BY2571 Earth Resistance Tester: Technical Overview
The BY2571 Earth Resistance Tester is a versatile and advanced instrument designed for measuring grounding resistance, low-value conductor resistance, soil resistivity, and AC ground voltage. It is widely used in industries such as power supply, telecommunications, railways, and mining, where reliable grounding is essential for safety and system integrity.
This tester represents a significant improvement over traditional hand-cranked instruments. It incorporates advanced medium- and large-scale integrated circuits and utilizes DC/AC conversion technology. This design integrates both the three-terminal and four-terminal measurement methods into a single, efficient device.
Key Technical Features:
1.Robust Design & Anti-Interference: Housed in a high-strength aluminum alloy case, the instrument features a phase-locked loop synchronous detection circuit and a switched capacitor filter. This design effectively shields the measurements from power frequency and radio frequency interference, ensuring accuracy in electrically noisy environments.
2.Constant Current Measurement: The built-in DC/AC converter transforms DC power into a stable, low-frequency AC constant current for measurement. This provides consistent and reliable results across the specified ranges.
3.Tolerance to Auxiliary Ground Resistance: The instrument is designed to tolerate variations in auxiliary grounding resistance without significant impact on measurement accuracy. It allows resistances of 0–2 kΩ for the current auxiliary ground (RC) and 0–40 kΩ for the potential auxiliary ground (RP).
4.Ease of Use: The device requires no manual zero adjustment. Measurements are clearly displayed on a 3.5-digit LCD. It automatically indicates overflow with a "1" display if a fault is detected in the test loop.
