1. A monitoring system configured to sense two or more electrical parameters in an electrical power circuit, comprising:
a sensing module comprising:
a housing having an outer housing wall and an inner housing wall, the inner housing wall defining an inner opening of the sensing module, the inner opening configured to permit a power circuit conductor of the electrical power circuit to pass therethrough;
a current transformer (CT) supported by the housing and configured to output a signal representative of a quantity of electrical current present in a power circuit conductor passing through the inner opening; and
an antenna supported by and embedded inside the housing and configured to sense an electric field generated by the power circuit conductor, the electric field related to the electrical potential present in the power circuit conductor, whereby
the antenna senses the electrical potential present in the power circuit conductor passing through the inner opening independent of whether electrical current is present in the power circuit conductor.
