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 one minute withstand power frequency voltage for 11 KV vacuum circuit breaker?
it means the rms value of 11 kv that vacuum C.B. can withstand it during 1 minute
What is the Ripple frequency of full wave voltage doubler?
It's double the frequency of the power source.
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.
How do you figure out an appliance's power consumption if you have the voltage and Frequency and Current?
You just need the voltage and the current. Watts = Amps x Volts.
What is power frequency withstand voltage test?
A test done on a transformer. The voltage at the power frequency is ramped up to verify the transformer is capable of handling the stresses due to switching and natural phenomena (lighting strikes).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".

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 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 one minute withstand power frequency voltage for 11 KV vacuum circuit breaker?
it means the rms value of 11 kv that vacuum C.B. can withstand it during 1 minute
What is the Ripple frequency of full wave voltage doubler?
It's double the frequency of the power source.
What does power frequency withstand voltage test dry mean?
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 i s power frequency voltage?
Power: energy transferred per unit time.In electrical circuits, in the simplest case power is voltage x current (in AC circuit, you also need to multiply by a so-called "power factor", which is often close to 1).Frequency: the number of cycles per second.Voltage: energy required per unit charge, when moving a charge between two points. Thus, the voltage is always expressed (or at least implied) as a VOLTAGE DIFFERENCE between two points.
Save power by lowering the CPU frequency and voltage?
P states
What are the voltage requirements for power outlets in India?
The voltage requirements for power outlets in India are typically 230 volts at a frequency of 50 hertz.

What does the power intverter in a power supply do?
The primary function of the power inverter in a power supply is to change the direct current (DC) to the alternating current (AC). The design of the power inverter is dependent on the input voltage, output voltage and frequency, meaning that the inverter could be solely electronic or may have a combination of electronic circuits and mechanical effects.
