Automatic Voltage Regulators May Cause Neutral Line Potential Drift During Voltage Regulation.

In actual power systems or single-unit power generation devices, when the output voltage of the 100 kva stabilizer is dynamically regulated, its performance relative to the neutral point or zero line will also be affected by system conditions. The neutral wire should theoretically be kept at the same potential as the ground and play the role of reference potential in a three-phase power distribution system. However, this ideal state may deviate in certain voltage regulation operations. This potential shift is known as neutral point drift or zero-line potential drift, and it is closely related to the feedback and response mechanism of the 10000 kva stabilizer.

The control logic of the 10kva automatic voltage regulator is based on real-time monitoring of the difference between the output voltage and the desired value, and adjusts the excitation or built-in transformer accordingly to correct the voltage. Since the neutral wire serves as a reference in the entire voltage control loop, when the adjustment ratio or excitation level changes, if the system load is unbalanced or the grounding conditions are not ideal, the potential between the neutral wire and ground may deviate. This deviation is not a "mistake" of 10kva automatic voltage stabilizer itself, but rather reflects a physical change in the neutral point of the system, such as the neutral point migrating to a non-zero potential when there is a three-phase imbalance.

In a power grid or local power supply system, unbalanced three-phase loads, high neutral line impedance, or increased grounding point impedance can all amplify this drift phenomenon. When load differences cause the neutral point to no longer be strictly at the design potential, the 10kva stabilizer single phase timer will respond to the measured voltage deviation when adjusting the single-phase or overall voltage. With this adjustment, the neutral potential may no longer be stable.
