The Megger BVM is a battery voltage measurement device that is used for the capacity testing of large, industrial battery banks commonly found in electrical power sub-stations, telecom facilities and computer data center UPS systems.
When used in conjunction with a load device, such as the TORKEL unit, and test data management software, such as PowerDB and TORKEL Win, the BVM enables to perform a completely automated battery bank capacity test, according to IEC test method.
The test also meet NERC/FERC requirements. The BVM is designed in modular form where one BVM device is used for each battery or ?jar? in the string to be tested. One BVM for each battery connects to the next in a ?daisy-chain? fashion, thereby providing easy and economical expandability to meet the testing requirements for small-to-large battery bank systems.
The included dolphin clip can be easily removed and exchanged with different styles of standard banana plug clamps and / or extension cables to accommodate any battery connection requirement.
Setup is fast and easy using the BVM. Each BVM is identical and can be connected in any battery test position, thus providing maximum flexibility and interchangeability of the BVMs. Up to 120 BVMs can be daisy chained in a single battery bank under test. The BVM ?Auto Discovery? feature* enables the host device to automatically determine the number of batteries under test and provide sequential identification of each BVM in the test string.
