Electrical Safety Tester – What?
•Universal instrument for testing the electrical safety
of portable electrical equipment in commercial and
medical applications.
•When evaluating electrical safety, tests are performed
for:
– protective conductor connections
– insulation resistance

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