A Hipot test (also called Dielectric Withstanding Voltage (DWV) test) verifies that the insulation of a product or component is sufficient to protect the operator from electrical shock. In a typical Hipot test, high voltage is applied between a product's current-carrying conductors and its metallic shielding.

Hipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. A hipot test checks for good isolation.

Hipot test makes surety of no current will flow from one point to another point.

Hipot test is the opposite of a continuity test.

Continuity Test checks surety of current flows easily from one point to another point while Hipot Test checks surety of current would not flow from one point to another point (and turn up the voltage really high just to make sure no current will flow).
The hipot test is a nondestructive test that determines the adequacy of electrical insulation for the normally occurring over voltage transient. This is a high-voltage test that is applied to all devices for a specific time in order to ensure that the insulation is not marginal.

Hipot tests are helpful in finding nicked or crushed insulation, stray wire strands or braided shielding, conductive or corrosive contaminants around the conductors, ter ...more

Many people are familiar with a continuity test. A continuity test checks for "good connections." You do a continuity test by seeing if current will flow from one point to another point. If current flows easily enough then the points are connected. Many people aren't familiar with a hipot test. "Hipot" is short for high potential (high voltage). A hipot test checks for "good isolation." You do a hipot test by making sure no current will flow from one point to another point. In some ways a hipot test is the opposite of a continuity test.

Continuity Test: "Make sure current flows easily from one point to another point."

Hipot Test: "Make sure current won't flow from one point to another point (and turn up the voltage really high just to make sure no current will flow)."

In the simple case a hipot test takes two conductors that should be isolated and applies a very high voltage between the conductors. The current that flows is watched carefully. Ideally not much current will flow ...more
