ABSTRACT:
A system for monitoring a grounding system is permanently installed in, for example, a telephone switching office. The system operates to scan a large number of ground conductors at the master ground bar by using amplified Hall effect sensors to monitor AC and DC current on the conductors. If a surge enters the telephone switching office, the surge is coupled to ground. The system monitors these ground conductors to insure that the ground system is operating properly. The microprocessor continuously insures that readings are taken of the current on each of the ground conductors. The microprocessor compares the current readings with preset parameters. If a reading exceeds the predetermined parameter threshold, an alarm report is generated. The report lists not only the current on the conductor which was the source of the surge, but also shows any current increase on the other ground conductors that are monitored. Thus, if the surge comes in on one of the ground conductors and goes out on other ground conductors and into the office equipment, the present system will indicate such and generate an alarm report to permit detection and correction of any problems.
