Ensuring Safe and Reliable Tower Earthing with Precise Impedance Measurement
The Taurus PREZIOHM TFR is an innovative product by MKS, designed to measure the impedance, resistance, and inductance of transmission line tower footings without disconnecting the overhead earth wire. This portable system is specially engineered to operate in highly induced environments and is essential for:
- Lightning Protection: Ensuring effective earthing for lightning protection by measuring tower foot impedance.
- Safety Assurance: Protecting people near the tower from lightning strikes by assessing the grounding system’s effectiveness.
Necessity of Measuring Tower Foot Impedance
Lightning strikes can severely impact transmission lines and their insulators, particularly if the tower earthing is inadequate. To assess the effect of lightning on a particular tower and take corrective action, it’s crucial to measure the tower foot impedance. A reliable measurement helps prevent damage and enhances safety
The PREZIOHM TFR is a high-frequency earth tester that measures the resistance of tower earthing to transient frequencies caused by lightning strikes. It ensures the safety of equipment and personnel by ensuring the effective discharge of lightning energy into the ground.
Additionally, it helps in evaluating the performance of surge or lightning grounding systems by providing impedance measurements for tower footings. The instrument boasts a wide measurement range (0 to 2k ohms) and is immune to power frequency interference and harmonics.
Built to withstand induced environments, the PREZIOHM TFR guarantees stable, reliable, and repeatable results, even in challenging conditions, with superior noise suppression capabilities.
