PowerCET takes the uncertainty out of solving power issues, i.e.; how to perform power studies, choosing the right power monitoring system, what accessories you will need and whether to rent or buy. Choose a complete setup from our inventory of meters from Dranetz-BMI, Fluke, Power Standards Lab, and others. Call to discuss your needs with us. We'll make sure you get the right system, and we'll train you on how to use the equipment, and how to analyze the data.

Power monitors for power quality, energy use, and data logging.

Start here to choose the right power monitor for your application

We'll help you choose. These are the application considerations:

Do you want to just log voltage and current?

Almost all power monitors will log voltage and current. I.e. provide a recording of voltage and current values over time, such as a few hours, a week, a month or longer. You can get graphs of V and I values, and usually tables of values that can be imported into Excel.

Some models of power monitors are intended for data logging only, and are the lowest cost. Other models are also capable of making other measurements, the more capability they have, the higher their cost! We'll help you choose the right instrument to do the job without paying for more than you need. We'll discuss with you the length of time you want to log for, and we will advise you on the level of detail (or granularity) of the log records you'll need to solve your problem. We'll talk about what sampling rates will be appropriate, and how the data is averaged (or reduced) depending on how much memory is available in the data logger. 

Typical applications include: monitoring circuit loading, equipment behavior such as current draw and cycling, panel capacity studies, connected load studies, voltage regulation. 

Do you want to monitor energy use, power consumption, or perform an energy study or audit?

Power consumption and energy use studies require monitoring of voltage and current, and then calculating the power in Watts, plus calculating energy consumption in kWh. Similar to loggers, you can get graphs of Watts over time, as well as other related power values such as power factor, reactive power in VAR, and apparent power in VA. Data can be exported to Excel. Often, power studies involve monitoring several loads, or panels, or multiple locations simultaneously. Call us to discuss your situation, we can supply a single monitor, or multiple monitors.

Typical applications include: energy audits, power consumption studies, reducing peak demand charges, power factor evaluation, verifying generated power in solar or wind projects, building or campus-wide energy studies. 

Do you want to investigate a power quality issue? 

Do you have a concern that an equipment or a process is not operating reliably and the cause may be power related? Do you have intermittent power interruptions, overheating of transformers, lights flickering, breakers tripping, the list goes on...

So you need to investigate and monitor the power to either find out if it is power-related, or to eliminate power as a cause and prove it is perfectly OK. The main areas that we, as power quality consultants ourselves, look into for assessing power quality are:

RMS voltage to find out if sags (low voltage conditions) or swells (high voltage conditions) are occurring.

Fast voltage spikes, usually referred to as transients or impulses. These are fleeting high voltage phenomena that can disrupt electronics and cause damage.

Harmonics, and waveform distortion. Ideal power has a perfect sine-wave shape, but that's not often the case. If the power waveform is not a pure sine-wave then it is said to be distorted. Low levels of distortion are common and not usually a problem. It can be tricky to understand whether the amount of waveform distortion is serious or benign. We have much expertise in understanding harmonic distortion, and we'll advise you on your situation.

Frequency stability. Usually the utility grid is stable at 60 Hz, but there are occasions when the grid is disrupted and frequency deviations occur. Our common experience with frequency-related problems usually involve UPS systems in data centers, and with back-up generators. We are often consulted to commission the start-up of UPS systems and generators to verify their performance.

Before choosing any instrument for the above studies, what about installation, programming, and getting reports? 

The physical installation needs to be considered. Is the study being done indoors or outdoors? How will the test leads be connected? Is there enough space? What type of current probe to use, flexible or rigid? Safety needs to be taken into consideration both during the installation, and to ensure it is not a hazard during the time it is recording since it will be left to do its work unattended. We have devised methods for locking monitors to prevent tampering, or mounting them out of harms way. For outdoor projects we can discuss weather protection options.

Are you new to using power monitors? Don't worry we'll help. We can even consult and perform the study for you if you would prefer? This could be a good option if you don't have the time and people resources to perform the study and analysis yourself. Or, we can train you. We offer on-line training and support, classroom-type seminars, or at your site (fee-based). 

We'll discuss with you the various software programs, and how to generate final reports. You may prefer to download the data to a PC and view and format the date yourself. Or, you may like the idea of getting graphs and reports by email, automatically. This is especially attractive if you need to monitor a remote site that could involve repetitive trips to install and set up, and return trips to retrieve the monitor and data. This can become expensive and time-consuming, but we have a great solution to minimize costs. Field-service organizations please take notice!

Do we have a favorite monitor? It depends on the situation. We have several types, and can advise you which monitor will work best for you. This is where PowerCet's wealth of experience can help you, so we invite you take advantage of it. We have used all brands over the past 25 years, done numerous studies, solved many problems, and trained many industrial, commercial, and government organizations. We like to think of ourselves as the "ghost-busters" of power!

If you are experienced and know what you want, great! We can supply you with one or multiple instruments, for indoor and outdoor applications.

If you are not sure what approach to take please talk to us before you buy or rent, call: 408 988 1346
