Comprehensive Protection Scheme Testing with the Doble F6150

Testing protection schemes requires special electrical test equipment offering high power, sophisticated software and flexibility. The Doble F6150 Relay Testing System fits these specifications perfectly.  With a wide range of increasingly complex protection schemes, the Doble F6150 allows you to run comprehensive tests using just one test unit, alleviating the need to carry multiple tools in the field.

Diagnostic Capabilities of Doble M4000/M4100 are Unmatched

Doble M4000 M4100 Power Factor Insulation AnalyzerPoor 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.

Sweep Frequency Response Analysis Makes Transformer Maintenance Easy and Saves Time

Doble M5200 Sweep Frequency Response AnalyzerTransformers 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.

Doble M4110 Leakage Reactance Module

The M4110 Leakage Reactance Module from Doble Test Instruments

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.
