Description

technical field [0001] The invention relates to a grounding resistance monitoring device and a monitoring method thereof, which are suitable for monitoring the grounding resistance of equipment rooms in electric power, communication, radio and television, and the like. Background technique [0002] At present, the grounding wires of the equipment in the computer room are often not detected in time due to poor contact, insulation aging and other reasons, resulting in high-impedance grounding, which can easily cause equipment damage or cause electric shocks for maintenance personnel due to shell leakage. Therefore, it is necessary to develop a grounding resistance monitoring device. Through grounding resistance monitoring, problems can be found and solved very early, so as to protect the equipment and personal safety of the user's computer room. Contents of the invention [0003] In view of this, the object of the present invention is to provide a grounding resistance monito...
