Product Code : SCL-EELE-12950
Indian Lab Suppliers supplies the Measurement of Xd and Xq of Three Phase Synchronous Machine (Product ID: 12950) as part of its electronics engineering lab equipment range. It is a DC motor and synchronous machine set for measuring the direct-axis and quadrature-axis reactances of a three-phase synchronous machine.
Quick Answer
A 2 HP, 200 V DC shunt motor, started through a three-point starter, drives a 3 HP, 415 V, 1500 rpm star-connected synchronous machine with 120 V excitation. In the usual slip test the machine is run slightly off synchronous speed with its field open and a reduced three-phase voltage on the armature; Xd is found from maximum voltage over minimum current and Xq from minimum voltage over maximum current. The set is also used to find positive, negative and zero sequence impedances. A DC supply (fixed 200 V and variable 0–200 V) feeds the motor and field, and low-range 20 V and 2 A AC meters suit the reduced-voltage tests.
