WebFeb 17, 2007 · Also.. Even without saturation, a 1000VA line frequency transformer is going to use a lot of power under no load - while googling for the above I saw ~5% core losses, which don't decrease when the load is removed, that means ~50W - so a lot better to turn it off. posted by Chuckles at 9:37 AM on February 17, 2007 WebMay 29, 2024 · 2. Confirm the proper input to the transformer. Apply power to the circuitry. Use the DMM in AC mode to measure the transformer primary. If the measurement is less than 80 percent of the expected voltage, the fault could lie in either the transformer or the circuitry providing the primary with power.
