A look at what insulation testing is all about…I’m doing as I prepare to do a tutorial on insulation testing and reviews on various insulation testers.
In this video I give a practical demonstration on how insulation testers can find possible short circuits…where normal multimeter continuity testers can’t do this.
In the future tutorial on insulation testing I’ll cover:
* What is insulation testing / How to do insulation testing?
* Spot or short time insulation / resistance readings
* Time resistance tests
* Step voltage tests
* Ramp voltage tests
* PI / polarization Index tests
* DAR / Dielectric absorption ratio tests
* Current absorption
I’ll be looking at insulation testers from Fluke (1587, 1507), Megger, Mastech (MS5203)
