Tfr is innovative product of taurus designed to measure impedance along with resistance of transmission line t is Salient features: Ø the equipment operates at 25 khz which and virtually isolates the parallel transmission Tower earth path without physical isolation of over head earth wire by use of this high frequency and neutralizing circuits. Ø reliable, steady, repeatable readings in induced environment Ø constant current output (20ma) from a high voltage source (250v) to override the noise in the induced environment. Ø the taurus preziohm tfr is designed to be immune to power frequency and its harmonics Ø dynamic measurement. Ø housed in ip67 pelican casing. Packaging as per international standards
