Summary:This paper briefly looks at the possibility of multiple simultaneous measurement of the Thévenin equivalent impedance (TEI) of a power supply grid via two points of common coupling (PCC). The paper starts by first, verifying TEl measurement device on a three-phase PCC, and then analyzing the data. The TEl measurement device used for the impedance detection is based on an active detection method. The results showed that the detection of TEl is highly susceptible to noise along the line. Simultaneous operation of the devices produce varying results which is dependent on the noise on the line during measurement periods, unrelated to the dual operation. In the absence of noise on the line, TEl measurements appear to be consistent with little variance around a mean trend and no significant interference between both devices were found.
