Abstract
A measurement module receives a defined system topology and system component characteristics information for a system. The measurement module calculates an expected system impedance for the defined system topology. The measurement module collects one or more impedance measurements using a high frequency voltage stimulus. Finally, the measurement module compares the one or more impedance measurements with the expected system impedance to determine adequacy of protective grounding of the system.
Claims20
A measurement module for high frequency ground monitoring, comprising:
- at least one processor;
- at least one memory including computer program code, wherein the computer program code, when executed by operation of the at least one processor, performs an operation comprising:
- receiving a defined system topology of a system and information on characteristics of components in the system;
- calculating an expected system impedance for the system;
- conducting one or more measurements of actual system impedance of the system using a high frequency voltage stimulus;
- and
- comparing the one or more measurements of actual system impedance with the expected system impedance to determine adequacy of protective grounding of the system.
