Skew calibrator (used to adjust the skew of voltage and current probes)

Skew calibrator

  • This device can simultaneously generate a phase-matched voltage pulse and current pulse of up to 250V/20A, so it is ideal for skew (delay time) correction of high voltage probes and high current probes used for inverter measurement.
  • Precise power measurement can be performed by accurately correcting the skew (delay time) of voltage probes and current probes.

■ Reason for voltage waveform and current waveform skew (delay time) correction
If you do not correct the skew accurately, you will get different results from the real power loss waveform as shown in the figure below.
For high-precision power measurement, skew (delay time) correction of voltage and current probes is required.
