Fundamentals of Electrical Safety Testing

Electrical safety testers, or “hipot” testers, are essential in electronics manufacturing. They apply high voltage to check dielectric withstand, insulation resistance, ground resistance, and bond integrity. Originally, hipot testers were simple step-up transformers, but modern versions use electronic sources to ensure accurate results. They comply with IEC-61010, which mandates maintaining test voltage for a specified duration. These advancements improve reliability, preventing voltage drops that could lead to incorrect safety assessments.
