Other Details

PREZIOHM TFR is one of the innovative products of TAURUS, specially designed system to measure the earth impedance of transmission towers. PREZIOHM is a highly rugged testing instrument performs accurately in all conditions. PREZIOHM TFR are high frequency earth analyzer, used to measure the power systems ability to discharge transient energy in to ground whilst minimizing earth potential rise, ensuring the equipment and personnel are safe from any danger. It is one of the important factors in determining the effectiveness of a lightning or surge protection system.

Distinct Advantages Application & Utility :

PREZIOHM accurately tests the tower footing impedance without the influence or effects of adjacent tower earthing, station earthing & without disconnecting the earth wire.

Fall Potential Method:

PREZIOHM TFR works on principle of three peg/fall of potential method, this method is widely accepted method of earth impedance measurement.

Key Feature:

PREZIOHM TFR is a portable system that uses High frequency impulse measurement technique to measure earth impedance which enables the user to test the system without isolating the ground wire of the tower and also the testing can be carried out even when the line is energised. The Use of HF impulse signal ignores the effects of distant earth measurement due to the inpendence presented by their inter connecting cable (Ground wire).

• Direct reading digital display
• Complete suppression of induction and leakage power frequencies & its harmonics
• For low frequency (Power) the earthing is a pure resistance and for high frequency (Lightning) the earthing is inductive and hence impedance is to be measured
