14 ISOLATION VOLTAGE
Toverifytheintegrityoftheisolationatestvoltageisappliedforaspecifiedtimeacrossacomponentthatisdesignedto provide electrical isolation. This test is known as ’High Pot Test’, ’Flash Tested’, ’Withstand Voltage’, ’Proof Voltage’, ’DielectricWithstandVoltage’or’IsolationTestVoltage’. AllisolatedPowerModulesare100%productiontestedattheirstatedisolationvoltage. Thisis4kVDCfor1seconds. Theisolationtestvoltageindicatedinthisdatasheetisforvoltagetransientimmunityonly. Itdoesnotallowthisparttobe usedwithinasafetyisolationsystem. Themodulewillfunctionproperlywithseveralhundredsofvoltsappliedcontinuouslyacrosstheisolationbarrier,however surroundingcomponentsmustbeindividuallyanalyzedtoensureproperinsulation. Isolationmeasuresmustbetakeninto accounttopreventanyuser-accessiblecircuitryfromcausingharm.
14.1 Dielectric Test Setup (High Pot Test)
Connectallinputandoutputterminalstogether(seefigurebelow)beforeconnectingthesupplyvoltage. Whentesting,set thecut-offcurrentto1mAwithatestvoltageof4kVDCandtesttimeof1s. Module Figure2:Dielectrictestsetup.
14.2 Repeated High-Voltage Isolation Testing
Arepeatedhighvoltagetestofabarriercomponentdegradesitsisolationcapabilities. Theprimaryandsecondarywindingswithinthistransformerareenameled(coated)butdonotpossessadditionalisolation. Typically, parts can withstand multiples of their stated test voltage and still perform optimally. The magnet wire coating candegradeovertimeduetochemicalreactionsthatoccurathighvoltages. Werecommendkeepinghighvoltageisolation testing to a minimum to better protect the isolation between the windings. If repeated high voltage isolation testing is required,considerreducingthevoltagebyasignificantamounte.g. 20%fromthetestvoltagestatedwithinthedatasheet These safety concerns are equally applicable to components that utilize functional isolation beyond wire coating (i.e. physicalbarriersorspacing).
