Measurement of Xd and Xq of Three Phase Synchronous Machine

Measurement of Xd and Xq of Three Phase Synchronous Machine .
Measurement of Xd and Xq of Three Phase Synchronous Machine is an exclusive product designed to demonstrate the operating principle and functioning of Three Phase Synchronous Generator. This machine lab can change the mechanical energy to electrical energy. It helps students to analyse and calculate the significant parameters such as positive, negative & zero sequence impedance, direct & Quadrature axis reactance etc. to correctly construct Three Phase Synchronous Generator.

It includes separate terminals for rheostat and three point starter provided on the control set-up so that students can make connections by themselves with adequate protections.
