Tower Footing Resistance, Impedance & Inductance measuring instrument
PREZIOHM TFR is an innovative product of MKS designed to measure impedance along with resistance and Inductance of transmission line tower footing without disconnecting the overhead earth wire. The tower earthing has an important influence on a) The effect of lightning strikes on the tower. b) Ensuring the safety of people near tower. PREZIOHM TFR is a high frequency earth tester, used to measure the tower earth resistance to discharge transient frequencies generated due to lightning into the 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.
Measures impedance along with resistance and Inductance of the transmission line tower footing without isolating overhead earth wire
Automatic suppression of all noise and leakage currents
Metallic shielding to suppress EMI interference and EMC compliance
Dynamic measurement
Rock steady, reliable and repeatable readings in induced
High capacity battery for long and continuous operation
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 (Oto2k 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.
