5KV Insulation resistance tester-BM5500

Adiradh Energy offers  5 KV Insulation tester  BM5500 tester  is a line/mains powered only insulation tester. 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. BM5500 in India Insulation resistance measuring range is 100 kΩ to 1000 GΩ. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed in BM5500

The guard terminal in 5kV 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 are initiated by pressing and holding down the TEST button for two seconds and terminated by a second press of the TEST button.

1 TΩ, 1.4 mA, 5 kV digital insulation tester with digital and analogue display

BM5500 is a line/mains powered only insulation tester

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’.

BM5500 Features 

■ 1 TΩ, 1.4 mA, 5 kV digital insulation tester with digital and analogue display
■ Five test ranges; 250 V, 500 V, 1000 V,2500 V and 5000 V
■ Insulation (InS), Polarisation Index (PI) and variable timed test (t) modes
■ Selectable DC or AC  voltmeter functions
■ Guard terminal to shunt surface leakage currents
■ CAT III 600 V safety rating

BM5500 Applications

Electrical insulating materials deteriorate with time leading to breakdowns and costly repair bills. Insulation resistance testers apply a regulated DC voltage across the insulation and measure current flow through it applying Ohm’s law to calculate insulation resistance. 5KV  Insulation resistance tester -BM5500 tester uses includes:

Product test and qualification

Installation of equipment

Routine maintenance

Problem resolutions

Insulation testing with high voltage DC affects insulation polarisation such that consecutive testing without complete discharge of the unit under test will yield different results.Care should be taken to always employ the same process and technique of connecting to and testing an insulator to be able to trend results.
