本推荐规程为用户提供了控制或修改感应环境和受影响的有线通信设施敏感性的帮助，以便在IEEE Std 776（TM）定义的环境接口（探测线）的稳态或浪涌感应电压的可接受水平内运行。1方法、应用，对于所有特定的A类和B类协调方法，应对缓解技术或装置的结果进行评估 IEEE标准776。

This Recommended Practice offers users assistance in controlling or modifying the inductive environment and the susceptibility of affected wire-line telecommunications facilities in order to operate within the acceptable levels of steady-state or surge-induced voltages of the environmental interface (probe wire) defined by IEEE Std 776(TM). The methodology, application, and evaluation of results for mitigative techniques or devices in general are addressed for all Specific Type A and Specific Type B coordination methods also defined by IEEE Std 776.
