The Megger BM25 is a compact automated 5 kV insulation tester. It can be used to conduct polarization index, step voltage, dielectric discharge diagnostic and standard insulation tests up to 5 TΩ.

Results and test options are displayed on a large, clear analog/digital readout for both practicality and precision. The BM25 provides an optically isolated RS-232 port for direct download of test results. This enables the user to conduct cost-effective predictive maintenance programs.

The instrument displays leakage current down to <1 nA and the capacitance of the test piece up to 10 µF. A guard terminal allows surface leakage to be removed.

Standard test voltages are preset at 500 V, 1000 V, 2500 V and 5000 V and combined with an output voltage setting that is variable in 25 V steps. The integral timer starts automatically at the beginning of a test and can be used to control test duration.

The BM25 is powered by rechargeable lead-acid batteries. The built-in charger operates from 95 V to 265 V power supplies without switch selection. The instrument is supplied complete with test leads, RS-232 interface lead and file transfer utility software.
