Voltage stress on an insulator refers to the amount of electrical stress or pressure that the insulator is subjected to due to the voltage applied across it. Excessive voltage stress can lead to insulation breakdown, resulting in electrical failures or arcing. Proper design and selection of insulators are important to ensure that they can withstand the voltage stress levels they are exposed to.

What is the purpose of skirts on a insulator?
Skirts on an insulator help to increase the leakage distance, providing better insulation performance. They help to prevent leakage currents and improve the overall efficiency and reliability of the insulator in high-voltage applications.
What is the stress word in electricity?
E
Why porcelain is a good insulator?
Porcelain is a good insulator due to its high dielectric strength, which means it can withstand high voltage without conducting electricity. Its structure also prevents the flow of electrical current, making it an excellent material for insulating purposes such as in electrical equipment and high-voltage applications.
What liquid is best insulator?
Silicone oil is often considered a good insulator for electrical applications due to its stability and high resistivity. It is commonly used in transformers and high-voltage equipment to prevent electrical leakage.
Is an LED an insulator or a conductor?
An LED (light-emitting diode) is a semiconductor device, which means it is neither a perfect insulator nor a perfect conductor. Semiconductors are materials with electrical conductivity between that of a conductor and an insulator. LED's conductivity can be controlled by applying a voltage, allowing them to both conduct and block electrical current.
What changes a voltage in a circuit?
an insulator
How can measure the voltage only seeing the insulators in a high voltage transmission lines?
i think 11kv per insulator
What benefit high voltage on ship?
smaller conductor,insulator & transformer
If voltage is not equal to current then are insulator rated in voltage or current?
Insulators are always rated for voltage. Voltage, or potential difference, is the energy that is available to make the electrons jump from the conductor, through the insulator, to the next available conductor. Current is the electron flow through the wire.A great example of why current is not an issue in insulation issues is that you could have 1000 amps (the measurement of current) going through a wire at 1 volt and have no problem with almost any insulator. You would need a very good insulator for less then a amp of current though if the voltage was 100,000 volts.
Break down voltage?
The breakdown voltage of an insulator is the minimum voltage that makes it partially conductive electrically. On the other hand, the breakdown voltage in a diode refers to the minimum reverse voltage to cause it to conduct in reverse.
Define methods of stress control in high voltage cables?
A method of stress control is controlling the distribution of dielectric stress. Uniform distribution of dielectric stress may be achieved in high voltage cables by surrounding the high stress areas of the high voltage cable with a tube of high permittivity material that makes contact at one end with a ground electrode contacting the shield of the high voltage cable.
Is a piece of paper insulator?
Yes, it helps hold heat in. But, if you are talking about electricity it doesn't at low voltage but at high voltage it will start to conduct.
Does parcel tape insulator electricity?
Most parcel take is made from polypropylene, which is indeed an insulator. However, it is not suitable for insulating high-voltage or household wiring.

What is a good electical insulator?
Depends on the voltage but, fiberglass, rubber and ceramics are common in the electrical industry.
