串联补偿技术原理和一般的电压调节措施原理是一致的，就是利用各种设备和线路对配电线网电压进行调节。根据大量实验所得出的电压补偿量与配电线网所承载的电流成正比，串联补偿将把电容器线路进行串联被设置相关的电压电流监控设备，减少配电线网中有效的电抗，或是由于线路材料问题造成的电阻，造成配电线网首尾之间存在一定的电压补偿量，延长对瞬间错误信息的传递，使得配电线网内部设备可以对高电压和低电压信息进行正确处理，提升配电线网整体的供电能力。综上所述，可以知道串联补偿技术原理其实就是控制配电线网中线路负荷量，有效的降低电压补偿量，从而减少电流补偿问题的出现，解决10kV配电线高压与低压问题。电容器保护。电容器是由两个电极及其间的介电材料构成的，主要发挥着储存电能和转换电能的作用，即其自身會自动以另一种状态储存10kV配电线网中多余的电能，在10kV配电线网中缺少电能时，自动将自身储存电能转化成配电网可以使用的电能，以能够支持配电线网内部的正常使用和运作。针对电容器发挥的作用，串联补偿技术主要是通过避免电容器出现过负荷和不平衡现象来对电容器进行保护，在各个10kV配电线网中设置电压和电流监控系统，并定期对电压电流数值与正常数值进行比对，一旦发现高电压或是低电压现象，便立即拉起危险警报提醒相关工作人员进行检查。MOV保护。串联补偿技术对MOV保护分为四部分：过电流保护、能量保护、温度保护和不平衡保护，过电流保护和不平衡保护原理同上文对电容器保护是相同的，都是在配电线网中加入监控设备，并依据监控设备内部相关数据信息和标准信息比对结果，再决定下一步流程操作是否继续；相对于以上设备对故障稳定发现的及时性，能量保护和温度保护发现故障问题的速度就会慢一些，因为其是采用积分曲线的形式，对一段时间内部的MOV电流积分和定值进行比较。
