LQ-5600 Earth Resistance Tester: Double Clamp Non-Contact Measurement

The LQ-5600 Earth Resistance Tester by Wuhan UHV is a handheld instrument designed for measuring grounding resistance in industrial environments. With its patented double-clamp non-contact technology, it enables on-site testing without disconnecting grounding systems, making it ideal for telecommunications, power grids, gas stations, and factory grounding networks.

Technical parameters

Key Features

1. Dual Measurement Methods

• Double Clamp Method: Non-contact measurement for live systems (no auxiliary poles needed)

• Ground Pile Method: Traditional measurement for single-point grounding

2. Advanced Technology

• Anti-Interference Design: Filters 50Hz/100Hz harmonics, even in 500kV substations

• Wide Measurement Range: 0.01Ω–200Ω with 0.01Ω resolution

• Large Jaw Design: 50mm diameter accommodates flat steel/iron grounding leads

3. User-Friendly Operation

• No specialized training required

• Chinese/English interface options

• 200-data-point storage capacity

• Portable explosion-proof case

Industrial Applications

The LQ-5600 is widely used for:

• Power Distribution: Testing transmission towers, substations, and distribution lines

• Telecom: Ensuring signal tower grounding safety

• Gas Stations & Factories: Compliance with lightning protection standards

• Renewable Energy: Solar/Wind farm grounding system maintenance

Why Choose the LQ-5600?

Unlike traditional testers, the LQ-5600 eliminates the need for:

1. Disconnecting grounding conductors

2. Deploying auxiliary electrodes

3. Manual data recording (with 200-set storage)

Its patented double-clamp technology and high-frequency current generation ensure accurate measurements even in high-interference environments like 500kV substations. Custom jaw sizes are available for specialized applications.

Note: Complies with IEC 61010 safety standards for electrical testing equipment.
