Introduction
Describe problem & define objectives
Choosing instrumentation, past & present
Summit’s range of hand-held analyzers
Data retrieval & analysis
Documentation & reports
Conclusions
Define Problem
“I need to add more loads – will my panels and circuits support the new
additions?”
“We need to reduce energy consumption – I need to perform an energy
audit to evaluate energy savings opportunities.”
“This transformer is very hot – is it overloaded or are high harmonics
the cause?”
“My (machine) is operating erratically – is power quality the cause?”
“When the HVAC (or motor or other equipment) turns on the breaker
trips.”
“I’m commissioning a UPS and need to verify it’s performance.”
“My one-line diagram is out of date or missing, I need to recreate it.”
“I need to measure system impedances for an Arc Flash study.”

To Display or Not Display
• Unattended long-term monitoring and logging does not
require a display
For long monitoring periods no one is looking at the monitor
Analysis done off line
Use PC as display for analysis and reports
Good security – small size, less conspicuous
• Attended short-term monitoring sometimes requires
oscilloscope display
Witness conditions as they occur
Forcing events, changing of waveforms
Usually during commissioning and set-up of equipment
Poor security – video game
Connecting Safely
•
•
•
•

Terminal blocks danger!
Banana plugs – stacking is a hazard
CAT IV rating - highest level of transient overvoltage
Neutral conductor?
Verifying connections by experience
Indicator lights – go, no go
Display – phasors, rotation, polarity
Intelligence – checks all conditions
CT’s self-identify

Monitor power without exposure to high
voltages
No need to wear special gloves, eyeprotection, or flame-retardant clothing.
No need to power down.
No need to put up protective barriers or
warnings.
Quick setup and teardown of monitoring
sessions on live power.
No need to remove panels.
No need to deal with hooking up current
probes in tight or inaccessible spaces.
Periodic maintenance measurements.
No switched phases, reversed probes,
or dead channels.
Permanent connections means the data
is right when you return 1 month later.

•
•
•
V & I data logging most common study
Energy analyzer addresses 60% of studies
Sags/swells are most common PQ problem
Harmonics and high speed transients less significant
Display need depends on attended/unattended operation
New breed of hand-held analyzers pack high performance
Unique options for high-voltage, noise, motor diagnostics
Report writer completes the job
