10kV配电线高压与低压问题，顾名思义就是在标准电压情况下，由于某种原因造成10kV配电线网内部的线路电压呈现一种不稳定的情况，而通常这种不稳定情况往往伴随着电压的剧烈变化，进而造成监控10kV配电线的电压器数据偏高或是偏低，给人们的人身安全和各种安全事故埋下了巨大隐患。一般造成10kV配电线高压与低压问题的原因分为两种，包括人为原因和外界干扰原因。人为原因很简单就是在配电线网正常运行，技术人员进行错误的流程操作或是输入错误的数据信息，从而造成线网短时间内被破坏，出现高电压或是低电压现象，配电线网运行系统瘫痪；相对可控制的人为原因，外界干扰因素则是令供电部门十分苦恼，尤其是在丰水季节，大量降雨、雷电和潮湿环境都会对10kV配电线网造成一定损坏和侵蚀，运行系统不稳定，配电线网中的电压也不稳定，两者运行一直呈现恶性循环，缩短用电设备的使用寿命，增加用电的危险性。随着技术人员自身专业水平的提高，造成10kV配电线高压与低压问题的主要原因还是外界因素干扰，但不论是哪种原因造成高电压和低电压问题，最根本的因素还是10kV配电线高压与低压调节技术，则如何在配电线网被破坏或是被干扰的情况下，调节10kV配电线网整体电压处于正常电压状态下，成为解决10kV配电线高压与低压问题的主要措施。根据上文对10kV配电线高压与低压问题的分析，可以知道造成高电压和低电压问题的根本因素是电压调节因素，因此，供电部门往往会采用以往的经验进行电压调节，例如：并联配电线网整体电容和电压调节器，进而控制配电线网电压范围，再者就是并联电抗器和电压调节器，同样也能控制配电线网电压范围。虽然采用以往经验也能有效的解决10kV配电线高压与低压问题，但在实际建设和操作中存在着众多问题，以文中并联电抗器和电压调节器为例子，首先电压调节器的频繁使用会对配电线网造成一定的损伤，而且在一定情况下，电压调节器不仅不能使用还会阻碍电抗器的正常使用，进而造成配电线网长时间处于超负荷状态，进而增加高电压和低电压问题出现的频率。因此，为确保配电线网的正常运行，一般供电部门用串联补偿技术代替一般的电压调节措施。
