IEEE Standard 1159-1995:
The Revised PQ
MonitoringStandard
Randy Collins
Chair, 1159 Working Group
IEEE Power Engineering Society Winter Meeting
New York
January 28, 2002
Benchmark Document
Monitoring of Electric Power Quality of
single and polyphase systems.
Descriptions of phenomena.
Definitions of nominal and deviations
from nominal.
Recommendations for measurement
techniques, application techniques, and
interpretation of monitoring results.
Purpose
The purpose of 1159-1995 is to direct
user in the proper monitoring and data
interpretation of electromagnetic
phenomena that cause power quality
problems.
Purpose cont’d
Defines power quality phenomena to
facilitate communication within the
power quality community.
Forms the consensus opinion for safe
and acceptable methods for monitoring
and interpreting results.
Tutorial on power system disturbances
and common causes.
The next 1159…
At a minimum, 1159 needs to be
updated and include links to the
forthcoming 1159.1 and .3 works.
What do we want the final product to
look like?
Some ideas…
Ch. 1. Overview
Expand and include information about
“why would you want to measure for
power quality?”
Ch. 2. References
Revise and update
Ch. 3 Definitions
Terms used in this recommended practice
Avoided terms
Abbreviations and acronyms
Expand with the former P1433 information
Pull definitions from .1 and .3 documents
Can we use and define terms not used in the
document?
Would this be difficult to ballot?
Ch. 4 Power Quality
Phenomena
Electromagnetic compatibility
General classification of phenomena
Detailed descriptions of phenomena
Table 2 is probably the most widely used
part of the Standard.
Update the graphs.
Expand the explanations.
Ch. 5 Monitoring Objectives
Need for monitoring PQ
Equipment tolerances and effects of
disturbances on equipment
Equipment types
Effect on equipment by phenomena
type
Ch. 6 Measurement
instruments
AC voltage and current measurements
Voltage and current considerations
Monitoring instruments
Instrument power
Revise and update.
Incorporate some 1159. 1 information.
Ch. 7 Application techniques
Safety
Monitoring location
Equipment connection
Monitoring thresholds
Monitoring period
Ch. 8 Interpreting monitoring
results
Interpreting data summaries
Critical data extraction
Interpreting critical events
Verifying data interpretation
Expand this to include data reduction and
presentation info.
How do you present multi-dimensional info on a 2dimensional CBEMA/ITIC/SEMI curve?
Additional topics
Sort of a “case study” section, except
organize it by equipment categories.
What to monitor and look for, what you
don’t need to monitor for when
investigating problems with common
equipment:
ASDs, PLCs, Switching power supplies,
relays/contactors, lighting, etc.
Annexes
Annex A: Calibration and self testing
(informative)
Annex B: Bibliography (informative)
Keep this or not?
Keep this and update/expand.
New Annexes:
Technical summaries of the .1 and .3
documents.
Today’s objectives
Establish scope, purpose and other
items required for the PAR.
Determine a working outline and
chapters
Assign chapter chairs
Proposed Organization
Ch. 1 and 2 Intro

Ch. 8 Interpretation
and Statistical Analysis
Ch. 9 Examples of
using the standard in
the field
