5KV Insulation resistance tester-BM5550

Description

5KV Insulation resistance tester-BM5550

5 KV Insulation tester, Megger make Model : BM5500  is a mains powered  as well Built-in 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’.

5KV Insulation resistance tester-BM5550 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  Megger BM5500 tester uses includes:

Product test and qualification

Installation of equipment

Routine maintenance

Problem resolutions

Insulation testing with high voltage DC affects insulation polarization such that consecutive testing without complete discharge of the unit under test will yield different results in Megger 5000v Insulation Tester ..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 in Digital 5KV High Voltage Insulation Testers. Portable insulation resistance testers and megohmmeters are designed to help prevent hazards such as electric shock and short-circuits caused when the insulation in electrical devices, parts, and equipment used in industrial plants, buildings, and other settings degrades over long periods of use.
