Battery monitoring system uses fiber optic technology

The Powerware Cell Watch battery monitoring system is designed specifically for three phase uninterruptible power systems (UPS). The system uses the latest fiber-optic technology providing rapid, noise-free transmission of information. The modular system continuously monitors the entire battery system, including string and cell level voltage, internal resistance, current and temperature, throughout the charge, discharge and float periods. It adds an additional level of prediction and control to the enterprise maximizing systems availability. The system provides immediate warnings of a deterioration and imminent failure of batteries and reduces the possibility of damage to the entire battery string. Invensys Power Systems
