Topic: Expert Guidance on Standby and Emergency Power Systems

Date: May 26, 2011


You must get 12 of 15 questions correct to pass the exam. You may retake the exam if necessary. You will be notified whether you passed or failed automatically after taking the exam. Upon passing the exam, you will be given the authority to download a certificate indicating you passed the exam.


This webcast presents two experts on the design of standby and emergency power systems in a special 90-minute event that will be conducted in two parts.


Part one will provide a detailed examination of large UPS technologies based on testing that also helps engineers balance traditional requirements of reliability and availability with energy efficiency and other sustainability concerns. Part two will provide a detailed discussion of the differences between standby and emergency power systems, and how to meet real requirements without incurring unnecessary and costly design errors and equipment purchases.

  • Part 1: Large UPS Systems: Performance, Reliability, and Efficiency
    • Speaker: Dennis P. DeCoster, Executive Principal at Mission Critical West, Inc. 
  • Part 2: Optional Standby vs. Emergency Power Systems: The alarming and costly differences
    • Speaker: Tom Montgomery PE, Director of Las Vegas and Wyoming Operations, Henderson Engineers, Inc.

18.) Based on the presentation given by Tom Montgomery: *

Emergency power systems are those systems legally required and classed as emergency by municipal, state, federal, or other codes, or by any governmental agency having jurisdiction

True
False
19.) Based on the presentation given by Tom Montgomery: *

Legally required standby systems are intended to supply, distribute, and control power and illumination essential for safety to human life.

True
False
20.) Based on the presentation given by Tom Montgomery: *

An optional standby systems are intended to automatically supply power to selected loads (other than those classed as emergency systems) in the event of failure of the normal source.

True
False
21.) Based on the presentation given by Tom Montgomery: *

When the normal power source is not available, the emergency power system (EPS) shall be permitted to serve optional loads other than system loads, provided that the EPS has adequate capacity or automatic selective load pickup and load shedding are provided as needed to ensure adequate power to (1) the Level 1 loads, (2) the Level 2 loads, and (3) the optional loads, in that order of priority

True
False
22.) Based on the presentation given by Tom Montgomery: *
