a) The indication of the stator PMA323BE  exceeds the normal value and moves back and forth violently. This is because the angle between the parallel electromotive forces has changed, resulting in a difference in electromotive forces, causing circulating currents to flow between the generators. Due to the oscillation of the rotor speed, the angle between the electromotive forces varies, and the torque and power also vary, resulting in varying degrees of circulating current. Therefore, the pointer of the stator current swings back and forth. This circulating current, combined with the original load current, may exceed the normal value.

b) The PMA323BE  readings of the stator voltmeter and other busbar voltmeter are below normal and oscillate back and forth. This is because the angle between the potential of the out of step generator and other generators is changing, causing voltage oscillation. Because the current is higher than normal, the voltage drop is also higher, causing a lower voltage.
c) The PMA323BE  and reactive loads fluctuate greatly and violently. Due to the varying power output during the oscillation process of the generator before losing step, as well as the fact that active power is sometimes output and sometimes absorbed during the loss of step

d) The pointers of the rotor voltage and ammeter swing around the normal values. When the generator oscillates or loses step, alternating current is induced in the rotor winding and fluctuates with the fluctuation of stator current. This current is superimposed on the original excitation current, causing the pointer of the rotor ammeter to swing around the normal value.
）The frequency PMA323BE  swings high and low. When oscillating or out of step, the output power of the generator constantly changes, and the torque acting on the rotor also changes accordingly, resulting in a change in speed
