Abstract
A non-intrusive, annular, broad range current sensor is located about the transmission line at the shorting location of the shielding device. Effectiveness of the shielding of the device can be readily determined for any particular predetermined frequency or range of frequencies by noting the current sensor readings and output voltage. That is, the lower the output voltage/sensor voltage readings in the test frequency range, the higher the shielding effectiveness of the device.
