BY2677EA Insulation Resistance Tester

Product Overview:
Testing the insulation resistance of different components in a system (transformers, switchgear, conductors, motors, etc.) helps isolate and repair faulty parts. Insulation testing is critical for verifying the insulation integrity between the equipment and ground or adjacent conductors, ensuring product quality, as well as personal and equipment safety during operation. Conducting insulation testing prior to energizing the system confirms its integrity and enhances system performance. Such testing can reveal manufacturing process issues and equipment defects that typically remain undetected before a failure occurs. In the European Union, this test is mandatory, even for the smallest residential systems.

Performance Features:

1.Designed in strict compliance with safety standards, with output voltages: 250V, 500V, 1000V, 2500V, 5000V, and 10000V.

2.Built-in self-check function to automatically detect whether the measurement circuit is operational.

3.Automatic discharge: Automatically discharges the tested device after completion of the test.

4.Voltage boost alarm: A buzzer alerts users to high-voltage output during operation, ensuring personnel stay clear of the testing area. The alarm stops automatically after the test.

5.Real-time display of device status: Check (self-test mode), Wait (standby), Start (measurement in progress), and END (measurement completed).

6.Battery level display and under-voltage alarm protection (with intelligent battery charging management).

7.Auto-shutdown function: The instrument automatically powers off 10 minutes after the test concludes.

8.Short-circuit protection: Halts testing if excessive leakage current is detected under short-circuit conditions.
