Power Quality Analyzer Rental
In order to function at their optimal levels, electrical motors require a steady, good quality source of power, preferably without current or voltage spikes, and with good harmonics. Many of our customers leave these units hooked up to the power circuit for weeks at a time and come back to analyze the current data to look for any abnormalities.
Which Power Quality Unit Should I Choose
The concern of the impact of power quality on the cost of power, combined with the fast proliferation of power-hungry precision servers and machines has caused the power quality monitoring sector to explode in recent years. Transcat sells a variety of power quality tools from manufacturers like Fluke, Dranetz, Hioki and others, and we also rent the top Fluke power quality instruments.
How do I choose the right tool?
One of the common questions we face is how to choose the right tool for the job. A selection guide of power quality tools can help compare the specs, but it's hard to match the specs to the particular need. This article will focus on the top four questions to ask before choosing a power quality instrument.
Question no. 1: Am I testing three-phase power or single-phase only?
While most three-phase units will allow you to measure single-phase power, if single-phase is all you are testing, the Fluke 43B should be sufficient for your needs.
Question no 2: How fast do the triggers need to be?
This question is really about monitoring events. If all you need is information about general power consumption and reliability, the Fluke 1735 or the Fluke 1736 are all you need. These are by far the most popular pieces of PQ equipment, and they are typically used in 30-day power audits. Their minimum logging interval is 1 second, so if you need more detailed information, you will need to go a level further up (see Question no. 3).
Note that the Fluke 1736 can be set up to be monitored remotely via its IP address. The Fluke 1735 does not have this functionality.
Question no. 3: Do I need to monitor events and harmonics? If so, in what detail?
This is the final decision question. The Fluke 435-II and Fluke 437-II offer event triggers and logging to a fraction of a second, which makes them ideal for monitoring and testing events like power switchovers and unexpected short dips and spikes. Both also offer the ability to monitor basic transient capabilities.
The Fluke 438-II is a new unit that can also analyze electric motor performance by comparing the power consumption profile of the motor to what it should be.
Finally, the Fluke 1750 offers detailed waveform capture and advanced transient capabilities for catching even the hardest-to-capture events.
