Description
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 daisychained 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.

Application
Each BVM is identical and can be connected in any battery test
position. Up to 120 BVMs can be daisy-chained in a single battery
bank under test.
A single cable connects the first BVM in the string to a Power &
signal connector. The laptop or other data acquisition device is
connected via an Ethernet cable to the Power & signal connector.
The last dolphin clip (red) in the chain should be connected to the
positive battery pole of the last battery in the bank.
When used together with TORKEL the voltage will be logged
through the complete discharge test.
