About this course…
There are various philosophies and opinions for maintaining and testing battery systems. These approaches can range from the “Do nothing and replace when the battery fails” to the “Intense time- based battery maintenance regimen”. Obviously the “do nothing” approach appears a little flawed. Keep in mind that a battery is a perishable item with a shelf life.
Besides being perishable, another unique feature of a battery that is unlike other electrical assets is that a battery uses chemicals, metal alloys, plastics, welds, and bonds that must interact with each other to produce a constant DC source. For this reason, the type of battery (Flooded lead-acid, sealed lead-acid or nickel-cadmium) should be considered before embarking on a battery maintenance program. There are several recommended practices for battery testing. They will typically comprise of inspections, actions, and measurements conducted under normal float conditions and capacity tests performed with the battery system off line.
This training course will introduce students to stationary batteries and the maintenance and testing they require. The student will learn to identify various types of batteries, their construction and applications. The student will define safety and hazards related to batteries and testing. We will look at various failure modes related to batteries and how to identify each failure. Tests and inspection procedures will be explained along with the interpretation of test results.
Who should attend…
This course is designed for industrial professionals working on battery systems in substations, power plants, data centers and in other systems that require emergency and standby DC power.
This course is designed to have approximately 30% hands-on lab sessions. Students should have a command of basic electrical principles for both AC and DC circuits prior to attending this course.
Course Length 4 days (32 contact hours)
Each student will receive course text.
