quick overview :

D.C. Motor coupled with A.C. Alternator (Rotating arm type or Salient pole type)

• Outer yoke made up of High permeability steel.
• Larger size of bearings for longer life and trouble free operations.
• Suitable copper conductor with best quality insulated material used to give continuous duty.
• Skewed Rotor construction with dynamically balance ensuring low noise.
• Vacuum pressure impregnation for armature and field windings ensuring high in sulation strength.
• Revolving Armature-Fixed Pole type or Salient pole Type.
• Voltage regulation within limit as per ISS.
• Special guard also provided on the coupling to avoid any mishappening during operation.
• Ratings Available both in 1phase/3phase at 0.8 P.F.

• To measure negative sequence & zero sequence reactance of Synchronous machines.
• To determine the direct axis (Xd”) and quadrature axis reactance's (Xq”) of an Alternator.
• To determine the sub transient direct axis (Xd”) and quadrature axis reactance's (Xq”) of Salient pole
