VFD- variable frequency drive, is a power electronics device which control the motor speed. It is very famous in Industries for energy saving perpose.
What is
Possibly a solar energy panel could be considered as having the same function as a chloroplast, in that it captures light energy and converts it into mechanical or chemical energy.
One application of feed back control is where the speed of a motor has to be maintained at a certain RPM and the load it drives is variable. Feedback from the load tells the VFD (Variable Frequency Drive) motor controller what to do. As the load drags the motor speed down the feedback unit sends a electrical impulse to the VFD to increases the speed of the motor. As the load drops off the feedback unit sends a electrical impulse to the VFD to decreases the speed of the motor. These interactions keep the motor RPM at a constant speed. This is a very simplified version of what happens.
Frames panel changed it's name to States panel.
h.t panel is a high tension panel from that all machineries get supply through u.gcables
Vfd is used for maintaing the pressure of whole chiller line.
What is
Yes because VFD means Volunteer Fire Department and there are many characters in it
You can either use the inbuild timer in VFD or go with secondary timer or a controller like PLC. You may use the below link to learn more on VFD www-dot-smeclabs-dot-com
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.

The VFD is real and it stands for. Volunteer Fire Department. At least that is what it says on Wikipedia!
