1. A power meter, comprising:
a housing attached to a conductor;
a hall-effect current sensor disposed in the housing and contactlessly sensing a current of a conductor signal transmitted along the conductor;
a voltage sensor disposed in the housing and contactlessly sensing a voltage of the conductor signal;
a shielding disposed in the housing and electromagnetically shielding the hall-effect current sensor and the voltage sensor; and
a printed circuit board disposed in the housing, the hall-effect current sensor, the voltage sensor, and the shielding are disposed on the printed circuit board, the shielding has a pair of panels each extending at an angle from the printed circuit board, the hall-effect current sensor and the voltage sensor are disposed between the panels.
