The essential property of any transformer is the number of winding turns and hence, the turns ratio. By using the turn counter – it is possible to measure the number of turns with high accuracy in a cost efficient way.
Winding turn determination is a vital step in transformer production and repair.
For example, in the transformer production process, the number of turns must be measured before installing the winding on the core. When a transformer is repaired, the number of turns has to be determined in case the winding has to be rebuilt and design drawings are not available.
