TECHNICAL NOTES ISOLATION VOLTAGE REPEATED HIGH-VOLTAGE ISOLATION TESTING Hi Pot Test, Flash Tested, Withstand Voltage, Proof Voltage, Dielectric Withstand Voltage & Isola- It is well known that repeated high-voltage isolation testing of a barrier tion Test Voltage are all terms that relate to the same thing, a test voltage, applied for a speci ed time, component can actually degrade isolation capability, to a lesser or great- across a component designed to provide electrical isolation, to verify the integrity of that isolation. er degree depending on materials, construction and environment. While parts can be expected to withstand several times the stated test voltage, All products in this series are 100% production tested at their stated isolation voltage. the isolation capability does depend on the insulative materials used. A question commonly asked is, What is the continuous voltage that can be applied across the part in Such materials are susceptible to chemical degradation when subject normal operation to very high applied voltages. We therefore strongly advise against For a part holding no speci c agency approvals both input and output should normally be maintained repeated high voltage isolation testing, but if it is absolutely required, within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure that the voltage be reduced by 20% from speci ed test voltage. of immunity to transient voltages and the part should never be used as an element of a safety isolation This consideration equally applies to agency recognized parts rated for system. The part could be expected to function correctly with several hundred volts offset applied better than functional isolation where wire enamel insulation is always continuously across the isolation barrier but then the circuitry on both sides of the barrier must be supplemented by a further insulation system of physical spacing or regarded as operating at an unsafe voltage and further isolation/insulation systems must form a barrier barriers. between these circuits and any user-accessible circuitry according to safety standard requirements.
