Hi-Pot Dielectric Withstand Testing for Cable Assembly Safety Verification
As a specialized hi-pot testing provider, OurPCB delivers high potential dielectric withstand testing for wire harness and cable assembly insulation verification. Hi-pot testing applies controlled high voltage stress to verify insulation can safely withstand rated voltages with appropriate safety margins.
AC and DC hi-pot testing options accommodate different cable types and specifications. Test voltages up to 5000V AC and 6000V DC cover most medical device, aerospace, and industrial requirements. Insulation resistance (megger) testing provides megohm readings for detailed insulation quality assessment.
Safety agency compliance requires documented hi-pot testing. UL Listed products require dielectric withstand verification. Medical devices need patient safety testing per IEC 60601. Automotive high-voltage EV components require hi-pot verification for IATF 16949 compliance.
Leakage current measurement from 0.001mA to 100mA detects marginal insulation before failure. Programmable test sequences automate multi-step testing for production efficiency. Our quality systems ensure calibrated equipment and documented procedures per ISO 9001.
Hi-pot testing integrates with continuity testing for complete electrical verification. Test certification documents parameters and results for customer compliance records. Contact our testing team to discuss hi-pot and dielectric withstand testing for your cable assemblies.
Hi-Pot Testing FAQ
Hi-Pot (high potential) testing applies a high voltage stress to insulation to verify it can withstand its rated voltage with a safety margin. It detects insulation defects that could cause failure in service.
Hi-Pot testing is typically required for safety agency listings (UL, CSA), medical devices, aerospace applications, and any application where insulation failure could cause safety hazards. Many customer specifications require it.
Test voltage depends on the cable's rated voltage and applicable standards. Common test voltages range from 1000V to 3000V AC or DC. We set test parameters per customer specifications or applicable standards.
AC Hi-Pot stresses insulation with alternating voltage, detecting more types of defects. DC Hi-Pot is gentler on insulation and better for some materials. The choice depends on the cable type and specification requirements.
