The withstand voltage is the amount of electrical potential, measured in volts, which can safely be applied to an object in various environments, typically dry or damp or wet conditions, at normal atmospheric pressure and temperature.
The object must still remain functional after the voltage test has been completed.
This question refers to a test done in dry conditions.
The question also mentions power and frequency, which are attributes which refer to the type of electrical service being used to perform the test. The electrical service may be either alternating current, running at a certain frequency, or direct current.

What is power frequency withstand voltage?
Withstand Voltage : The voltage which has to be applied to a test object under specified conditions in a withstand test is called the withstand voltage ( as per IS:731 and IS: 2099-19631 ) unfortunately i don't know the name of the book, I just know " page 405 , chapter 10 , High-voltage testing of electrical apparatus " the book name is HIGH VOLTAGE ENGINEERING (2nd edition ) by Naidu, Kamaraju
What does No-load voltage mean?
A no load voltage means the power level that is giving from the output pins power converter. This is when 0% load is given.
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.
How do you reduce the Power dissipation?
Answer for mechanical systems:Use oil or grease to reduce friction!Answer for electrical systems:Making the voltage as high as possible is a good way to reduce power loss.ExplanationThe voltage drop along a conductor is proportional to the resistance and to the current carried. (V=IxR) So, for a given quantity of Power (W=VxI), if the voltage is made as high as possible there will be less current flowing and therefore less power loss.
What is inverter efficiency?
Inverter efficiency varies with DC input voltage, ambient temperature, and operating power level of the inverter. It can mean power-out divided by power-in.
What does BIL basic insulator level really mean and its differences with Impulse withstand voltage and power frequency withstand voltage?
BIL is basic insulation level as per you or in other words it would be "basic impulse level" which implies the limit up to which an insulator could withstand impulse due to lightning strikes. Impulse is generated on the insulation due to the high voltage surges and spikes due to lightning strikes. BIL is generally much higher as compared to power frequency withstand voltage. In other words BIL is lightning Impulse withstand voltage. Impulse withstand voltage is the voltage that is generated due to switching operation and it's much higher than power frequency withstand, but BIL or the lightning withstand voltage is a the voltage level that an insulation can withstand during surge or lightning strikes.

What is mean by power frequency withstand voltage and impulse withstand voltage?
Power frequency volatge is applied for a duration of one minute and as such there would be many cycles of sinusoidal wave form applied during the tets; hence, RMS value is considered. Whereas LI is a surge and is typically 1.20 micro sec. wave; hence peak is considered.
What is the power frequency voltage?
It's unclear whether you are asking about frequency or voltage. The frequency and voltage are specified in the relevant national standards, regulations, and legislation. In North America, for example, the residential nominal voltage is 240/120 V at 60 Hz. In Europe, the residential nominal voltage and frequency is 230 V at 50 Hz. By 'nominal', we mean 'named'. National regulations allow these values to vary within specified limits.
What does No-load voltage mean?
A no load voltage means the power level that is giving from the output pins power converter. This is when 0% load is given.
What do you mean by filtering output voltage?
power filter diagram
How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
What does bc in bc547 mean?
B for siliconC low power audio frequency
What do you mean by 3 dB cutoff frequency?
3db frequency is the frequency at which the value in the graph is reduced by 3db level It's also known as the half-power point.
Why does a low voltage circuit create more amperage than a high voltage circuit?
That depends on what you mean. If you mean why does a circuit which has a high voltage side and a low voltage side have a greater average current on the low voltage side, it is probably because of power conservation: P = IV. If this is not what you mean, you will have to be more specific!
The strength of an electrical signal is directly proportional to its frequency?
Hard to know what you mean by "strength". If you mean power, then the answer is no.
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.
