Megger BM5200 5 kV Insulation Resistance Tester
The BM5200 is a robust 5 kV insulation resistance tester designed for industrial and service professionals working on high-voltage equipment. With selectable test voltages up to 5 000 V DC, a measuring range up to 1 TΩ, digital and analog display, and safety-focused features such as automatic discharge and a guard terminal for surface leakage suppression, it offers reliable diagnostics for cables, switchgear, machines and other insulation systems.The BM5200 is engineered to handle demanding insulation testing tasks in maintenance, commissioning and fault finding on high-voltage equipment. It allows DC test voltages of 250 V, 500 V, 1 000 V, 2 500 V and 5 000 V, enabling flexibility across a wide range of insulation systems. The measurement capability spans from 100 kΩ up to 1 000 GΩ (1 TΩ) under 5 kV test voltage. The instrument features both a large digital read-out and analog arc display to support both precise numerical readings and quick visual feedback of trends. Safety and measurement integrity are built in: the tester includes a guard terminal to minimise surface leakage currents that can distort high-resistance readings, and after testing, it automatically discharges capacitive or reactive test objects and displays remaining voltage to ensure safe lead removal. Additional features include selectable AC/DC voltmeter function (up to ~600 V), high-voltage warning indicators, and a rugged battery-powered design. Its CAT III 600 V safety rating makes it suitable for industrial applications, and it is particularly suited for insulation testing of cables, rotating machinery, transformers, switchgear and other high-voltage assets.
