| Insulation Resistance Testing
Insulation resistance testers should be an integral part of any comprehensive preventive/predictive maintenance program. You need to maximize the uptime of motors, cables and switchgear and Fluke MegOhmMeters can help you anticipate problems before they happen. Measurement storage and Fluke Quicklink PC interface software make it ideal for a proactive maintenance program.
Insulation Resistance testing can help to reduce the amount of diagnostic and troubleshooting time when there is a known failure and can also assist in maintenance planning and failure prediction of critical systems.
Common uses
- Installation test of motors and cables prior to start up.
- Quality verification of manufactured electrical devices.
- Ensure electrical devices meet codes and standards.
- Spot check of insulation resistance for troubleshooting of suspected problems in motors, cables and switchgear.
- Check for moisture ingress or contamination in motor windings and cables.
- Trending of insulation performance in motors, cables, and switchgear for preventative maintenance needs.
Application Reference – Tracking Electrical Problems
Checking leakage to ground along wiring paths is the only sure way to identify potential electrical problems. At the Minneapolis-St. Paul International Airport this is critical to keeping the runway lights and related systems lit and functioning. The airport maintenance department uses the Fluke 1520 MegOhmMeter to perform preventive maintenance, troubleshoot failures and locate trouble spots.
