Doble M4000 M4100 Power Factor Insulation Analyzer

Poor insulation can cause serious problems in electrical power distribution. Testing and maintenance programs that include power factor testing of electrical distribution equipment helps to identify potential problems early and to monitor the progression of those problems.  Power Factor testing is an AC insulation test that would be applicable on many types of electrical insulation including the insulating component of cables, motors, generators, transformers, circuit breakers and other power system apparatus.  This type of measurement accommodates planning of maintenance, repairs and replacement of power system components without compromising the electrical system.

The Doble M4000 M4100 Power Factor Insulation Analyzer is capable of testing most electrical insulation in an industrial setting. The Doble M4000 M4100 can measure tan delta or power factor, directly and at 10 kV equivalent values.  Additionally, this test equipment is capable of performing no load excitation current tests on transformers as well as provide AC loss indicators for a variety of other electrical apparatus. Using a Line Frequency Modulation System, the impacts of high interference environments can be effectively minimized. The Doble M4000 M4100 can be used with the type C resonating inductor to extend its range of testing capabilities when performing tests on highly capacitive specimens such as motors and generators.  Other options are available for performing short circuit impedance tests on transformers  The Doble M4000 M4100 also can generate its own well-defined sine wave signal to ensure high accuracy testing. 

Diagnostic capabilities of the Doble M4000 M4100 system:

• Power Factor Testing to confirm insulation integrity and quality

  • Capacitance Testing to measure physical changes that may have occurred to the apparatus
  • Turns Ratio Testing to detect shorted turns or winding damage
  • Leakage Reactance/Short Circuit Impedance Testing to evaluate winding deformation
  • Single Phase Excitation Current Testing to evaluate the transformer magnetizing circuit
