Substation Battery Testing - DVD
Periodic battery testing helps determine when and what kind of maintenance a battery needs. Testing helps verify the physical condition of a battery, its state of charge, and its ability to operate when needed. This 33-minute DVD explains the basic steps for battery voltage and resistance testing, specific gravity testing, integrity and capacity testing, and impedance testing.
Voltage and Resistance Testing – 7 minutes
States the purpose of and describes the basic steps for checking cell voltages, and intercell connection resistances.
Specific Gravity Testing – 8 minutes
States the purpose of and describes the basic steps for checking specific gravity. Explains the effect of temperature on specific gravity.
Integrity and Capacity Testing – 12 minutes
Describes the principles and purposes of integrity testing and capacity testing. Identifies the basic components of a typical test set used for both integrity tests and capacity tests. Describes the basic steps for performing integrity tests and capacity tests.
Impedance Testing – 6 minutes
States the purpose of impedance testing and the components of a typical impedance test set. Identifies the components of a typical impedance test set.
