Different VLF units output different waveforms. What’s best?
Release Time : 2021-01-05 View Count : 次All High Voltage, Inc. VLF units produce a perfect sine wave output. The original German designs, which are still offered, do not produce a sine wave output. They produce a trapezoidal waveform. They often try to claim that it’s superior to the sine wave: a very tough argument to make. They don’t produce a sine wave VLF. How can any engineer argue with a sine wave output? Also, for a VLF unit to be used for diagnostic testing, either Tan Delta of Partial Discharge, it must produce a sine wave. The IEEE recognizes the sine wave output as advantageous and mandates it when the VLF unit is used for testing rotating machinery. Stick with a sine wave unit.
