Reduce motor downtime with sequential insulation resistance tests
Case Study: Insulation Resistance
How to perform pre-season checks on your chiller system
In the warm summer season, cooling equipment operates at near peak capacity. If that equipment is used for critical building functions, any equipment downtime for whatever reason is unacceptable.
Insulation tester vs megohmmeter
What is the difference between an insulation tester and a megohmmeter? Compare insulation meters, testers, megohmmeters, and meggers to learn about what's best for your needs.
What is an insulation multimeter?
The Fluke 15x7 Series Insulation Multimeter is a new category of test tool that combines a full featured True RMS DMM and a megohmmeter. It's an integrated tool for maintaining and troubleshooting motor systems, electrical distribution, and production equipment.
Insulation resistance testing capacitors and high-voltage components
Using a megger for insulation resistance testing capacitors and high voltage components.
How to choose the best insulation resistance tester
Examine six areas when deciding on the best insulation resistance tester for the application. Consider the equipment to be tested, test voltage requirements, the testing environment, other possible uses, the experience level.
Eliminate chicken scratch and start using your motor test data
Motor insulation testing of motor windings, baselining and data collection is an important step in preventive maintenance. Fluke insulation testing tools such as the Fluke 1587 FC Insulation Multimeter is an easy way to collect data and analyze trends.
5 Steps to Test Insulation Resistance in Failed Motors
Preventing motor failure problems will extend the operating life of system equipment. Insulation resistance testers can be used to determine the integrity of windings or cables in motors, transformers, switchgear, and electrical installations.
Using motor insulation resistance testing to prevent downtime
Preventing motor failure problems will extend the operating life of system equipment. Insulation resistance testers can be used to determine the integrity of windings or cables in motors, transformers, switchgear, and electrical installations.
Improve uptime by sharing insulation resistance test data
Being able to share test data among a team means more efficient preventive maintenance programs, broader system insight, and easier decision making.
Motor Dan's best practices: how to keep VFDs and motors running
Variable frequency drives (VFD) keep on gaining in popularity. Applied to blowers and pumps, they offer energy savings, and in mechanical applications they allow fine adjustments that wouldn't be possible by other methods.
Optimizing electric-motor efficiency - part II
In Part I of this short application note series, we discussed inspection points on motors to make during an energy audit or other efficiency program. Part I covers basic motor efficiency strategy and describes tests and cost savings for voltage and current unbalance and for power factor. Part II covers inspection points that are best incorporated into regular, long-term preventive maintenance.
Electrical transmission cables
Testing electrical cables (insulation resistance cable test, continuity, voltage) with the Fluke 1587 Insulation Multimeter at a Singapore electrical utility.
