SCB11 Dry-type Transformer How to measure

SCB11 dry-type transformer is also to measure a variety of data, SCB11 dry-type transformer measurement data in the process of SCB11 dry-type transformer is a variety of physical quantities are constantly tested, in fact, the performance of SCB dry-type transformer is through the test to go to understand. For SCB11 dry-type transformer common measurement method and the main measurement of the content you know how much? Together and to come andSCB11 dry-type transformer manufacturer's editor to understand it in detail:

Measurement of power failure: SCB11 dry-type transformer is generally composed of two 

or more groups of coils. In general, the enameled wire diameter of each group of coils is 

the same, so by measuring the DC resistance value of each winding can determine its 

good or bad. The higher the power the smaller the resistance value, the lower the power 

resistance value is large.

Such as using a multimeter to test the DC resistance value of a winding for infinity, that indicates that the winding is open circuit, if the DC resistance value of the winding is significantly smaller than the resistance value provided by the manufacturer, it indicates that there is a short circuit in the winding or the wrong specifications of the enameled wire and so on.

Energized measurement: after energized, scb11 dry-type transformer without obvious abnormal sound, surface temperature without significant increase, and then use the multimeter AC AC file to test the output voltage of each winding is in line with the requirements of the output no-load voltage, and vice versa is determined scb11 dry-type transformer there is some kind of defect.

The above is common SCB11 dry-type transformer measurement of the main way and the main measurement of the content for your reference.
