What the site needed.
Station DC batteries support the plant's control, protection and emergency loads. A hidden defect in a single battery may only show itself when the batteries are called on.
What EDPN delivered.
EDPN supplied and serviced two GENEREX BACS battery monitoring systems for the 110 VDC station batteries — one for the Hoppecke OPzV batteries and one for the FIAMM OPzV gel batteries. Monitoring data are integrated into the plant DCS.

What followed.
As published by GENEREX, BACS cyclically checks the voltage, temperature and internal resistance of each individual battery, balances charging voltage, detects hidden battery defects, issues configurable alarms and helps maximise battery service life.
