WebNov 10, 2005 · Re: High Resistance Grounding Device type "59" is an overvoltage detection relay. Device type "59G" detects an overvoltage condition in the ground wire. I infer that this device senses a ground fault from the fact that current flowing in the ground wire will create a larger than normal voltage. I do not know what that "pulsing contactor" might be. WebFeb 24, 2024 · Resistance and Impedance Meet in High-Speed PCB Design In high-speed PCB design, the goal in system design and power routing in the PCB is to ensure stable power reaches fast digital components. We also want to ensure that there is minimal resistive power loss along the current path in the PCB.
