14.6.29. 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 inter-turn 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.
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.
