点击图片查看原图NAJS automatic flash speed multi-position transformer calibration device, is the South Australian ElectricCompanytoadapt to the moderntransformer calibration fast and accurate characteristics of the development of a new generation of transformer calibration device. The device consists of NAJSautomaticflashspeedmulti-position transformer calibration device, the current load box, control cabinet, current transformer test stand and other components. In the premise of maintainingtheoriginaltechnicalcharacteristics of the current transformer in the rapid measurement of the rapid positioning of test points, and the load box, a variety of variable ratio of the transformercover,etc.have beengreatly improved.
Product Features
(1) The fine adjustment of the device uses a programmable source technology, the test point of the positioning morequicklyandaccurately.
(2) the device in a number of current transformer measurement speed has been a qualitative improvement in the 3-5 minutes of timecanbemeasured in anyof the twelve transformers than any current transformer.
(3) The device is equipped with 5A standard current transformer, the current load box configuration 5A load value of2.5VA-60VA,thevoltage load boxconfiguration 100V load value from 1.25VA-158.75VA basically meet the requirements of users. The load box can be switched automatically during measurement.
(4) The device can be used for the regulation of the transformer and non-regulation of the measurement, the user canspecifythemeasurement of anypercentage of the measurement.
