productdescription

najs automatic flash speedmulti-position transformercalibration device, is the south australian electric company toadapt to the modern transformer calibration fast and accuratecharacteristics of the development of a new generation oftransformer calibration device. the device consists of najsautomatic flash speed multi-position transformercalibration device, the current load box, control cabinet, currenttransformer test stand and other components. in the premise ofmaintaining the original technical characteristics of the currenttransformer in the rapid measurement of the rapid positioning oftest points, and the load box, a variety of variable ratio of thetransformer cover, etc. have been greatly improved.

productfeatures

(1) the fine adjustment of the device uses a programmable sourcetechnology, the test point of the positioning more andaccurately.

(2) the device in a number of current transformer measurement speedhas been a improvement in the 3-5 minutes of time canbe measured in any of the twelve transformers than any currenttransformer.

(3) the device is e with 5a standard current transformer,the current load box configuration 5a load value of 2.5va-60va, thevoltage load box configuration 100v load value from 1.25va-158.75vabasically meet the re of users. the load box can beswitched automatically during measurement.

(4) the device can be used for the regulation of the transformerand non-regulation of the measurement, the user can specify themeasurement of any percentage of the measurement.
