The purpose of testing transformers is to test their electrical, mechanical and thermal suitability for the system in which they will be applied. Most tests of power transformers are covered in national standards such as IEEE NEMA and ANSI. This is because they have a uniform set to be recognized by the manufacturer and the user. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.
Transformer Test Details:
Field Testing. Field Testing can be broken down into three categories
Acceptance
Periodic tests
Failure testing
Acceptance tests should always be performed as soon as the product arrives at the destination. A few tests can also be done, as described below.
Turns ratio
Insulation resistance (Winding & core)
Power factor
Resistance (winding).
Relationship between phase & polarity
Oil tests (DGA, moisture, dielectrics, etc.)
Visual inspection
Periodic tests are conducted after the product’s permanent installation. This test is designed to detect potential problems early enough before they lead to failure. Here are some of them:
Ratio of Turns
Insulation resistance
Power factor
Resistance (winding).
Oil tests (DGA, moisture, dielectrics, etc.)
Excitation current testing
Visual inspection
It is possible to prevent unscheduled outages and even failure by following a regularly scheduled test schedule.
The following failure tests were performed on electric transformers
Ratio of Turns
Insulation resistance
Power factor
Resistance
Oil tests
Excitation current testing
Analysis of combustion gas/gas-in oil
Visual inspection (internal).
