Job Description:

• 1) Tests insulation, current resistance, loss of current, and performance of transformers and tests insulating strength of transformer oil, using electrical testing mechanisms: Attaches transformer wires to terminal board mounting various testing meters and to live wire for energizing transformer.

• 2) Adjusts testing-meter indicators at settings governed by test to be made and volt specifications on transformer tested, employing extensive knowledge of transformers.

• 3) Successively turns switches which control transmission of current through transformer to testing meters, such as voltmeter, ammeter, and ohmmeter, for testing insulation, resistance, and loss of current.
