DC systems are a vital component of any modern substation, providing power to protection and control
equipment in times of AC power loss. Failure to provide the backup power to protection gear to clear a fault
can be catastrophic.
The problem with batteries is that there is no way of assessing their health by visual inspection alone. Often a
battery recently installed that looks perfect on the outside can be totally corroded inside. The battery charger
also plays a big part in the reliability of the system. A badly regulated or badly filtered battery charger can
damage or even explode a perfectly good battery in a matter of months if not weeks! Metering on the DC
systems can also be misleading. They may be showing the right values but in reality, the battery may be
under or overcharged.
It is therefore essential that DC systems are reliable and ready for action all the time and this necessitates
maintenance both for batteries and chargers.
Servicing Options
Six Monthly Service
This ensures that the charger and the batteries are
operating correctly and can provide protection
power for the switchgear when needed. The six
monthly service includes:
1. Functional check of the charger to
ensure it is working correctly.
2. Assessment of components for stress
and fault.
3. Battery electrolyte assessment (if
applicable) and top up when required.
4. Battery terminal corrosion check and
general battery clean.
5. Float voltage review of each battery cell
and the battery bank.
Note : These tests can be done without
interruption to the normal operation of the charger.
Annual Service
This ensures that the charger is functioning
correctly and measures the present capacity of the
battery. The DC system needs to be shut down
during the annual service and includes all six-
monthly service items PLUS:
1. Load testing of the batteries to
determine battery health and identify
replacement needs.
2. SG testing on the battery electrolyte (if
applicable).
