12. contact our CUSTOMER SUPPORT GROUP at 1 800 858 TEST 8378 Many safety agency specifications allow either AC or DC voltages to be used during the hipot test When this is the case the manufacturer must make the decision on which type of voltage to utilize In order to do this it is important to understand the advantages and the disadvantages of both AC and DC testing AC testing characteristics Most items that are hipot tested have some amount of distributed capacitance An AC voltage cannot charge this capacitance so it continually reads the reactive current that flows when AC is applied to a capacitive load Qu AC testing advantages AC testing is generally much more accepted by safety agencies than DC testing The main reason for this is that most items being hipot tested will operate on AC voltages AC hipot testing offers the advantage of stressing the insulation alternately in both polarities which more closely simulates stresses the product will see in real use Since AC testing cannot charge a capacitive load the current reading remains consistent from initial application of the voltage to the end of the test Therefore there is no need to gradually bring up the voltage since there is no stabilization required to monitor the current reading This means that unless the product is sensitive to a sudden application of voltage the operator can immediately apply full voltage and read current without any wait time Another advantag
