As electric vehicles (EVs), renewable energy systems, and AI data centers continue to evolve, power electronics systems are rapidly moving toward higher voltage operation, higher power density, and faster switching speeds. These trends place increasingly strict requirements on insulation materials, insulation resistance measurement, and high-voltage testing methods.
Insulation resistance measurement is a fundamental technique for evaluating insulation performance and reliability. However, as measurement targets move into the ultra-high resistance range (10¹⁶ Ω and above) and test voltages exceed 1000 V, achieving reproducible insulation resistance measurements has become significantly more challenging.

Challenges in Insulation Resistance Measurement Reproducibility

In real-world testing environments, insulation resistance measurement results are often strongly influenced by:

• Measurement setup and wiring configuration
• Test fixtures and guarding techniques
• Environmental conditions such as temperature and humidity
• Grounding and noise interference
• Operator-dependent test procedures

Even small variations in these factors can cause large fluctuations in measured insulation resistance values. In many cases, engineers may not realize that measurement variability is caused by the test setup itself rather than the insulation material or device under test.
As a result, poor measurement reproducibility can lead to:

• Unreliable insulation material evaluation
• Inconsistent quality and reliability assessment
• Difficulty comparing results across different test conditions or laboratories
