Battery banks have become an inseparable part of uninterrupted or back-up power supply arrangements in various industries like Power, Telecom, IT etc. In substations the critical protection, control & communication systems run on battery power. Hence the reliability of these battery banks is crucial to ensure smooth operation of equipment which they are serving. The capacity of battery may get reduced significantly before the expected life span of battery due to various reasons. The only way to assess the continual health of battery banks is periodical maintenance inspection & testing. Conducting a discharge test on batteries is most effective way to check the battery capacity. SCOPE introduces BLUe Series Battery Loading Units; these are moveble instruments for controlled & monitored discharge of batteries. They are designed for integrated site discharge test, design & QC test and also for monitoring discharge process of battery bank with connected load. Each single autonomous unit having built-in display, keypad and wireless communication with computer makes it very easy to use. It comes in different configurations ranging from 12V to 380V discharge voltages and 50A to 300A discharge currents. Various options are available to control & monitor the discharge process. With the help of optional Cell Monitoring Unit – CellMon, voltage of each individual cell can be monitored & data sent to main BLUe unit and then from main unit to computer via wireless communication. Each BLUe unit is supplied with computer downloading & analysis software for real time monitoring of discharge process.
