Can you improve the voltage level without transformer?
yes, we can incease voltage level by aplifiers.......
What is meaning of water level sensor?
Level sensors are designed to detect the level of substances that flow. The idea behind a water level sensor is that it can detect the level of water in any given scenario.
What is the pt transformer?
The abbreviation, 'PT', stands for 'potential transformer' (in Britain, the abbreviation is 'VT', and stands for 'voltage transformer'). This, together with a 'current transformer', falls into a category of transformer known as 'instrument transformers'. A 'PT' or 'VT' is used to reduce a high voltage to a level of voltage that can be safely read, remotely, by regular a.c. voltmeters or to provide inputs to high-voltage protection relays, while electrically- isolating the secondary circuit from the high-voltage primary circuit for the purpose of safety.
What is the maximum touch voltage in dry conditions?
The maximum level of voltage allowed for a person to be exposed safely.
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.
Which of the following instruments can detect the presence of a voltage but not the voltage level a. clamp type meter b. wattmeter c. multitester d. neon circuit tester?
D. Neon circuit tester. Page # 59 in your book.
Can 120V appliance work with 220V?
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
What is an instrument transformer?
An 'instrument transformer' is a category of transformer used to supply measuring instruments or protective relays. There are two types of instrument transformer: a 'voltage transformer' (known as 'potential transformer' in North America), and a 'current transformer'. They are used with high-voltage systems, where it is hazardous to connect instruments directly to such systems.Voltage tranformers are used to reduce high-voltages down to a level that can be safely applied to voltmeters, or to the voltage-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instruments (and personnel) from the high-voltage supply.Current tranformersare used to reduce high-voltage currents down to a level that can be safely applied to ammeters, or to the current-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instrument (and personnel) from the high-voltage supply.
What is the purpose of voltage transformer?
A 'voltage transformer' (called a 'potential transformer' in North America) is classified as an 'instrument transformer', and is used to reduce the voltage of an electrical system to a lower, safe, level for the purposes of either operating a voltmeter or supplying a protection relay. At the same time, it electrically-isolates the meter or relay from the high-voltage system.
Can you improve the voltage level without transformer?
yes, we can incease voltage level by aplifiers.......
What is meaning of water level sensor?
Level sensors are designed to detect the level of substances that flow. The idea behind a water level sensor is that it can detect the level of water in any given scenario.
What is the Formula to covert voltage level to decibel?
You mean the conversion from voltage V to voltage level LV. Voltage level LV = 20 * log V 117 volts equals 41.36 dB. The reference voltage 1 volt means 0 dB.
What does PIR detect?
detect any changes in the environment (noise level, vibration, temperature)
How do you detect the charge level of rechargeable battery .. is there any special circuit to do that?
If you want to know the voltage of any battery you need a volt meter. These can be as cheap as 15- hundreds of dollars. Knowing the voltage still doesn't tell you if a rechargable battery is fully charged or not. a charger with an indicater can tell you that.
What is the calculation for the calibration of a Level instrument displacement type dry method?
How to find out the calculation for dry calibration of a level instrument used on the top of the tank? How to calibrate level instrument with the help of weights?
How does a decibel reader detect decibels?
A SPL meter is a sound pressure level meter where a microphone diaphragm is moved by the sound pressure variations and the voltage output of the microphone is shown at a voltmeter. The volts are calibrated to decibels.
Why ttl voltage level converting to rs232 level?
Whwn an IC is connected to a PC, then the voltage levels of these two should be synchronized. For this purpose, the TTL voltage level is converted to RS 232 level. RS 232 is the interface between a PC and an IC.
