Electrical Safety Production Testing on Power Supplies

摘要

One area of production safety testing that TDK-Lambda routinely gets inquiries on is the dielectric withstand test, sometimes known the as dielectric strength test or "hi-pot" test.rnHi-pot testing, derived from "high potential", ensures that good isolation exists between parts of the system. This helps guarantee the safety of the equipment and avoids operator injury or death by electric shock. Higher test voltages are used, then normally applied to the power supply; this is to simulate transient voltages on the input line, caused by lightning storms or electrical switching equipment.
