Insulation Resistance｜Glossary
This page is part of the Electrical Glossary for RF and coaxial systems.
What Is Insulation Resistance?
Insulation resistance is a measure of how well a material prevents electric current from flowing.
It indicates the ability of an insulating material to resist leakage current between conductive parts.
Higher insulation resistance means better insulation performance and less unwanted current flow.
In coaxial connectors, insulation resistance refers to the resistance between the inner conductor (center contact) and outer conductor (connector body), helping prevent signal leakage and electrical faults.
Insulation Resistance in RF and Coaxial Systems
In RF and coaxial systems, insulation resistance is critical for maintaining signal integrity and preventing leakage between conductors.
Low insulation resistance can result in signal leakage, noise, and reduced system performance.
Environmental factors such as humidity, temperature, contamination, and aging of materials can significantly affect insulation resistance.
At high frequencies, even small leakage currents can impact signal quality and system reliability.
Proper material selection, sealing, and environmental protection are essential to ensure stable insulation performance in RF systems.
