VEER make Toroidal Core Tester VCT is portable 81 easy to use Instrument. It is very useful to measure AC magnetic properties of Electrical steel like AT/cm, Watt/kg, Flux Density (Induction in Tesla / Gauss) etc of Toroidal cores of different grade and size. We provide Free Computer software along with VCT. We provide Software to Generate Test Report in Excel file. You can also plot B/H Graph.

Theory of Operation

There are two windings primary and secondary, which have same number of turns. After calculating core Area of Toroidal Core we can test it using this Instrument by applying respected test Voltage as required for different Induction. We are measuring Current of Primary winding & Voltage from secondary winding to find Losses, Induction & Magnetizing Force of Toroidal Core.
