To test transformers, it is necessary to determine whether they are suitable for use or application in an electrical, thermal, and mechanical system. Many of the tests on power transformers are described in the IEEE, NEMA, ANSI national standards. Their purpose is to create a uniform set for both the manufacturer as well as 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. There are three types of field testing.

Acceptance

Periodic tests

After failure, tests

Acceptance testing should be done immediately after the product arrives at destination. These are just a few of the tests that can be performed.

Ratio of Turns

Insulation resistance (Winding core and insulation)

Power factor

Resistance (winding).

Relationship of phase and polarity

Oil tests (DGA, moisture, dielectrics, etc.)

Visual inspection

Periodic testing is done after the product has been installed in its permanent place. This is done to check the condition of the unit and detect any possible problems before they cause a problem. Below are some examples:

Turns ratio

Insulation resistance

Power factor

Resistance (winding).

Oil tests (DGA, moisture, dielectrics, etc.)

Excitation current test

Visual inspection

You can avoid an unscheduled failure or outage by following a regular test schedule.

Electric transformers have been subject to failure tests

Turns ratio

Insulation resistance

Power factor

Resistance

Oil tests

Excitation current test

Analysis of Combustible Gas/Gas-in-Oil

Visual inspection (internal).
