFD varies average voltage and frequency in a semi-constant proportion to keep Volts/Hertz ratio the same to the motor. The operator can then adjust or select the desired speed from the VFD and the VFD will run the motor continuosly at that desired speed. If you were to control only voltage to the motor without adjusting frequency in proportion, the motor would burn up.
What would happened if you wired a 240v ballast and a 120 v ballast into a heavy duty timer?
The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
What are the different types of starter?
DOL, Star Delta, Soft starter, VFD
Can an electricition install a timer in the bathroom light?
A licensed electrician can install a timer on your light.
Did VFD exist?
Yes because VFD means Volunteer Fire Department and there are many characters in it
What to do to reduce the noise generated because of VFD or Motor?
To reduce the noise generated because of VFD harmonics, line filters have to be used on the line side and load side of the VFD. The specific filters suppress the harmonic frequencies that the VFD generates when the SCR's are rapidly turning off and on.
Is vfd real?
Yes
What brands of VFD's are you familiar with?
NO
Do you need a neutral wire to install a three way light timer?
If the wiring diagram calls for it,yes.
Where can I get a variable frequency drive?
There are several websites that offer Variable Frequency Drives, or VFD, for purchase on their website. Mitsubishi and AutomationDirect are two places that could be looked at for purchasing a VFD. Computers are not simple machines and thus require previous knowledge in order to upgrade or make repairs to, so you may want a professional to install the new drive for you.
Is count olaf in vfd?

What does lemony snicket have to do with vfd?
The VFD is real and it stands for. Volunteer Fire Department. At least that is what it says on Wikipedia!
Why vfd is used with fd fans?
Traditionally dampers are used to control the quantity of air entering the boiler. If we use VFD for FD fan, we can control the quantity of air be changing speed of fan using VFD. This will save energy.
