Electrical safety is consistently one of the primary criteria evaluated before electrical or electronic equipment—or industrial components—are released to the market. A product may operate reliably yet still fail to meet requirements if its insulation lacks sufficient durability, its grounding resistance exceeds permissible limits, or leakage current occurs during operation.

When it comes to electrical safety testing equipment specifically Hipot testers—many QA/QC and testing engineers are familiar with the globally renowned brand Associated Research. A subsidiary of the parent company IKONIX, Associated Research (ARI) invented the world's first commercial Hipot tester.

Voltmeters are almost invariably found on the panels of electrical cabinets in factories, power stations, or generator systems. A glance lasting just a few seconds allows an operator to determine whether the power supply is stable or showing signs of abnormality. However, not everyone understands the significance of the displayed readings, particularly regarding three-phase electrical systems.

Few people realize that the concept of the "Hipot Test"—or electrical safety testing—has long existed within the electrical equipment manufacturing industry. Driven by the growing need to verify the voltage withstand capabilities of conductors, motors, and electrical devices, the industry required a robust and virtually fail-safe method to detect insulation weaknesses before products reached the market.
