"Risks of Over-Specifying Test Requirements: Testing Shielded Cables at High Voltage"
Testing electrical cables at high voltage helps to identify the presence of moisture, solder flux, or contamination — that may have penetrated breaks in the insulation or connector backshells, and ensures that the insulation between wires can sustain temporary voltage excursions higher than the normal operating voltage without breakdown.
The result of a high voltage test typically shows the insulation resistance between wires in the hundreds of megohms or higher. Test specifications requiring insulation resistance of 5 GΩ are not uncommon.
As test equipment suppliers, we frequently hear from our customers who are burdened with over-specified test requirements imposed by their customers. We show that it is not necessary to apply voltage to the shield conductors to accurately test insulation resistance as long as the shields remain at zero volts when the other wires are tested at high voltage. Additionally, we show that specifying testing at higher and higher voltages is neither necessary nor safe to the operator or product, even with technology that has been on the market for many years.
Target Audience: Those who manage test specification generation or manage/perform testing.
