What is HIPOT Testing (Dielectric Strength Test)?· Other examples include identifying a pinhole defect in insulation or finding an enlarged solder footprint. As per IEC 60950, The Basic test Voltage for Hipot test is the 2X (Operating Voltage) + 1000 V The reason for using 1000 V as part of the basic formula is that the insulation in any product can be subjected to normal day-to-day transient over voltages.
