    The Megger BM15 is a compact 5 kiloVolt insulation tester that is easy to use & provides accurate and quick readings for insulation resistance.

    The Megger BM15 is an analogue insulation resistance tester that can be used to measure from 100kΩ up to 20GΩ with four test voltages of 500V, 1kV, 2.5kV and 5kV.

    Suitable for use both indoors and outdoors thanks to a rugged protective case, the Megger BM15 can be used absolutely anywhere you need it. With safety recessed terminals built-in and long connectors, the BM15 can be connected up safely to a wide variety of installations such as machinery, transformers, switchgear, cables and others.

    When testing long term, the BM15 has a locking button to make these testing procedures easier to perform. It is also possible to use non-locking testing as well.

    A scale plate overlay can also be added to the BM15, allowing quick evaluation of go/no go testing to be performed. This enables the user to evaluate the safety of the system and decide whether testing can be safely performed or not.

    Insulation is crucial for electrical system safety, providing barriers to deadly live conductors. Electrical insulation deteriorates from effects of heat, sunlight and moisture. Reductions in insulation resistance values may lead to potentially dangerous situations caused by electric shock, or fire caused by arcing. If insulation resistances are monitored regularly, low irregular values may be investigated before causing damage, inconvenience & high costs associated with equipment repair downtime.

    The BM15 is a 5 kV general purpose, insulation tester for engineers and electrical contractors that test switchgear, transformers, cables, machinery, etc. and can be used by
    • Telecommunications Engineers
    • Maintenance Engineers
    • Electrical Contractors
    • Cable Manufacturers
    • Railway Companies
    • Gas & Water Utilities
    • Mining Companies
