老化延缓。低压电流是高压电流的26.25倍，低压发电机组热负荷损耗大，高压反之。

Delayed aging. Low voltage current is 26.25 times higher than high voltage current. Low voltage generator sets have high thermal load losses, while high voltage generators have the opposite effect.

抗谐波能力高。低压发电机设计结构工艺简单，所以抗谐波能力相对较低。

High harmonic resistance. The design structure and process of low-voltage generators are simple, so their ability to resist harmonics is relatively low.

非同期短路风险系数低。多台低压发电机非并机供电时，由于各供电系统不同步，存在非同期短路风险，高压反之。

The risk coefficient of non synchronous short circuit is low. When multiple low-voltage generators are not connected for power supply, there is a risk of asynchronous short circuit due to the asynchronous power supply systems, while the opposite is true for high-voltage.

安全性高。低压机组的输出断路器由于电流过大，灭弧不如高压，经常出现因拉弧损坏。

High security. The output circuit breaker of low-voltage units is not as good as high-voltage due to excessive current, and often suffers from damage due to arc pulling.

供电集中。低压发电机因电缆使用多，热损耗大很难实现远距离送电。高压机组电流小，可实现远距离送电。

Centralized power supply. Low voltage generators are difficult to achieve long-distance power transmission due to the frequent use of cables and high heat loss. The high-voltage unit has a small current and can achieve long-distance power transmission.
