5 KV Insulation tester ,Megger make Model : BM5500 is a mains powered as well Builtin battery operated . These instruments have digital and analogue arc display, designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear and industrial installations. DC insulation tests are performed at 250 V, 500 V, 1000 V,2500 V and 5000 V . Megger BM5500 Insulation resistance measuring range is 100 kΩ to 1000 GΩ. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed. 5 KV Megohmmeters are high-voltage, line-operated instruments and they provide a continuously variable test voltage for highly sensitive insulation-resistance measurements of all types of electrical equipment and power cable.
The guard terminal in 5kV Digital Insulation resistance tester BM5500 can be used to minimise the effects of surface leakage and hence erroneous measurements when carrying out insulation resistance tests. Three insulation resistance (IR) test modes are provided, (InS, PI and t) and available in any IR test range. In IR mode (InS) tests in 5KV IR Tester are initiated by pressing and holding down the TEST button for two seconds and terminated by a second press of the button.Digital Adiradh offers best discount price for 5KV Insulation Testers in India
A Polarisation Index (PI) mode performs a ratio metric test that calculates the ratio of insulation resistance at ten minutes to insulation resistance at one minute. The IR test timer (t) mode facilitates a single fixed time test based on the set time interval t. 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’.
