The stability of bus protection is

The stability of bus protection is of paramount importance. Bearing in mind the low rate of fault incidence, amounting to no more than an average of one fault per busbar in twenty years, it is clear that unless the stability of the protection is absolute, the degree of disturbance to which the power system is likely to be subjected may be increased by the installation of bus protection. The possibility of incorrect operation has, in the past, led to hesitation in applying bus protection and has also resulted in application of some very complex systems. Increased understanding of the response of differential systems to transient currents enables such systems to be applied with confidence in their fundamental stability. The theory of differential protection is given later in section 15.7.

母线保护的稳定是至关重要。铭记率低的故障率，相当于一个故障母线每平均不超过二十年，很明显，除非稳定性的保护是绝对的对于电力系统可能受到的干扰的程度可能增加的母线保护安装。误操作的可能性有，在过去，导致犹豫中应用母线保护，也造成一些非常复杂的系统中的应用。加深对暂态电流的微分系统响应使这种系统能够应用于其基本稳定充满信心。第 15.7 条后面给出的差动保护理论。

母线保护的稳定性是非常重要的。铭记故障发生率低，共计不超过平均二十年每个母线一个故障的，更是明确表示，除非保护的稳定性是绝对的，干扰的程度而电力系统是可能的要经受可以增加由安装母线保护的。不正确操作的可能性有，在过去，导致毫不犹豫地施加母线保护，并且还导致一些非常复杂的系统的应用。增加微分系统的瞬态电流响应的理解，使这类系统在他们的基本稳定的信心得到应用。差动保护的理论是15.7节后面给出。

母线保护的稳定性是最重要的。牢记故障发生率较低，总价不超过平均每一故障母线的二十年，很明显，除非保护的稳定性是绝对的，一定程度的干扰，电力系统可能会受到可提高母线保护装置。不正确的操作的可能性，在过去，导致在应用总线保护的犹豫，也导致了一些非常复杂的系统的应用。增加的理解的瞬态电流的差分系统的响应，使这样的系统将被应用在他们的基本稳定性的信心。微分保护理论是在第15.7节中给出的。
