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.

When ground fault or microprocessor relay testing is needed, there’s no better relay test set than the Doble F6150 Relay Testing System. This high tech solution to diagnostic simulation testing offers all the powerful flexibility that is vital to protective testing and keeps electrical equipment running optimally.
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.

A 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.
