Product Description

NAJS automatic flash speed multi-position transformer calibration device, is the South Australian Electric Company to adapt to the modern transformer calibration fast and accurate characteristics of the development of a new generation of transformer calibration device. The device consists of NAJS automatic flash speed multi-position transformer calibration device, the current load box, control cabinet, current transformer test stand and other components. In the premise of maintaining the original technical characteristics 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 transformer cover, etc. have been greatly improved.

Product Features

(1) The fine adjustment of the device uses a programmable source technology, the test point of the positioning more quickly and accurately.

(2) the device in a number of current transformer measurement speed has been a qualitative improvement in the 3-5 minutes of time can be measured in any of 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 of 2.5VA-60VA, the voltage load box configuration 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 can specify the measurement of any percentage of the measurement.
