For a constant impedance load or a constant current load, if regulating the secondary voltage by making the changer ratio higher, the primary voltage will get much lower while the load power is restoring, and the power will then lose balance. For a constant power load or a motor load, since the change of OLTC has no or little influence on the load power, the voltage of primary side almost has no change whether the tap operates or not. The influence on the voltage stability with respect to the dynamic restoring load which is sensitive to voltage is also discussed.

对于恒阻抗和恒电流型负荷，在变比上调恢复副边电压的情况下，负荷功率恢复，又使原边电压下降，可使系统功率失去平衡，而对于恒功率负荷和电动机负荷，OLTC的变化不会引起负荷功率的恢复，OLTC的变化对系统电压稳定有利；同时研究了对于一般电压敏感和具有动态恢复特性的负荷，反调分接头对电压稳定性的影响。
