Product Details


■ Product Overview

The tower grounding resistance tester is designed to measure the grounding resistance of transmission line towers with directly grounded overhead ground wires. It measures the resistance of both the tower structure and the overhead ground wire within the same span, as well as subsequent sections. ( or both sides ) The resistive components of the equivalent impedance in each phase‑to‑ground loop form a closed circuit. By applying the internal power supply potential of the measuring instrument, a current is generated in this circuit, and the grounding resistance of the tower under test is determined using Ohm’s law for the entire circuit.

■ Product Features

No layout is required during measurement, reducing the labor intensity of on-site surveying.

The voltage output is a high-precision, digitally controlled DC source, characterized by a wide measurement range, large output current, and extremely low ripple and interference.

LCD It simultaneously displays the voltage value, the measured current value, and the resistance, facilitating operation and error analysis.

The internal circuitry employs high-precision components and utilizes PID The algorithm performs current adjustment.

The measurement is accurate, and the measured value can be regarded as the actual tower impedance.

The instrument is equipped with built-in functions for storing and viewing measurement data.

The housing is made of a special material, offering high mechanical strength and moderate resistance to vibration and drops.
