What else can I help you with?
How does the moisture and temp effect the breakdown strength solid dielectric?
Generally, increased moisture levels will lower breakdown strength, especially if the dielectric readily absorbs water. Increasing temperature generally decreases breakdown strength of solid dielectrics. The dielectric strength of some materials may increase with temperature within limited temperature ranges. However, dielectric strength eventually begins to decrease at higher temperatures.
What is the speed of light in vacuum divided by the speed of light in medium?
The speed of light in a vacuum is 186,000 miles per second and the speed of sound at 70 degrees F at sea level is approx. 1100 feet per second. Do the math. You should come up with something around 879 thousand. (a ratio, with no units)
Why is ceramic a good insulator?
No electron support, there by giving it a very high dielectric strength.
Why water is not used as a dielectric medium?
Water is a fine dielectric. One of the main issues is that it ionizes certain materials. If it comes in contact with metals, some ions may be leached into the water. This thus raises the conductivity of the water. Good dielectrics are bad conductors. This helps the capacitor store more charge. If the water becomes conductive, it fails as a good dielectric.
Vaccum or vacuum?
It is vacuum
For an insulating material dielectric strength and dielectric loss should be respectively?
For an insulating material dielectric strength and dielectric loss should be respectively
What is the effect of inserting a dielectric other than air vacuum between the plates of a capacitor?
Inserting a dielectric other than air or vacuum between the plates of a capacitor increases the capacitance of the capacitor. The dielectric material increases the electric field strength within the capacitor, which enhances its ability to store charge. This results in a higher capacitance value compared to having air or vacuum between the plates.
For an insulating material dielectric strength and dielectric loss should be what?
high and high
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What is dielectric breakdown?
The dielectric breakdown strength is 3,000 volts per millimeter.
What is the dielectric breakdown strength?
The dielectric breakdown strength is the maximum electric field that a dielectric material can withstand before it breaks down and allows electrical current to flow through it. It is a measure of the insulation properties of the material.
Which is another name for dielectric strength test?
ASTM D149 - 09 Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies
How can you test the dielectric strength of oil of transformer?
dielectric strength is tested by transformer dielectric strength oil testing machine. at first, oil which is to be tested is pour near the two electrode. both the electrode should be dipped in oil . then adjust the distance between the electrode .now start the machine.when a sound came from machine then note down the dielectric strength of the oil.
For an insulating material dielectric strength and dielectric loss should be respectively high or low?
For an insulating material, the dielectric strength should be high to withstand high voltages without breaking down. Conversely, the dielectric loss should be low to minimize energy loss due to internal friction within the material when subjected to an electric field.
How does the moisture and temp effect the breakdown strength solid dielectric?
Generally, increased moisture levels will lower breakdown strength, especially if the dielectric readily absorbs water. Increasing temperature generally decreases breakdown strength of solid dielectrics. The dielectric strength of some materials may increase with temperature within limited temperature ranges. However, dielectric strength eventually begins to decrease at higher temperatures.
Where is the knowledge of dielectric strength helpful?
One field in which this is helpful is in the manufacture of insulating materials. Dielectric strength determines the strongest electric field an insulator can withstand before it fails. For example, if the insulation around a wire melts or breaks, the insulator's dielectric strength is compromised.
Which is the best electrical insulator?
According to a few charts I was able to find, the most realistic material with the highest dielectric strength happens to be Mica, with dielectric strength of 118.
