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.

Transformers can sometimes experience significant physical stresses whenever they are moved from one location to another, such as when they are initially shipped from the manufacturer. Once they have been placed into service transformers can also experience tremendous stresses related to being in the path of fault currents when something goes wrong in the electrical system. The combination of mechanical and electrical stress can cause the transformer to prematurely fail. Symptoms may not be obvious until the damage is already extensive. Performing sweep frequency response tests can be used as an early identifier problems that occur as a result of physical changes within the transformer.

relay test set is generally heavy and large because it needs to produce large currents to be able to simulate the operating conditions of relays. It would be easier to test relays if you could move around without carrying the whole test system.

Leakage Reactance testing is highly sensitive to transformer winding deformation.  When these type changes occur, electrical losses increase and make the transformer less efficient. Additionally, these type indications, as reflected in the impedance of a transformer, can be used as a diagnostic tool to help maintain the health of the transformer and ensure its continued service.

Prevent the hassles of poor insulation with regular maintenance. Power factor testing is one of the common diagnostic methods used to evaluate the health of electrical insulation and to trend the degradation of that insulation over time.  Proper analysis of the data that is obtained in this type of testing is indicative of electrical losses within insulating materials and can be used to plan and prioritization of maintenance, repairs and replacement of electrical assets prior to failure.

For a reliable AC insulation analysis, rent the Doble M4000 M4100 Power Factor Insulation Analyzer from Protec today.
