Abstract: A system and method are provided for measuring a parameter of an alternating current power grid relative to a calibrated fourth signal. The method includes receiving a first signal at an antenna and transmitting it to a signal receiver. A second signal is generated at the signal receiver. A third signal is generated based on the second signal and electrically isolated from the second signal. The third signal is transmitted in the cable toward the measuring device. A fourth signal is generated based on the third signal and electrically isolated from the third signal. The fourth signal, which is calibrated by subtracting a delay constant from the generated fourth signal, is transmitted to the measuring device. The delay constant approximates the delay between receipt of the first signal at the antenna and receipt of the fourth signal at the measuring device.
