15 - Protecting from poor AC (mains) and DC power quality - Updated Jan 2021
Provides 1.5 hours towards CPD
Included with Subscription.Details
This module helps engineers understand that mains power suffers from many electromagnetic disturbances....
– surges, spikes, transients, bursts of fast transients, electrostatic discharge, common-mode radio-frequency (RF) voltages and currents, etc...
– all of which are common to all conductors and are dealt with by our other course modules
This module covers ‘non-RF’ mains power quality issues. ie. Frequencies <150 kHz
The module is 82 slides over 41 pages
2) Overvoltages (swells)
3) Frequency variations
4) 3-phase unbalance
5) DC in AC supplies
6) Common-Mode Low-Frequency voltages
7 ) Undervoltages (sags, brownouts, dips, dropouts and interruptions)
8) Voltage fluctuations
9) Waveform distortion (harmonic and interharmonic)
10) Improving the quality of the mains supply itself
11) Tripping out
12) Some useful references

Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.Join EMC standards TODAY!
