3. AIRPORT EMERGENCY DIESEL PREVENTIVE MAINTENANCE MANAGEMENT USING BATTERY INTERNAL RESISTANCE MONITORING ANALYSIS

Abstrak

Emergency diesel generator is a very important system in every industry including
the airport industry because this system supports the electricity of important equipment when
a blackout occurs. in the emergency diesel generator system, there is a battery as a starter for
the diesel engine. if the battery capacity decreases, the diesel generator will not be able to
start the engine, therefore in the emergency diesel generator system, regular battery
maintenance is needed to maintain system reliability. in this journal, preventive maintenance
on the battery will be explained, especially on the emergency diesel generator system battery.
one indicator of decreased capacity in the battery is an increase in its internal resistance value.
in preventive battery maintenance, analyzing the increase in internal resistance can be a
reference for replacing a new battery.
