Megger 5kv Insulation Tester Bm5500

The Megger BM5500 Insulation Resistance Tester is a professional-grade 5 kV digital insulation tester designed for accurate insulation resistance testing of electrical equipment in industrial and utility environments. It is ideal for testing cables, transformers, motors, generators, switchgear, panels, and other high-voltage electrical installations. The BM5500 provides five selectable DC test voltages (250 V, 500 V, 1000 V, 2500 V, and 5000 V) with an insulation resistance measurement range up to 1 TΩ (1000 GΩ). It features both a digital display and analogue arc display, along with test modes including Insulation Resistance (IR), Polarization Index (PI), and Timed Test, making it suitable for preventive maintenance and condition monitoring.

Built for demanding industrial applications, the BM5500 includes a Guard Terminal to minimize surface leakage errors, automatic discharge for capacitive loads after testing, and a CAT III 600 V safety rating for enhanced operator protection. Its rugged construction, high accuracy, and user-friendly operation make it a trusted choice for electrical maintenance professionals.
