CABLE ASSEMBLY BNC MALE TO BNC MALE E Figure 4 2 Output Signal Cable and Adapter 4 2 AC CURRENT TRANSDUCER The RR 30000 SD design utilizes the lightweight and flexibility of the AC Current Transducer This transducer is a versatile current probe that may be wrapped around most conductors Three standard lengths are available They are 24 36 and 48 inches It s application versatility and high voltage isolation rating clearly distinguishes the RR 30000 SD from other current measuring methods The measuring transducer is constructed from non ferrous materials minimizing any circuit loading The frequency response of the RR 30000 SD is wide compared to conventional CTs This allows the user to monitor a much wider range of line harmonic components than conventional CTs allow The RR 30000 SD was designed to be very flexible larger in aperture and smaller in cross section than many conventional CTs This allows measurement in tight places as never before possible Figure 4 3 Type RS5 Flexible Transducer 2011 DynAmp LLC Page 8 041143 H Installation Operation and Service Manual HIGH CURRENT PROBE The output voltage of the transducer is proportional to the product of the current and the frequency At higher frequencies the output voltage of the transducer may damage the input circuits of the electronics package Refer to Chart 4 1 and Chart 4 2 for the safe operating areas of the 3kA and the 30kA range respec
