Routine tests ensure the reliability and safety of transformers, circuit breakers, CTs, and switchgear in electrical systems.

• Transformer tests include insulation resistance testing and power factor testing.

• Circuit breaker tests involve functional testing and timing analysis.

• Current transformers (CT) are tested for ratio accuracy and burden testing.

• Switchgear is subjected to dielectric testing and contact resistance mea...read more

Current Transformers (CT) and Potential Transformers (PT) are selected based on parameters like accuracy, burden, and insulation level.

• Accuracy Class: CTs and PTs are rated for accuracy, such as 0.1 or 0.2 for CTs, which determines their performance in metering applications.

• Burden: The burden is the load connected to the secondary side of the transformer, affecting its performance; for example, a CT with a 5A output ma...read more

Explanation of tan delta test and winding test in transformers

• Tan delta test measures the insulation quality of transformer windings

• It is performed to detect any insulation defects or aging in the transformer

• The value of tan delta should be low, ideally less than 0.5%

• Winding test is performed to check the integrity of transformer windings

• It helps to detect any short circuits or open circuits in the winding

• Manufactured ...read more
