A method and system to detect and evaluate improper grounding/grounded bonds in an electrical power system is disclosed. An example method is detecting improper grounding in an electrical power system having a plurality of monitoring devices coupled to a grounded conductor and a grounding conductor. Data of the voltage between the grounded conductor and the grounding conductor is received from the plurality of monitoring devices. The spatial orientation of the data from the plurality of monitoring devices is determined within a hierarchy of the electrical power system. The voltage data received from the plurality of monitoring devices is compared to determine a bond (or lack of a bond) between the grounded conductor and the grounding conductor.
