Learning Objectives:

  1. Identify the fundamental backup generator and power system components.
  2. Examine the relationship between various generator specifications (kVA/kW/PF) and engine horsepower.
  3. Recognize the impact of load characteristics on a generator’s requirements.
  4. Comprehend the implications of under-sizing or oversizing the generator and fuel run-time.

Society is extremely dependent on electrical power. It is the underpinning of virtually everything we take for granted in everyday life at home, work, and, in many cases, public and commercial transportation. Virtually all of the critical infrastructure for communications, security, emergency services, and life safety depend on power.

Unfortunately, climate change and record weather extremes are likely to increase the likelihood of more frequent and extensive utility power interruptions as well as risks to life and property. This will place a greater demand for energy security and resilience, causing more facilities to install on-site, backup power systems. This represents a long-term investment in a critical asset and, therefore, it’s important this investment will meet present load requirements as well as any reasonably foreseeable future requirements.

Generally speaking, many generators are simply selected by kVA capacity. While this a good starting point, there are other factors that need closer examination, including the type of loads the generator is required to support, fuel autonomy, the rate of fuel consumption under different conditions, and more.

This webinar will discuss the Generator Capacity Ratings components and systems.
