12. Insulation Tester – What? An insulation tester can be used to determine the integrity of windings or cables in: –Motors, transformers, switchgear, and electrical installations. Insulation testers measure the insulation’s ability to resist the escape of an electrical current –high resistance indicates little loss of current –low resistance indicates a significant amount of current is leaking somewhere along the insulation

13. Insulation Testing – Why? Human SAFETY !!! Liability

14. Insulation Testers – Why? Insure public and personal safety Eliminate the possibility of having a life-threatening short circuit or short to ground Testing the system against miswired and defective equipment: –it will insures a high quality installation –customer satisfaction –protects against fire or shock.
