Developments in Hipot Testers
The hipot test—also known as flash, high-voltage, or dielectric strength test—is one of the more controversial electrical safety tests and has provoked much discussion and debate. In fact, hipot testing is not a measurement, but rather a procedure that aims to illustrate whether a product remains safe when subjected to high voltage and whether the [...]
What is a Hipot Test?
Many people don’t know what Hipot Testing is so I’ll briefly explain it.
Most people know what a continuity test is. A continuity test checks for good connections. Continuity tests are done by seeing if currents flow from point to point. If the currents flows easily the points are connected. “Hipot” is short for high [...]
Hipot Testing Criteria IEC 61646 10.3
10.3 Insulation test
10.3.1 Purpose
To determine whether or not the module is sufficiently well insulated between current carrying parts and the frame or the outside world.
10.3.2 Apparatus
a) A d.c. voltage source, with current limitation, capable of applying 500 V or 1 000 V plus twice the maximum system voltage of the module (as marked on [...]
