System and method for measuring a parameter of an alternating current power grid while minimizing the likelihood of lightning damage in a measuring system

摘要

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.

1. A method for measuring a parameter of an alternating current power grid with a measuring system that includes an antenna exposed to the sky, a signal receiver coupled to the antenna, and a measuring device coupled to the signal receiver via a cable, the method comprising:
receiving a first signal at the antenna; transmitting the first signal to the signal receiver; generating a second signal at the signal receiver; generating a third signal based on the second signal and electrically isolated from the second signal; transmitting the third signal in the cable toward the measuring device; generating a fourth signal based on the third signal and electrically isolated from the third signal; transmitting the fourth signal to the measuring device; calibrating the fourth signal by subtracting a delay constant from the fourth signal, wherein the delay constant approximates the delay between receipt of the first signal at the antenna and a receipt of the fourth signal at the measuring device; and measuring a parameter on the alternating current power grid relative to the calibrated fourth signal.
