What is the dielectric effect?

Insulation property of a material

Why is water the enemy of insulation?

Water decreases the overall thermal performance of the insulation, also water may just short circuit around the insulation and render it useless.Water, if present on dielectric surface, due its high conductivity decreases the surface resistivity of the dielectric, thus causes high creepage current (surface current).

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.

What is insolation resistance?

I think you mean 'insulation resistance'. This is exactly what it says it is, it is the resistance between opposite sides of an insulator or dielectric. It is in the order of megohms and, in the case of a cable, is inversely proportional to its length -i.e. the longer the cable, the lower its insulation resistance.

Difference between insulation resistance and dielectric strength?

Insulation resistance measures the ability of a material to resist the flow of current through it, indicating how well it can prevent leakage. Dielectric strength, on the other hand, measures the maximum electric field that an insulating material can withstand without breaking down, indicating its ability to withstand high voltage before electrical breakdown occurs.

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.

What is difference between breakdown voltage and dielectric strength of transformer?

The dielectric strenght of a transformer represents the maximum voltage permissible to apply across the transformer insulation i.e. between the transformer winding to another part of the transformer, normally the chassis or another winding and without break-down of the insulation ocurring (e.g. arcing). The breakdown voltage of a transformer represents a voltage that exceeds its dielectric strenght and that causes breakdown e.g. arcing across the insulation.

What does dielectric strength mean?

Dielectric strength is the maximum electric field that a material can withstand without experiencing electrical breakdown. It is a measure of the insulation capability of the material. A higher dielectric strength indicates better insulation properties.

What is the basic insulation level of various electrical equipments?

BIL or basic impulse insulation level is the dielectric insulation gradient of a material tested to withstand the voltage stress at a voltage impressed between the material and a conductive surface beyond the BIL rating, an electric tracking starts to occur which will then result into an arcing flashover to the conductive surface. In addition it is the capacity of an equipment to withstand mechanical stress..like lightning strike without causing any damage to the equipment...
