Service description
We perform dielectric strength (HIPOT) testing under controlled conditions, applying high voltage to verify the integrity of electrical insulation in equipment, cables, and assemblies.
The service includes arc event (ARC) detection, making it possible to identify incipient faults that are not visible through leakage current measurement alone.
What is evaluated?
- Insulation withstand at high voltage
- Leakage current (mA)
- Presence of incipient partial discharges (ARC)
- Defects such as:
- Surface contamination
- Moisture
- Microcracks in dielectrics
- Inadequate insulation clearances
Typical applications
- Power and control cables
- Automotive wiring harnesses
- Industrial electrical equipment
- Panels and enclosures
- Electric motors (low and medium voltage)
- Electronic equipment with safety requirements
Technical methodology
- Pre-test inspection of the DUT
- Voltage setup per applicable standard
- Application of controlled voltage (AC/DC)
- Monitoring of:
- Leakage current
- ARC events (incipient discharges)
- PASS / FAIL evaluation
- Recording of results
Deliverables
- Detailed technical report
- Test parameters (V, mA, time)
- Evidence of compliance
- Technical observations
- Log of anomalous events
Reference standards
- NOM-001-SEDE (Mexican electrical installations standard)
- NOM-019-STPS
- UL / IEC (depending on the customer’s application)
- Applicable electrical safety tests
Added value
- Fault detection before catastrophic failure
- Less rework in production
- Fast validation on the line or in the laboratory
- Specialized technical support
Coverage
Service available in Monterrey and the metropolitan area
(On-site or in-laboratory option)
