Power quality management and arc flash safety
- COURSE OUTLINE
- SPEAKER BIO(S)
As a result of this course, you will be able to:
- Discuss common voltage sag disturbances, origins, impacts and solutions.
- Describe causes and solutions for momentary interruptions.
- Distinguish the differences between power quality and reliability.
- Explain important elements of any arc flash safety program.
Who should attend?
Electricians, engineers, operators, contractors, facility managers, account managers and representatives, electrical service planners, new construction workers and anyone involved in operating or managing electrical equipment and systems where electrical power quality is a concern.
Gain a solid understanding of electrical power quality and its impact on your facility. We’ll dive deep into solutions to ride through momentary interruptions, voltage sags, waveform distortions and more. In addition—since modern energy efficient equipment is more complex and sensitive to power quality disturbances—we’ll discuss equipment purchasing decisions and what should be taken into account. We’ll also explore arc flash safety: What is it? What components should be considered in a facility’s arc flash safety program? Finally, prior to concluding this course, we’ll allow ample time for you to ask questions specific to your facility.

- Power quality versus reliability
- Reliability: is the power on consistently?
- Regulatory reliability definitions (SAIDI, SAIFI versus standards)
- Power quality: does the equipment work correctly?
- Power quality disturbances can be measured in microseconds
Five power quality disturbance categories and impacts
- Interruptions, short term voltage fluctuations, long term voltage fluctuations, transients (spikes), waveform distortion (including harmonic distortion)
Identifying power quality issues and problems
- Elements of a strong power quality program
- Identifying the disturbance is important
- Internal power quality and equipment operation logs
- Eliminate the disturbance or immunize the equipment?
- Equipment purchasing strategies versus existing equipment
- External monitoring and your utility ally
- Internal monitoring: what, where and how?
Power quality ride through solution options
- Type of disturbance and duration time are important
- Do you want to immunize the equipment from everything?
- How much ride through protection is needed?
- Industry standards (ITC, SEMI and IEC ride through curves)
- IEEE 519: how much harmonic distortion is acceptable?
Power quality ride through technologies: purchase considerations
- Battery backups: what they do and don’t do?
- Switching time and voltage is critical
- Uninterruptible power supplies: will they do it all?
- Is a UPS susceptible to power quality disturbances?
Motor-generator sets for shorter disturbances
- Standby generator with automatic transfer switch
- What type of transfer switch?
- Constant voltage transformers: where do they fit?
- Static VAR compensators: infrequent short term sags
- Active/Dynamic VAR compensators: what do they do?
Surge suppressors: what disturbances can be mitigated?
- How much of a surge is too much?
- Understanding surge suppression ratings and what they mean
- Surge suppressors: advantages, disadvantages and alternatives
Filter, chokes and reactors: what disturbances can be mitigated?
- How much is too much? (IEEE 519 Limits)
- Understanding filter, choke and reactor ratings and what they mean
- Alternatives to filters, chokes and reactors: higher pulse number drives, isolation transformers, computer grade transformers and K-factor transformers
What is arc flash safety and why is it a concern?
- Arc flash history
- Codes and safety rules that apply? (OSHA, NFPA, NEC, etc.)
- Five steps to implementing and maintaining arc flash safety programs
Arc flash program components and considerations
- Arc flash calculations versus arc flash tables
- What information do I need from my power supplier?
- Arc flash boundaries and labeling
- Why don’t manufacturers put arc flash labels on equipment?
- Are there general guidelines we can apply to a piece of equipment?
- Implementation, enforcement and documentation

“How do I know I have “dirty power” if I can’t see it, smell it, taste it or touch it?”
“We used to think of power quality in terms of “are the lights on or off.” In modern buildings today there are electrical disturbances we never see that disrupt operations fast enough to be measured in micro-seconds.”
