  • AC Insulation Testing

    Megger Group Ltd.

    AC insulation tests are a popular response to the increasingly demanding industrial, power and domestic marketplaces. Insulation materials have had to become more efficient to keep up with demand; more efficient equipment requires less insulation material to meet the minimum acceptable value of insulation resistance. In turn, cables have become smaller and lighter. However, under certain higher stress testing conditions such as DC testing, cables like Crossed Linked Polyethylene (XLPE) can quickly degrade.

  • Battery Extra Load Units

    BXL Series - IBEKO Power AB

    BXL is an extra load unit designed to be used with DV Power’s BLU series battery testers. However, this unit is a universal add-on device. Because of that, it is compatible, as an additional load, with any other discharge/capacity tester in the market.In case when discharge current exceeds the capacity of a single BLU device, BXL can increase the discharge capacity. There are no limitations on the number of extra load units that can be connected in parallel to the main battery tester.A system of BLU and BXL instruments enables performing the capacity test in an accurate, user-friendly way. Also, all instruments are in accordance with battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.These units can be used on any type of battery string, such as lead-acid, Li-Ion, Ni-Cd, etc. They test battery strings with voltages in the range of 5,25 – 500 V DC. On the other hand, current up to 250 A can be discharged through the BXL internal structure.The instrument simulates a constant resistance load during the discharge test. Several resistances can be set for different battery nominal voltage levels. This makes BXL extremely flexible in selecting its load capabilities.
