To perform OC & SC test on a 3 phase transformer & find its
efficiency and parameters for its equivalent circuit.
-
To perform parallel operation of two 3-phase transformer and determine
their load sharing.
-
To study the performance of 3-phase transformer for its various
connections, i.e. star/star delta delta/star and delta/delta and find the
magnitude of 3rd harmonic current.
-
To make scott connection and measure the phase difference of secondary
voltage by (i)voltmeter method (ii) CRO method.
-
Separation of transformer core losses and to determine the hysteresis and
eddy current loss at rated voltage and frequency.
-
To plot the O. C. C & S.C.C of an alternator and to determine its
regulation by syncoronous impedance method.
