Does the frequency sweep range cover the required frequency band? Transformers of different capacities and voltage levels have different characteristic frequency bands for winding deformation. The frequency sweep range of the HZ-6200 is set to 0.5kHz～2MHz, which can cover the frequency response method testing needs of most distribution transformers and power transformers. During procurement, the parameters of the equipment under test can be compared to confirm whether the frequency band meets on-site use requirements.
Can the frequency sweep mode and number of points be flexibly set? On-site testing conditions vary, so the requirements for sweep intervals and number of points also differ. This model supports optional linear and logarithmic sweep modes, and the sweep interval and number of points can be set arbitrarily according to actual needs. When confirming the technical agreement, procurement personnel can accordingly propose specific test configuration requirements.
How accurate is the frequency output? The frequency accuracy of the sinusoidal signal output by the signal source is no greater than 0.01%, which helps ensure the repeatability and comparability of the frequency response curve. For occasions requiring multiple measurements and longitudinal comparison, this indicator is one of the reference items for procurement evaluation.
This instrument is suitable for frequency response method detection of power transformer winding deformation and can be used for factory tests, handover acceptance, and periodic testing during operation. During procurement, it is recommended to also confirm whether the supporting test cables, fixtures, and analysis software are complete, so that testing can be carried out directly on site. Specific technical parameters are subject to the product manual.
