3.4.30 STRW - Stress Wattage

The Stress Wattage test tests the transformer for breakdown of insulation by measurement of the energizing power of a winding, usually the primary, with the remaining windings open circuit. This test applies the voltage, usually twice the normal operating voltage, and continually measures the power to determine any breakdown by changes in the measurement.

This test is suitable for subminiature line frequency, large line frequency bobbin wound and some HF transformers. It checks the integrity of interturn insulation, the magnetic material and joints.

On selecting "STRW Stress wattage" from the available tests window, a form fill-in dialogue box will be displayed:

To program the test:

  1. Enter the voltage and frequency parameters of the test signal.
    (If in doubt, refer to Chapter 7 - ‘Test Conditions’, which lists recommended test conditions for different values of inductance.)
  2. Select the Dwell time you require.
  3. Enter the names of the Hi and Lo terminals.
  4. Set maximum power limit.
  5. Select OK. The test specification will then be displayed in the program window.
