Power Monitoring Services in Phoenix, Arizona

We record voltage, current and power on your panel or equipment for days or weeks, so you can see what is really tripping breakers, dimming lights or killing motors.

What is power monitoring?

Power monitoring means installing a recording meter on your panel, feeder or a single machine and logging voltage, current, power and power quality over time, usually 7 to 30 days. Instead of guessing why something keeps failing, you get a timeline of exactly what the electrical system was doing when it happened.

It is a close cousin of an electrical load study. A load study answers "does my building have the capacity?" Power monitoring answers "what is going wrong right now?" If you need the capacity question answered, see our Electrical Load Studies page.

What problems can power monitoring find?

Phoenix summers push every system hard, and monsoon season brings outages, surges and sags that can damage equipment. Monitoring catches what a one-time visit misses.

  • Tripping breakers: See whether the cause is a real overload, a short surge, or a breaker that is failing early.
  • Voltage sags and surges: Catch brief dips and spikes that reset equipment or shorten its life.
  • Overloaded panels and feeders: Measure actual peak demand against what the panel is rated to carry.
  • Unbalanced phases: Find three-phase loads that are uneven and running motors hot.
  • Harmonics and noise: Identify electronic loads that distort power and overheat transformers and neutrals.
  • Motor and equipment starts: Record inrush current from compressors, pumps and HVAC equipment.

How does power monitoring work?

  1. Walk-through. We look at the panel, the equipment having trouble and what has already been tried.
  2. Install the loggers. We clamp Fluke power quality loggers onto the panel or feeder. No shutdown is needed in most cases.
  3. Record, then report. The loggers run for the agreed period. We pull the data, read the events and write up what we found.

What do you get in a power monitoring report?

  • Peak and average current and demand by phase
  • Voltage min, max and any sag or surge events with time stamps
  • Phase balance and power factor
  • Harmonic readings where relevant
  • Plain-language findings and a recommended fix
  • Raw data on request

PCS assists with the data collection and electrical findings. Any engineering calculation or stamped study is performed by the engineer of record.

Who uses power monitoring?

Property managers with recurring outages, manufacturers with failing motors or drives, restaurants and retail with tripping breakers, homeowners with a pool, EV charger or ADU addition they are unsure the panel can support, and engineers who need real load data for arc flash, coordination or load studies.

Can PCS fix what monitoring finds?

Yes. Monitoring is only useful if the problem gets fixed. Depending on what the data shows, we can help with:

OUR PROCESS

HOW DOES A JOB WITH PHOENIX CONTRACTING SERVICES WORK?

Every job follows three steps: a site walkthrough, testing and documentation, then findings and next steps.

01

WALKTHROUGH AND SCOPE

We visit the site, look at the panels and service, and agree on what needs to be tested or repaired before any work starts.

02

TESTING AND DOCUMENTATION

Load loggers and a thermal camera record what the equipment is doing, and the results are documented for each panel or component we check.

03

FINDINGS AND NEXT STEPS

We go over what we found and your options in plain language. If corrective work is needed, we are licensed to do it.

How much does power monitoring cost in Phoenix?
Cost depends on how many circuits or panels we monitor and for how long. A single machine or one panel for a week costs much less than a multi-panel site over 30 days. Tell us what you are seeing and we will quote it after a short call or walk-through.
How long does power monitoring take?
Most jobs run 7 to 30 days of recording. Setup takes under an hour per panel in most cases, and we deliver the report within a few business days after we pull the loggers.
Can you monitor a single machine or circuit?
Yes. We can log one machine, one circuit or a whole service entrance, depending on where the problem shows up.
Will monitoring tell me for certain what caused the problem?
Often, yes, if the problem happens during the recording period. If the issue came from the utility side, such as an APS or SRP voltage event, the data shows that too, so you have evidence to take to the utility. Some intermittent problems need a longer recording window, and we will tell you that up front.
What do you need from me to quote it?
The type of building, what is failing or tripping, the panel's main breaker size if you know it, and how often it happens. Photos of the panel label help.
