In the industrial environment of Monterrey and its metropolitan area, where power quality and long-term reliability are decisive factors, dielectric strength (hipot) testing is an essential part of validation processes. However, in critical applications, verifying only that the insulation withstands a given voltage may not be enough to guarantee its performance in the field.
As part of a specialized service, partial discharge detection can be integrated directly during the hipot test, significantly raising the level of inspection without changing the test flow.
Greater depth in insulation evaluation
In a conventional hipot test, the main criterion is to verify that no dielectric breakdown occurs. However, there are internal defects—such as microvoids, inclusions, or cracks—that do not cause an immediate failure but do represent weak points.
Partial discharges (PD) are electrical manifestations localized at these defects. Although they do not produce a complete short circuit, they indicate a degradation process that can progress over time. Detecting them makes it possible to get ahead of failures before they become functional or safety problems.
Under guidelines such as those defined by IEC 61934, this type of measurement offers much greater sensitivity in insulation evaluation.
Integrating ARC detection during the hipot test
The service uses equipment with arc detection (ARC detection) functions as a complement to the high-voltage test. This technology identifies high-frequency signals associated with internal micro-discharges while the test voltage is applied.
In operational terms, this means a simultaneous evaluation:
- Hipot test: validates the insulation’s ability to withstand the specified voltage
- Partial discharge detection: identifies internal activity associated with incipient defects
This provides a more complete diagnosis without running additional separate tests.
Applications in regional industry
This approach is especially relevant in key sectors of northeastern Mexico, where reliability demands are high:
- Electronics manufacturing: PCB boards, control modules, sensors
- Automotive industry: harnesses, electronic modules, power components
- Electrical equipment: transformers, cables, insulators
- White goods and home appliances: systems with critical insulation
In all these cases, early detection of internal defects reduces the risk of field failures, returns, and warranty costs.
Service benefits
Adding partial discharge detection as a complement to the hipot test offers clear advantages:
- Deeper evaluation of insulation condition
- Identification of defects not visible in conventional tests
- Fewer latent failures in finished products
- Higher quality and reliability standards
- Direct integration into the existing test process
