16. the hipot has to have the capability of supplying reactive and leakage current continuously This may require a current output that is actually much higher than is really required to monitor leakage current and in most cases is usually much higher than would be needed with DC testing This can present increased safety risks as operators are exposed to higher currents DC testing characteristics During DC hipot testing the item under test is charged The same test item capacitance that causes reactive current in AC testing results in initial charging current which exponentially drops to zero in DC testing DC testing advantages l Once the item under test is fully charged the only current flowing is true leakage current This allows a DC hipot tester to clearly display only the true leakage of the product under test The other advantage to DC testing is that since the charging current only needs to be applied momentarily the output power requirements of the DC hipot tester can typically be much less than what would be required in an AC tester to test the same product DC testing disadvantages 1 Unless the item being tested has virtually no capacitance it is necessary to raise the voltage gradually from zero to the full test voltage The more capacitive the item the more slowly the voltage must be raised This is important since most DC hipots have failure shut off circuitry which will indicate failure almost immediately if the total

50. load AC testing advantages 1 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 at AC voltages and 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 2 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 Slaughter INTRODUCTION sensitive to a sudden application of voltage the operator can immediately apply full voltage and read current without any wait time Another advantage of AC testing is that since AC voltage cannot charge a load there is no need to discharge the item under test after the test AC testing disadvantages 1 A key disadvantage of AC testing surfaces when testing capacitive products Again since AC cannot charge the item under test reactive current is constantly flowing In many cases the reactive component of the current can be much greater than the real component due to actual leakage This can make it very difficult to detect products that have excessively high leakage current Another disadvantage of AC testing is that
