Скачать или смотреть AEMC® Quick Tip- Guard Leads: What are They?

It’s not a garbage lead… It’s not a ground lead… It’s a guard lead!
In this video, Gregg explains the purpose of the guard terminal on the AEMC® Model 6555 megohmmeter. You’ll see how to properly connect a guard lead during insulation resistance testing on a 3-phase dry type transformer, why it matters, and when to use it.

We’ll compare test results with and without the guard and show why this lead is essential for eliminating surface leakage currents and getting accurate, reliable readings.

Remember: Don’t throw the guard lead in the garbage- it’s the key to cleaner measurements and greater confidence in your test results.
