high-pot tests send high voltages through a circuit to see if the circuit can possibly conduct to other branches. UL would use this to certify circuit safety
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
'Hi-pot' is short for 'high potential'. So, a 'hi-pot' test is a 'high-potential' test, and is used to test the insulation resistance of electricity-supply equipment, such as underground cables, etc. It does this by subjecting the insulation to a continuous (d.c.) over-voltage for a given period of time. The magnitude of the test voltage, and the duration of the test, is laid down by the standards that apply to the electrical components being tested.
'High-pot' is short for 'high potential', and it is also the trade name of a high-voltage test set used for testing the integrity of the insulation of high-voltage cables and other equipment prior to putting them into service, or following maintenance.
Hi-potting, also known as high potential testing, is a method used to test the insulation in electrical circuits by applying a high voltage to check for any leakage current. This test helps to ensure that the insulation can withstand the expected voltage levels and is key to preventing electrical breakdown.

High voltage cables with this high an insulation factor are usually given a Hi Pot (High Potential) test and not meggered. The potential has to be higher that the working voltage of the cable to be effective when checking for insulation or connector breakdown.
