tan delta test means we test the healthiness dielectric strength of bushing present condition,at this same time we maser capacitance also .
conductor surrounding oil impregnated paper is there it is terminated at test point,it is equivalent to capacitance .Healthy capacitor current and by 90 degrees.during deterioration time some resistance added,resultant is leakage current,it is checked by we conducting tan delta.
this resultant values compared to manufacturer reports and factory test reports.
tan delta value always in percentage.
Allowable value for tan delta test is 0.8 %
tan delta also called loss angle.
test details : we are using megger kit,it is combination of control unit and transformer unit.
we are applying 2kv 5kv 10kv
our kit capacity is 12kv. you have one dought here ,Wye we are applying higher voltages for higher Transformers bushings,
you remember one thing here we increase voltage ,will not increase
loss factor (tan delta)

What is preliminary test for blood?
A preliminary test for blood typically refers to initial screening tests conducted to assess various components of blood, such as complete blood count (CBC), blood typing, or basic metabolic panels. These tests help identify abnormalities in red and white blood cells, platelets, and electrolyte levels, providing crucial information for diagnosing medical conditions. Preliminary tests are often performed before more specific or detailed tests are conducted.
What type of tests are done on paperboard?
Tests conducted on paperboard include mechanical tests such as tensile strength, burst strength, and tear resistance to evaluate its durability and performance under stress. Additionally, physical tests assess properties like thickness, density, and moisture content, while optical tests measure brightness and color consistency. Chemical tests may also be performed to determine the presence of additives or contaminants. These tests ensure that the paperboard meets industry standards for various applications.
Difference between presumptve and confirmatory tests?
Presumptive tests are initial screening tests used to suggest the presence of a substance, such as drugs or biological materials, based on observable reactions or indicators. They are generally quick, cost-effective, and can yield results without extensive analysis. Confirmatory tests, on the other hand, are more specific and definitive, providing conclusive evidence of the presence and identity of a substance through advanced techniques like chromatography or mass spectrometry. Confirmatory tests are typically conducted after a presumptive test has indicated a positive result.
Do you have to fast for estrodial test?
Typically, fasting is not required for an estradiol test. However, it's essential to follow your healthcare provider's specific instructions, as they may recommend fasting based on your individual circumstances or other tests being conducted. Always consult with your doctor for the best advice regarding preparation for any lab tests.
How many type of soil tests in roads and bridges?
There are several types of soil tests commonly conducted for roads and bridges, including Atterberg limits, compaction tests, shear strength tests, and density tests. Additionally, geotechnical investigations may involve more specialized tests like cone penetration tests (CPT) and standard penetration tests (SPT). These tests help assess soil properties, stability, and suitability for construction. The specific tests chosen depend on project requirements and soil conditions.

What are the different tests conducted on cables?
Various tests are conducted on cables to ensure their performance and safety, including insulation resistance tests, which measure the integrity of the insulation; continuity tests, which check for proper electrical connections; and dielectric strength tests, which assess the cable's ability to withstand high voltages. Other tests include temperature rise tests, to evaluate heat dissipation under load, and mechanical tests, such as tensile and bend tests, to determine the cable's durability. Additionally, flame retardancy tests may be performed to evaluate the cable's resistance to fire.
