What is the Difference between frequency converter and frequency inverter?
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid.

What is mean by load frequency control?
Power sharing between two areas occurs through these tie-lines. Load frequency control, as the name signifies, regulates the power flow between different areas while holding the frequency constant.
What is the frequency of the power waveform in capacitive circuit?
The frequency of the power waveform in a capacitive circuit, or for that matter, an inductive circuit, is the same as the input voltage or current. Its just that the current leads the voltage (capacitor) or lags the voltage (inductor) by a phase angle, the cosine of which is the power factor. It does not matter how many sine waves you have, or what their phase angle is; if they all have the same frequency, the resultant, by Fourier analysis, is still a sine wave of the same frequency.
What is the need of under frequency relay in load shedding on power system?
when the load on a certain system increases the frequency of the system falls normally. It is dangerous to operate the equipments when the frequency is lower than the normal rated frequency so shed the when the frequency falls under voltage relays are used. I hope i answered your question :)
How does A Frequency Converter circuit diagram look like?
Depends if you want to convert an RF signal to a different frequency, as all superheterodyne circuits do (most TVs and radios). That's called a frequency mixer. If you want to change a power line frequency to another, rectify it to DC, then chop with an inverter.
Why cut off frequency is called half power frequency?
Cut off frequency is that frequency at which the power output of the circuit reduces to half of its power in pass band. Power (P)= Current2 X Resistance. so to reduce the power by half we need to reduce the current by 1/sqrt{2} = 0.707 = 3 db. So it's also called half power frequency. http://enter4joy.com
What does a watt- hour measure?
A watt meter measures the electric power in watts from circuits. They can measure utility frequency, audio frequency power and radio frequency measurement.

What determines the frequency of an electromagnetic wave?
The frequency of the source that produced the wave.
what is a frequency converter?
A frequency converter is a power electronic device. It transforms Direct current to Alternating current of desired frequency and magnitude.

What is the Ripple frequency of full wave voltage doubler?
It's double the frequency of the power source.
What are harmonics in power distribution system?
Harmonics are a multiple of the fundamental frequency. If the power frequency is 60Hz, harmonics occur at 120Hz, 180Hz, 240Hz, etc.
What is instantaneous power factor?
Instantaneous power doesn't have a frequency; it's instantaneous!
Does the lower the AM frequency go require night power to be lower or higher?
Does the lower the AM radio frequency number goes require night power to be lower or higher?
What is relation in between power and frequency?
E=h(new) where new is like a frquency component so we can say power & frequency are directly praportion to each.
What is static frequency converter?
Static Frequency converter is a static device with power electronic component such as scrs etc
