The Importance of the BY2671 Digital Insulation Resistance Tester

In modern industrial production and power system operations, ensuring the safe and stable operation of electrical equipment is paramount. The insulation performance of electrical equipment stands as a critical factor in guaranteeing its reliability. Among the tools used to assess insulation performance, the BY2671 Digital Insulation Resistance Tester plays an irreplaceable role due to its exceptional performance and broad applicability，Meeting Diverse Application Requirements.

1. Wide Industry Coverage

The BY2671 Digital Insulation Resistance Tester is an essential instrument across industries such as power, post and telecommunications, communications, electromechanical installation and maintenance, and any enterprise reliant on electrical energy. In the power sector, it is indispensable for routine insulation resistance testing of generators, transformers, transmission cables, and substation equipment to ensure grid stability. In telecommunications, it safeguards communication devices and lines from signal interference and failures. For electromechanical installation and maintenance, the tester provides accurate insulation measurements to verify safety during commissioning or repairs of both new and existing equipment.

2. Versatility Across Insulation Materials and Equipment

The tester measures insulation resistance values for various materials and is highly effective for evaluating transformers, motors, cables, and other electrical devices. Different insulation materials require tailored testing approaches, and the BY2671 excels in adaptability and precision. For critical equipment like transformers and motors, timely detection of insulation degradation prevents operational downtime and financial losses. Similarly, cables—vital for power and signal transmission—rely on the BY2671’s accuracy to maintain reliability.

Superior Performance Ensures Measurement Accuracy

1. Robust Output Capability

High Output Power and Short-Circuit Current: With a short-circuit current exceeding 1.6mA, the tester rapidly charges capacitive loads to the rated voltage, overcoming challenges posed by complex testing scenarios.

Multi-Voltage Outputs: Four voltage levels (500V, 1000V, 2000V, 2500V) allow flexible selection based on equipment requirements. Lower voltages suit low-pressure devices, while higher voltages ensure rigorous testing for critical systems.

2. Precision and Anti-Interference Design

High Accuracy: A measurement range of 0–19999MΩ, with a relative error ≤ ±5% ±1 digit and resolutions of 0.01MΩ, 0.1MΩ, 1.0MΩ, and 10.0MΩ, enables detection of even minor insulation degradation.

Advanced Shielding: The high-strength aluminum alloy housing, combined with an equipotential protective ring and fourth-order active low-pass filter, effectively shields against industrial-frequency noise and electromagnetic interference, ensuring stable operation in harsh environments.
