Pcb hi pot test
SpletThe test method is simple: apply a very high voltage potential (thus the name “hi-pot”) between the “hot” (L1, L2, etc.) & “neutral” (L0) wires and the main safety ground point and monitor the system for excessive current flow. A properly wired and insulated electrical system will have negligible current flow during this test. SpletIn electrical engineering, a dielectric withstand test (or pressure test, high potential or hipot test) is an electrical safety test performed on a component or product to determine the …

Splet30. apr. 2024 · Subsequent test steps halve the Rx value to double the current for each new test, e.g., 0.25 A, 0.5 A, 1 A, 2 A, 4 A, etc. Testing is terminated when the circuit opens. Testing remarks are that during the test the operation of a current or temperature limiter will stop the current flow and that current flow may start due to the operation of a GDT.
