Origo PhaseID System
The PhaseID System now
makes it possible to quickly
and easily determine
energized phase attributes
anywhere in your system.
Use it on primary,
secondary, overhead,
underground, livefront,
deadfront, transformers,
switching cabinets,
substations, and standard
120-volt receptacles.
How it Works
The basic concept of the PhaseID
System is very simple. GPS
timing signals are used to
obtain snapshot phase
measurements at an unknown
field location and at a known
reference location at the same
instant of time.
When these two measurements
are compared, the phase
attribute at the unknown field
location can be determined.
Why it is Needed
Simply put, complete system
phase knowledge is
required to operate a
smooth, balanced, efficient,
well maintained utility.
For example, phase
knowledge allows
distribution load balance to
be obtained and maintained
as new customers are
added.
Benefits of Phase Identification
Geographical Information Systems (GIS)
These systems are only as good as the data they contain. When GIS phase attribute data is incorrect, the
usefulness of these important data bases are greatly diminished. A phase identification system allows you
to easily and accurately correct your phase maps.
Reduce Outage Management Errors
An accurate outage management data base allows a utility to instantly determine which feeder has tripped
based on customer outage calls. However, if the phase attribute data associated with individual customers
is wrong, time is wasted directing a troubleman to the wrong fuse or breaker. A phase identification system
allows you to correct these data base errors.
Load Imbalance
As new customers are added, or due to seasonal load changes, feeder loads may have to be re-balanced
by switching loads from one phase to another. If the phase load being switched is connected to one that is
not accurately known, phase balancing becomes a time consuming and frustrating process. Instead of
moving load from “C” to “A”, you might be really moving load from “B” to “C”, which makes the problem
worse instead of better. With a phase identification system, cables can be accurately tagged.
Wasted Crew Time
Hours are wasted daily with entire crews waiting while attempting to identify phasing. The current practice
of “driving a line” to determine phase is no longer necessary. A phase identification system can accurately
determine phase anywhere in a matter of minutes.
Neutral Current
This is an area utilities have not spent much attention to because, prior to the availability of phase
identification systems, there was no cost effective way to address it. Neutral current is caused by
unbalanced phase currents and results in wasted energy. Although not possible to totally eliminate neutral
currents, reducing them by using a phase identification tool to balance feeder currents throughout your
system can save hundreds of thousands of dollars per year in wasted energy costs.

lack of cellular coverage
• Use on any voltage
• Very portable (only 3 lbs)

Phase Measurement Comparisons
• The reference phase base station can be connected
to any convenient wall socket of any phase.
• Each GPS second, the wall socket phase is
measured and stored in a PC file.
• When touched to any energized line, the field probe
measures the unknown phase at the next GPS
second and encodes it into a 9-digit sequence.
• Base and field measurements can be compared at
any convenient time and manner by simply entering
the 9-digit sequence into the PC.
Available in Handheld or Lineman
Available in Manual or Datalogger
Manual Version
• Non-Real-Time phase
attribute determination.
• Write down the phase
sequences and enter them
into the base station later.
• Call your dispatcher, or any
other utility personnel, and
give them the 9-digit
sequence. They will enter it
into their PC and tell you the
phase attribute.
Datalogger Version
• Real-Time phase attribute
determination if Internet
access available.
• Automatically records the
phase sequence in a
measurement file.
• Provides GPS location.
• Accepts user notes.
• Real-Time Satellite
communication link available
soon.

Tagging Reference Phase
• Tagging reference phase is one of the most important
concepts of phase identification.
• Tagging reference phase simply refers to what phase
attribute you wish to call each 3-phase conductor.
• There is no universal “Phase A”. Phases A, B, and C
are simply the phase attributes the utility wishes to
tag or assign to each of the 3-phase conductors.
• Once assigned, all conductors of the same phase are
tagged according to this chosen tagging reference
phase.

Batch Convert
• All measurement sequences can be converted to
phase attribute with a single click.
• First, copy the base station daily reference file into
the field PC data directory.
• Next, click on the third icon to the right of the
measurement sequence window (red-to-green icon).
• This action converts all measurement sequences to
phase attributes and changes all red dots to green
dots.
