  • Tower Footing Earth Impedance Measurement Instrument - India

    price: contact company for price

    TFR is innovative product of TAURUS designed to measure

    impedance along with resistance of transmission line tower footing without disconnecting the overhead earth wire. The tower earthing has an important influence on a) Reducing the number of Faults in power system. b) Dealing with effects of proximity between power system and railway or telecommunication systems & c) Ensuring the safety of people near tower.

    TFR is a high frequency earth tester, used to measure the tower earth resistance to discharge transient power frequencies in to ground ensuring the equipment and personnel are safe from any hazard. Also useful in determining the effectiveness of lightning or surge grounding capacity of

    any tower by measuring the tower footing impedance.


    PREZIOHM TFR is a portable system specially designed to measure impedance and resistance of transmission line tower footing without necessitating removal of top ground wire.

    PREZIOHM TFR has a wide measurement range ( 0to 2k ohms) and is immune to power frequency interference and its harmonics. The instrument is designed to operate in a highly induced environment and to give highly stable, reliable, repeatable readings with its strong

    capability of noise & leakage current/ voltage suppression.


    Ø Measures impedance along with resistance of the transmission line tower footing without isolating overhead earth wire

    Ø Automatic suppression of all noise and leakage currents

    Ø Metallic shielding to suppress EMI interference and EMC compliance

    Ø Dynamic measurement

    Ø Rock steady, reliable and repeatable readings in induced environment

    Ø High capacity battery for long and continuous operation

    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


    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


    Ø Principle of operation : Fall of potential ( 3 point) with high frequency

    Ø Application Soil resistivity and ground resistance measurement

    Ø Range : 0.01Ω to 2 kΩ

    Ø Voltage output : 250V

    Ø Frequency : 25 kHz as per IEEE 81- 1983

    Ø Short circuit current : 20mA

    Ø Measurement Accuracy : +/ - 5%

    Ø Graphic LCD display with high resolution

    Ø 12V, 7Ah rechargeable maintenance free battery for long and continuous operation

    Ø IP 67 pelican casing
