Description
The Megger BM5200 insulation resistance tester is a battery powered insulation tester with digital and analogue arc display. It has been designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear, and industrial applications.
The unit performs DC insulation tests at 250 V, 500 V, 1000 V, 2500 V, and 5000 V and its insulation resistance measuring range is 100 k Ω to 1000 G Ω. It also provides automatic discharge for capacitive circuits under test as well as displaying the decaying voltage.
The BM5200 comes with a guard terminal which can be used to minimise the effects of surface leakage and hence erroneous measurements when carrying out insulation resistance tests.
For capacitive test objects, the instrument will automatically discharge through an internal resistor and indicate voltage across the terminals in the range 25 V to 600 V with higher voltages indicated by “>600 V”. This feature will give decaying voltage indication following the testing of reactive loads. When the voltage indicator disappears, it is safe for the user to disconnect the test leads. The instrument’s safety features include high voltage warning indicator, external voltage display after IR test, automatic discharge of reactive loads, and test leads.
