大多数工程师和技术人员都曾经连接过各种设备组合，发现输出包含过多的60赫兹干扰。在这些情况下，解决方案通常是除去系统中的所有接地，只留下一个，并在每个设备上安装一条独立的接地线。这有时需要对与交流线路耦合过度的设备使用单独的隔离变压器。
Most engineers and technicians have at one time or another connected various combinations of equipment and found that the output contained excessive 60-Hz interference. In these instances, the solution has normally been to remove all grounds in the system except one and install an independent ground wire from each piece of equipment to this point. This sometimes required the use of separate isolation transformers for equipment that had excessive coupling to the ac line.
